2. GENERAL INFORMATION 2.1 Instruction This manual provides installation, operation and maintenance instructions for the JK-REC Type electronically controlled recloser. Before installing and operating this recloser, carefully read and understand the contents of this manual. 2.2 Read this Manual First Read and understand the contents of this manual and follow all locally approved procedures and safety practices before installing and operating this recloser. 2.3 Additional Information This manual cannot cover all details or variations in the recloser, procedures or process described, nor provides directions for meeting every possible contingency during installation, operation or maintenance. When additional information is desired to satisfy a problem not covered sufficiently for the user’s purpose, please contact your Jin Kwang sales representative. 2.4 Applied Standards The recloser is designed, manufactured and tested in accordance with ANSI C37.60, ANSI C37.71, ANSI C37.73, ANSI C37.85, IEC 60255-5, IEEE C62.41(1991), ANSI/IEEE C37.90.1(1989), IEEE C37.90.2(1995). 2.5 Quality Standards The recloser shall be manufactured according to ISO9001(1994) quality control system. 2.6 Acceptance and Initial Inspection The recloser is completely assembled, tested, and inspected at the factory. It is good condition when accepted by the carrier for shipment. Upon receipt, inspect the shipping container for signs for damage. Unpack the recloser and inspect it thoroughly for damage incurred during shipment. If damage is discovered, file a claim with carrier immediately. 2.7 Handling and Storage Be careful during handling and storage of the recloser to minimize the possibility of damage. In particular, protect the porcelain bushing in handling. Only use the lifting lug when lifting the recloser. If the recloser is to be stored for any length of time prior to installation, provide a clean, dry storage area. 2.8 Description New demands for managing distribution systems call for control devices inherently reliable and


10

ISO 9001 certified


intelligent. Customers require a built-in capability for data gathering and communication, along with an extremely low maintenance product. The Jinkwang electronically controlled, three phase automatic recloser (hereinafter referred to as “the recloser”) provides reliable and economical over-current protection for distribution circuit, ranging from 15 through 38kV. The recloser senses line current and automatically interrupts the phase of the distribution circuit to which it is connected when line current exceeds the minimum trip level. Next, it automatically recloses to restore ser-vice and monitors the line to determine if the fault has been cleared. If the fault is permanent, the recloser sequences to lockout after one, two, three, or four preset trip operations Once the recloser sequences to lockout, the recloser must be manually reset to restore service. Should the fault clear before lockout, the recloser will reset automatically for another sequence of operations. The recloser can also be set for non-reclosing operation (lock out after the first trip operation) The recloser can be remotely set for non-reclosing operation via the remote non-reclosing feature. The trip operations of the recloser can be all fast, all delayed, or any combination of fast operations and delayed operations up to a maximum total of four. Fast operations clear temporary faults before branch line fuses are weakened. Delayed operations allow time for fuses or other downline protective devices to clear to limit permanent faults to the smallest section of line. The Jinkwang type JK-REC recloser has a characteristic as followings. 1) The recloser meets actively in distribution line protection coordination that change variously by control technology that u se microprocessor, and are being operated locally or remotely. 2) Communication protocols to DAS make the automated protection coordination possible. 3) The control has a total of 48 built-in T-C curves, and a T-C curve, which has a time multiplier and a minimum response time applied to the fundamental curve and a high current lockout characteristic, allows programming via keypad or RS232 communication por t on the front of control panel. 4) Fault recording for analysis can be backed up using LCD display or handheld controller applying gradually fault recording that need in the maintenance on the distribution lines. 5) All operating parameters and settings are easily programmable via handheld controller or PC using RS-232 port on the front panel. 6) The control is equipped with the function of sequence coordination to prevent unnecessary operation of the upstream reclosers when two or more reclosers are being operated in series.

4.1 Tank The tank of the recloser is fabricated from cold rolled steel and plate. The material used is 304L stainless steel (SF6 Gas insulated type only)and the design thickness is a minimum 3㎜. 4.2 Switching module In contrast to the majority of conventional circuit breakers, this patented design incorporates three independent magnetic actuators: one per pole. This minimizes the number of moving parts, all of which are symmetrical about the central synchronization of the poles operation. The vacuum interrupter and the magnetic actuator are located at opposite ends of a hollow support insulator. The actuator armature is rigidly coupled to the vacuum interrupter moving contact by a linear drive insulator within the support insulator. This provides direct linear movement in both directions and avoids the use of rotating shafts, bearings and bell cranks. The result is a maintenance free switch module with a long trouble free mechanical life. The actuators are situated inside the frame. A synchronizing shaft connects the three poles and performs three functions:

▪

- synchronization of the poles operation

▪

- control of the auxiliary switches

▪

- link-motion drive of mechanical interlocks.

4.2.1 Magnetic actuator The actuator is held in its two end positions without the use of mechanical latches. in the OPEN position the armature is held by the opening spring. in the CLOSED position the armature is held by magnetic flux produced by a ring permanent magnet. This actuator has only one coil. To close and trip the actuator it is necessary to inject current into the coil in different directions. 4.2.2 Vacuum interrupters As soon as the vacuum interrupter contacts open, the interrupting current initiates a so-called “vacuum arc” that burns essentially in plasma originating from evaporated contact material. The current continues to flow through this plasma until a current zero. At this moment the arc is extinguished and transient recovery voltage appears across the open gap. If the contact surface is locally overheated it produces a lot of vapor, resulting in the deterioration of the vacuum followed by electrical breakdown. To avoid this, effective control of the vacuum arc is necessary. The most effective way to achieve this goal is to apply an axial magnetic field produced by the interrupting current itself. This method is implemented in vacuum interrupters developed. Several major benefits result from this design:

▪

High interrupting capacity

▪

Very compact dimensions

▪

Low chopping current (45 amps) This limits inductive switching overvoltage to safe values.

▪

Axial magnetic field minimizes contact erosion and ensures a very long and reliable life.

4.2.3 Operation of switching modules Closing In the OPEN position the vacuum interrupter contacts are held open by the force of the opening spring in the actuator acting through the drive insulator. To close the vacuum interrupter contacts a current pulse, derived from the closing capacitor in the control module, is injected into the actuator coil. The current in the coil produces a magnetic flux in the gap between the upper yoke and the

▪

actuator armature.

▪

Rising coil current increases the magnetic flux and the electromagnetic attraction between yoke and armature increases to overcome the restraining force of the opening spring. (Line1)


15

ISO 9001 certified


▪

The armature, drive insulator and moving contact start to move.

▪

As the armature moves towards the upper yoke the magnetic air gap decreases and consequently the magnetic attraction force increases. This increasing force accelerates the armature, drive insulator and moving contact to a closing speed of 1 m/s. This optimum speed ensures a complete absence of contact bounce and reduces the probability of pre-strikes of the vacuum gap before the contacts close. (Line 2)

▪

The accelerating armature also generates a back emf in the coil and reduces the coil current (Line 12) At contact close (Line 2) the moving contact stops but the armature travel continues for 2mm under rapid deceleration caused by compressing the contact pressure spring.

▪

At the limit of its travel the armature latches magnetically to the upper yoke. (Line 2a) The moving armature induced back emf collapses and the coil current again increases (Line 2a-3) saturating the ring magnet. This saturation increases the power of the ring permanent magnet to a level that generates flux to hold the armature in the CLOSED position after the coil current has been cut off by an auxiliary switch. ( Line 3) Testing has proved that this flux is sufficient to hold the actuator CLOSED even under vibration and impact conditions.

▪

The travel of the armature also compresses the opening spring in preparation for the next opening operation.

▪

The synchronizing shaft is also driven through 44°of rotation during the closing operation and provides position indication, auxiliary switch operation and mechanical interlocking actions.

Opening

▪

To open the interrupter a current of opposite polarity, derived from the opening capacitor in the control module, is passed through the coil for 1520 milliseconds. (Line 4-5)

▪

This current partially demagnetizes the ring magnet and reduces the magnetic holding force on the armature. Opposing forces from the charged opening spring and the contact pressure spring cause the armature to release and accelerate rapidly. After 2 mm of free travel it engages with the drive insulator and thus the moving contact.


16

ISO 9001 certified

▪


The peak force produced by the armature at this point exceeds 2000 N which ensures easy breaking of any micro-welds at the contact surfaces which can appear due to short circuit current action.

▪

The moving contact accelerates rapidly ensuring a high interrupting capacity. (Line 5)

▪

At full travel (Line 6) the armature, drive insulator, moving contact assembly is again held open by the opening spring force.

▪

The synchronizing shaft is also driven through 44° of rotation during the opening operation and provides position indication, auxiliary switch operation and mechanical interlocking actions.

Manual closing Closing can only be carried out through the control module. Manual opening The module may be manually opened. By rotating the synchronizing shaft a force exceeding the magnetic attraction forces of the ring magnet is applied to the armature, which then starts to move. As the air-gap increases the opening spring and contact pressure spring over come any magnetic holding force and the interrupter opens. Auxiliary switches All switching modules are equipped with thirteen auxiliary switches, six normally open (NO) and seven normally closed (NC). Auxiliary switches are operated by cam that is fitted on the syn chronizing shaft. One NC auxiliary switch is used for interconnection with the control module. All others are available for external use. Auxiliary switches ratings are shown in the table below. Parameters Type

6. RECLOER OPERATION Warning Do not reply on the open position of the open/lock handle(yellow color) or the contact position indicator; it does not ensure that the line has been de-energized. Always establish a visible disconnect. Failure to follow proper safety practices can result in contact with high voltage, which will cause severe personal injury. Caution Pushing the yellow manual operating and Lock handle to the closed position will not close the recloser. All close operations are initiated by the FTU-R200 microprocessor-based recloser control. 6.1 Closing Operation Closing operation should be performed with a close button on the control panel necessarily. But, before operating the recloser on the control panel, make sure a position of manual open& lock handle. Check whether the manual open&lock handle indicate lock position or not. Note: When the recloser is closed, the manual operating and Lock handle should be positioned in free condition(upward). 6.2 Opening Operation The manual operating and Lock handle(yellow color) in the recloser is used to open and lock out the recloser. If the recloser is opened with a manual operating & lock handle, it automatically operates to lockout. So, it disable in the electrical and supervisory closing. The manual operating and Lock handle is designed to be operated with a hot stick. Pulling down the manual operating and Lock handle open the main contacts of the recloser. Contact position is indicated by the open flag of the contact open indicator. The handle will remain down in the open position and not return upward in the close position. Therefore, when the recloser is closed, the manual operating and Lock handle should be positioned in free condition. Note: When the recloser electrically operates to lockout, the open/ lock operating handle will not drop by the open position. The handle remains in the open position only after manual operations are performed.

7. MAINTENANCE Warning Always use a hotstick when working with the recloser. Failure to do so could result in contact with high voltage, which will cause severe personal injury. Caution The equipment requires routine inspection and maintenance to ensure proper operation. If it is not maintained it may fail to operate properly. Improper operation may cause equipment damage and possible personal injury. 7.1 GeneralJin Kwang’s reclosers require inspection and maintenance to ensure proper operation. If the recloser is not adequately maintained, it may fail to operate properly. Even though the recloser has been designed as a low maintenance unit, maintenance interval depends on the local climatic condition. Jin Kwang recommends that the recloser be inspected and maintained for long life. 7.2 Frequency of maintenanceTo assure proper and trouble-free operation, reclosers must be maintained when they have operated the equivalent of a rated duty cycle. Note: ANSI C 37.61, “Guide fot the application, Operation and Maintenance of Automatic Circuit reclosers”, gives a procedure for converting the rated standard duty cycle into an equivalent duty cycle based on the actual operating duty of the recloser 7.3 Check the operation of low pressure indicatorThe recloser is filled with 0.5kgf/cm 2 of SF6 gas in normal service, however, if gas pressure drops to 0.1 ~ 0.2kgf/cm2 or less by means of any cause, a low pressure locking device works to prevent the operation of the switch manually and electrically (from local control panel and from remote location). At the same time, a low gas pressure indicator located at the side of switch will be shown and a low pressure indicator lamp on the control panel will illuminate to indicate that switch operation has been blocked. 7.4 Check the recloser visuallyInspect each of the bushing for breaks, cracks, burn or heavy pollution and other part of the recloser. 1) If polluted, clean the bushing. 2) If damaged, replace whole of the recloser with new one.

8. OVERVIEW 8.1 PROTECTION OF DISTRIBUTION LINE Distribution lines have their own equipment outdoors, the types of loads are various, and the configurations of the networks are flexible and complicated. There are many kinds of fault causes such as direct contact of trees or birds, natural phenomenon of lightning or heavy snow, and fault spread-out due to customer’s facilities. Among these faults, most of faults are temporary and the dominant fault type is ground-fault. For rapid fault detection and fault section isolation, blackout area minimization, many protection devices such as Recloser, Sectionalizer, and Line Fuse are adopted. Among these devices, Automatic Circuit Recloser is the most important protection device, whose main functions are fault current trip and autoreclosing. One distribution line has over 2 Reclosers of serial connections or Recloser – Sectionalizer - Line Fuse of serial connections. This configuration is the concept of Primary Protection and Back-up Protection. In other words, protection coordination is required in the way that a protection device nearer to fault point operates first to eliminate the fault and other devices farther from fault point are configured to operate later with time delays. 8.2 FUNCTION OF AUTOMATIC CIRCUIT RECLOSER When a fault occurs on the load side of Recloser installed location, Recloser detects fault current, trips fault current at high speed, and does reclosing actions after the set time to re-activate the faulted section. In case of temporary fault, the fault can be removed by itself according to high-speed trip and dead time before reclosing actions. But, in case of permanent fault, because fault current is still detected after trip and reclosing actions of pre-set counts, Recloser is locked out finally as opened. Recloser has the time delay element in protection function of its controller and can be freely configured for protection coordination with other protection devices.

9.5.2.3 IEC60870-5-104 IEC 60870-5-104 (also known as IEC 870-5-104) is an international standard, released in 2000 by the IEC (International Electrotechnical Commission). As can be seen from the standard's full designation 'Network access for IEC 60870-5-101 using standard transport profiles', its application layer is based on IEC 60870-5-101. IEC 60870-5-104 enables communication between control station and substation via a standard TCP/IP network. The TCP protocol is used for connection-oriented secure data transmission. 9.6 RECORDING 9.6.1 EVENT RECORDER This function is used to verify shortly the operated history or log of FTU in normal operation and fault situation. Event recording is triggered by power reset, set value change, operation of protection functions, system err or or self-diagnosis, etc., and eve nts can be stored including event occurred time, measured values of current/voltage and operation description. And, this recording fuction follows the FIFO (First In First Out) rule. Stored events can be uploaded to and listed on FTU PC S/W (FTUMan) through RS232C port on front panel.

9.6.2 WAVEFORM EVENT RECORDER Fault & PQM waveforms recording function are used to store the measured instantaneous current/voltage values of pre-fault and post-fault at 128 samples per cycle. Record length, trigger source and trigger position of pre/post-fault in recorded data are adjustable. The record types are 128 samples * 20 cycles, 64 samples * 40 cycles, 32 samples * 80 cycles, 16 samples * 160 cycles.


45

ISO 9001 certified


According to the purpose, operators can set the fault recording trigger source and trigger position of pre-fault/post-fault. Trigger position means the percentage position in recorded fault data, and the prefault data are recorded before this point and rest of the data are recorded as the post-fault after this point. The recorded fault waveforms are also uploaded to FTU PC S/W, and current/voltage waveforms at fault and protection elements operation can be analyzed with fault evaluation. This waveform recording fuction follows the COMTRADE file format rule.

13. PROTECTION FUNCTIONS 13.1 FAULT DETECTION FTU detects the Phase & Earth Fault and trip the breaker. The fastest operation time is within 45msec including auto-recloser operating time. There are 58 trip curves, which can be selected for fast and delayed operation respectively. The Curve can be edited by using several parameters, i.e. time multiplier, time adder and minimum response time. And high current trip element can be used for instantaneous trip. It is definite time characteristics. During cold-load condition, pickup multiplied by cold-load multiplier. During the cold-load condition, time-delayed curve is applied instead of fast curve. This function can be enabled or disabled by coldload multiplier. Earth fault detection function can be enabled or disabled by ‘Ground Protection Enable’.

13.1.4 TC CURVE FTU-R200 has 54 types of built-in TC curves including ANSI, IEC Standard curves. And customer can define additional 4 curves as his own curves by using PC Software. Basically, built-in curves have inverse time characteristrics, but can be easily adjusted by three parameters such as multiplier, time adder and minimum response time. In engineering step, the selection and adjustments of TC curves shall be done for the protection coordination with other protection devices in the feeder. The follwing parameters are related to change and editing of TC curve’s characteristics. ü

Time Multiplier

Time Adder

ü

Minimum Response Time

Time Multiplier is multiplied to the operating time of basic curve (TDM=1.0), then Time Adder is added to the resulting operating time of the curve adjusted by multiplier. Minimum Response Time defines the fastest operating time of the curve. The following tables describe the built-in TC Curve Type and the corresponding numbers in the setting. TC Curve graphs are shown in the appendix.

13.1.5 EXAMPLE OF TC CURVE EDITING 3-parameters are applied in the follwing order. The values in the parenthesis are examples. ü

Time Multiplier : 1.5

ü

Time Adder : 0.03

ü

Minimum Response Time : 0.1

In the next figure, for example, the curve A is the basic curve. Assume the operating time of the basic curve (A) at 16 times pickup current is 0.04 sec. When applying Time Multiplier, curve ‘A’ changes its shape, that is, the curve becomes less steep in time axis and operation time becomes longer by a multiplier at the same current value like ‘B’ in the figure. The operating time at 16 times pickup becomes 0.06 sec. Then Time Adder shall be applied. The operating time of the resulting curve ‘C’ is 0.09sec. Finally Minimum Response Time cuts the curve part, which is shorter than this time. Then the actual operating time of the example at 16 times becomes 0.1sec.

[ TC Curve Editing Example 1 ] There are two additional definite time over-current elements in the controller. The next figure shows 3stage over-current protection characteristics. The third stage is prepared for instantaneous protection. Therefore the harmonic restraint is not applied to third stage elements, but the second stage definite time over-current element.

13.1.6 AUTO RECLOSING SEQUENCE The FTU-R200 supports 3-shot reclosing with sequence coordination. For Permanent fault, under the condition of reclosing enabled, no other restraints such as cold-load, inrush and no High Current Trip, recloser will be locked out to open the Reclosing Count repeating trip and reclose according to the preset settings.

For example in the below figure, the reclosing sequence is organized in 2F2D, which means the Recloser protection function operates as Instantaneous(Fast) element during first 2 reclosing shots and operates as Time-Delayed element during last 2 reclosing shots. This composition also can be configured.

[ Permanent Fault: 3 shot Reclosing & 2F2D ] For temporary fault, if the fault is removed before the preset Reclosing Count and no fault is detected during the preset Reset Time, then the reclosing sequence is initialized to normal operation standby mode. When a fault is detected again during the Reset Time, the Recloser will be locked out after the remaining reclosing counts excluding the previously operated reclosing counts.

13.1.7 SEQUENCE COODINATION In case that there are over 2 Reclosers which operate in serial connections, Sequence Coordination function prevents unnecessary trip of source-side Recloser by instantaneous element due to load-side fault. When this function is set to on and the fault is restored to normal state by load-side Recloser during source-side Recloser’s time-delayed operation, source-side Recloser only increments the reclosing counts without tripping. However, source-side Recloser performs tripping at the last reclosing count. If the Reclosing function is disabled, Sequence Coordination function is no longer carried out.

13.2 COLD LOAD PICKUP Cold Load Pickup is the phenomenon that takes place when a distribution circuit is re-energized following an extended outage of that circuit. Cold load pickup is a composite of two conditions: inrush and loss of load diversity. The magnitude of cold load pickup current is a combination of non-diverse cyclic load current, continuously operating load current, transformer magnetizing current, capacitor inrush current, etc. The combination can result in current levels that are significantly higher than normal peak load levels. Cold load pickup current can be high enough to cause instantaneous overcurrent and/or time overcurrent relays to operate. Cold load pickup is primarily an overcurrent condition. If degraded voltage is also a concern, then the application of voltage sensitive relays should also be considered.


69

ISO 9001 certified


[ Cold Load Pickup Current Shape ] In Cold Load Pickup mode, without changing operational characteristics, pickup level is changed by the times of Cold Load Multiplier (0~10) and the characteristics of time-delayed element operate even if the setting is in the Instantaneous element. If the transient current goes down and retrains below the pickup level within Cold Load Duration, then the normal sequence mode is restored after Cold Load Restore Time. The Cold Load Restore Time is fixed value of 30msec. These setting exist for both phase fault and earth fault separately, and the value ‘0’ of Cold Load Multiplier means Cold Load Pickup Function disabled. Normaly Reclosing Sequence mode is applied.

13.3 SENSITIVE EARTH FAULT(SEF) DETECTION On the non-grounded network, it is hard to detect fault current because ground current of nongrounded network is much low. Therefore, FTU-R200 is designed to measure zero-sequence values from either external core Balanced Current Transformer (or ZCT) or Residual Connection of 3 Phase Current Transformers to detect earth fault in the non-grounded network. This function is generally called SEF detection. In case of earth fault in the non-grounded network, since very small fault current due to line capacitance component flows into the fault point from both sides, SEF detection also considers the fault direction even in the radial network. Maximum Torque Angle is for setting the phase difference between zero-sequence voltage and zero-sequence current, and the protection zone is between -90° and +90° on the basis of Maximum Torque Angle. And it can be used for alarm or Trip.

13.4 DIRECTIONAL BLOCKING Directional Blocking is a protection feature that restricts tripping on faults to a designated side of the recloser. It prevents nuisance tripping if particular network conditions are causing ‘False’ earth faults. In radial systems Directional Blocking prevents nuisance tripping by blocking faults in the reverse direction and only responding to faults in the foward direction. Protect for faults in the forward and reverse direction. A forward fault may use a different time-current curve and setting to a reverse fault (i.e. these are individually selectable). Both the forward protection and reverse protection are operating at the same time. This is an additional protection feature.

13.5 INRUSH RESTRAINTS Inrush Restraint works by raising the phase and earth currents for a short period of time to allow the inrush current to subside. Inrush current is an over-current higher than pickup current level, which is mainly caused by transformer’s excitation current at closing action. To distinguish inrush current from load current, 2nd harmonics percentage is adopted as a criterion. When, in the setting, ‘Fault Detection-Inrush Block’ is set to ‘Yes’ and ‘Fault Detection-Inrush Detection-Function In Use’ is set to ‘ON’, inrush current over pickup level is considered as normal load current and reclosing sequence is not processed. This Function can be used to detect magnetizing inrush condition by comparing 2nd harmonic component to fundamental frequency component of current.

14.2.2 SHORT-DURATION VOLTAGE VARIATION There are three types of short-duration voltage variations, namely, instantaneous, momentary and temporary, depending on its duration. Short-duration voltage variations are caused by fault conditions, energization of large loads, which require high starting currents or loose connections in power wiring. Depending on the fault location and the system conditions, the fault can generate sags, swells or interruptions. The fault condition can be close to or remote from the point of interest. During the actual


81

ISO 9001 certified


fault condition, the effect of the voltage is of short-duration variation until protective devices operate to clear the fault. 14.2.2.1 SAG A sag (also known as dip) is a reduction to between 0.5 and 0.99 pu in RMS voltage or current at the power frequency for a short period of time from 0.5 to 10 cycle. A 10% sag is considered an event during which the RMS voltage decreased by 10% to 0.9 pu. Voltage sags are widely recorgnized as among the most common and inportant aspects of power quality problems affecting industrial and commercial customers. They are particularly troublesome. Since they occur randomly and are difficult to predict. Volatge sags are normally associated with system faults on the distribution system, sudden increase in system loads, lightning strikes or starting of large load like induction motors. It is not possible to eliminate faults on a system. One of the most common causes of faults occuring on high-volatage transmission systems is a lightning strike. When there is a fault caused by a lightning strike, the voltage can sag to 50% of the standard range and can last from four to seven cycles. Most loads will be tripped off when encounter this type of voltage level. Possible effect of voltage sags would be system shutdown or reduce effciency and life span of electrical equipment, particularly motors. Equipment sensitivity to voltage sag occurs randomly and has become the most serious power quality problem affecting many industries and commercial customers presently. An industrial monitoring program determined an 87% voltage disturbances could be associate to voltage sags. Most of the fault on the utility transmission and distribution system are single line-to-ground faults (SLGF).

14.2.2.2 SWELL A swell (also known as momentary overvoltage) is an increase in RMS voltage or current at the power frequency to between 1.01 and 1.5 Pu for duration from 0.5 to 10 cycles. Swells are commonly caused by system conditions, switching off a large load or energizing a large capacitor bank. A swell can occur during a single line-to-ground fault (SLGF) with a temporary voltage rise on the unfaulted phases. They are not as common as voltage sags and are characterized also by both the magnitude and duration. During a fault condition, the severity of a voltage swell is very much dependent on the system

They are characterized by their duration as the voltage magnitude is always less than 10% of the nominal. The duration of an interruption can be irregular when due to equipment malfuctions or loose connections. The duration of an interruption due to a fault on the utility system is determined by the utility protective devices operating time.

15. STATUS MONITORING & CONTROL 15.1 SWITHCH CONTROL Recloser can be controlled from remote or local operator place. Operator place can be changed only at local front panel. ‘REMOTE CONTROL’ push button is to select the operator place. Operator place is toggled between local and remote by pushing button. LED is lit if remote position is selected. FTU-R200 begins with remote position at power-up. Control is allowed only at the position selected. Local switch control requires two-step operation. It’s for security of operation. ‘SELECT’ button should be pushed before ‘CLOSE’ or ‘OPEN’. SELECT LED is lit if SELECT operation is valid. SELECT can be canceled by pushing SELECT button again or automatically after SBO timeout without operation. CLOSE or OPEN operation is valid while this LED is lit. Pushing CLOSE or OPEN button outputs switch control signal with fixed time pulse which is configurable. Switch status change input which is auxiliary contacts of switch stops continuing to output pulse. There are some interlock conditions to inhibit FTU from outputting pulse signal. Gas low, Switch handle lock, same status of switch auxiliary contacts ‘a’, ‘b’ are those. Close or open pulse width shall be set longer than switch operating time. Remote switch control is possible by using SCADA protocol DNP3.0 or IEC60870-5-101, IEC60870-5-104 FTU-R200 supports SBO (Select Before Operate) or Direct operate. If the operator place is set to ‘Local’, remote control commands are refused. Pulse width of remote control command shorter than setting will be overridden by local configuration 15.2 SWITCH STATUS MONITORING FTU monitors switch open/close, gas and lock status through auxiliary contacts. FTU scans these contacts input every 5 milliseconds. Switch open/close status is determined by double binary input, normally open and closed contacts. Changes of all input status are saved as events with time tag in history buffer. For each contact input, on-delay time can be applied. It’s adjustable within 10~500ms by 5ms step.

15.3 BATTERY MONITORING FTU monitors external Lead-acid battery through the control unit, which are mounted on inner back-side of control box. Battery voltage is supervised continuously during external AC supply loss. If overdischarge condition occurred, the control unit sends alarm signal to RTU and disconnect battery in order


87

ISO 9001 certified


to protect battery cell damage after 1-minute delay. The delay enables RTU to send alarm state to remote station via communication. Also while AC supply is applied, battery test control activates this function with connecting dummy battery load during test pulse, which is configurable. The test control command can be ordered at local or remote.

16. MEASUREMENT 16.1 BASIC ELECTRIC QUANTITIES FTU has 3-phase currents and 6 voltages input. DSP digitizes these signals and calculates various electric quantities. These are basically based on fundamental frequency components. DSP use FFT (Fast Fourier Transform) algorithm to get the components. Also DSP calculates true RMS of 3-phase currents and voltages which include system frequency components and 2nd~31th harmonics. Actually harmonic components over than 31th are attenuated by analog filters. Electric quantities calculated are listed in the following. l

Currents (Ia, Ib, Ic, In)

RMS, Phase Angle, True RMS

l

Voltage (Va, Vb, Vc, Vr, Vs,

RMS, Phase Angle, True RMS

V t) l

Apparent Power


l

Active Power


l

Reactive Power


l

Power Factor


l

Va-Vr Phase Angle Difference

l

Current, Voltage Unbalance

l

Frequency, Temporature

In the above items listed, active power, reactive power values are signed integer. Sign represents power flow or if loads are inductive or capacitive. Also power factor has lead/lag state value separately. Currents and voltages have phase angles, which are relative phase angles compared to the reference Va. These angles are useful to monitor the phase sequence and imbalance of distribution line. 16.2 SEQUENCE COMPONENTS FTU provides the sequence components of 3-phase currents and voltages. They are positive sequence current (I1) and voltage (V1), negative sequence current (I2) and voltage (V2), and zero sequence voltage (V0) which are calculated by 3-phase phasor quantities. This information can be used to monitor imbalance of distribution line.


88

ISO 9001 certified


16.3 HARMONICS FTU extracts harmonic components from 3-phase current and voltage signals by using FFT (Fast Fourier Transform). It provides 2nd to 31st harmonic magnitudes and THDs (Total Harmonic Distortion) for each phase. THD is the total harmonic percentage to the fundamental frequency component. FTU also calculates and provides 3-phase THD. These values may be used to monitor the power quality of distribution line. 16.4 ENERGY FTU provides active energy, reactive energy for each phase or 3-phase total. Also import, export energy are accumulated on separate register. Units of energy are kWh, kVarh, which represent primary distribution line energy flow. The values are represented by 16-bit rollovers kWh, kVarh counters which are available at remote or local. Power calculation for energy is based on the fundamental frequency component. It’s not for billing purpose, but for load management. Proper energy accumulation needs that SCADA read energy counter with reset from FTU and accumulate it on SCADA’s local register by periods shorter than the expected rollover time of the counter.

[Four-quadrant power flow directions ] 16.5 DEMAND CURRENTS AND POWER FTU calculates and stores average of currents and active, reactive powers during the demand interval, which is configurable as 5, 10, or 15 minutes. The buffer has 1023 demands. Also FTU stores daily peak demand up to 1023.

Scale

The scale is used to multiply the reported analog value by the amount enterd. For example, scaling the I a RMS value by a multiple of ten will change the reported value from zero decimal points to one decimal point (i.e:9 to 9.0) Default Value: 1, Range: 1,10,100,1000

Deadband

Display the deadband value for the point. The analog point value must change by more than the deadband amount before it is reported.

19.2.7 COUNTER Counters are used to count data and events such as Trips, Protection Pickups, Faults and Accumulated kWh.

20. WAVEFORM EVALUATION TOOL 20.1 OVERVIEW The Waveform data upload from FTU-R200 through the above setting program are analyzed in this evaluation tool. Graphs of currents/voltages and operation of protection elements are displayed, and instantaneous/RMS current and voltage values, phase angles and time information at tracker position are presented. If 2 trackter one is moving with left mouse button and the other with right mouse button are used, time difference between two points is presented and it becomes the ruler for correct operation of protection element as setting. And, harmonics up to 31 st and THD (Total Harmonic Distortion) also show up. Recorded waveforms can be uploaded to FTUMan in local site. After uploading stored to the COMTRADE file format. These waveform data saved as COMTRADE file format and compatible with other analyzing tool. n

COMTRADE file

Comtrade (COMmon format for Transient Data Exchange for power systems) is a file format for oscilloscops data. It is used by many leading coñpanies for the oscilloscops used in high voltage substations. It has been standardised by the IEEE.
