2.2 SUPPLY SECURITY LEVEL Supply security of a distribution system network defines the availability of supply to consumers following the occurrence of supply interruption. Systems and necessary network management infrastructure may be designed to meet any of the standardized security level definitions currently adopted by TNB as indicated in table 2-3.


2.2.1

Adopted Security Level Definitions For TNB Distribution Systems Table 2-3: Security Levels for Distribution Network

Security Level

Average Restoration Period

Level 1

Less than 5 seconds

Level 2

Less than 15 minutes

Level 3

Less than 4 hours

Level 4

Less than 24 hours

2.2.2 Supply Security Level to Consumers For supplies to consumers at voltage levels of 6.6kV, 11kV, 22kV and 33kV, large part of the network are generally designed to facilitate an average supply restoration of less than 4 hours. For supplies at 240V and 415V, the restoration period may vary beyond 4 hours depending on the type of network fault. 2.2.3 Request for Higher Supply Security Level However, TNB can design the supply scheme to meet higher security level requirement of individual consumer or group of consumers. All additional costs involved in providing the higher security level shall be borne by the consumer. 2.3 2.3.1

POWER QUALITY Power Quality Requirements

2.3.1.1 The electromagnetic disturbance covers the following phenomena: a. Voltage fluctuations and flickers b. Harmonics up to order of 50th c. Voltage dips and short supply interruptions d. Voltage unbalance e. Inter-harmonics up to 50th f. Voltage distortions at higher frequencies (above 50th harmonics) g. Transient overvoltages h. Power frequency variation i. Dc components j. Mains signaling

30


For the purpose of this guideline, Power Quality is defined as the degree to which the voltage at the point of connection to the consumer of the Distribution Network is maintained to be Sinusoidal at Rated Voltage Magnitude and Frequency. In this guideline only items a to d are considered. 2.3.1.2 This section specifies the Power Quality requirements of the electricity supply to be delivered to the consumers in the TNB distribution system in terms of voltage and frequency to be within specific limits so that the consumer s’ equipment directly connected to the TNB distribution system can operate safely within its design performance without suffering undue damage or breakdown. Likewise this guidelines shall be complied with by all consumers connected and who intend to be connected to the TNB distribution system. 2.3.1.3 In order to achieve the required Power Quality, these guidelines will be used by TNB in planning, developing, maintaining and operating the distribution system and in connecting Distributed Generation and Demand to the distribution system. 2.3.1.4 In cases where, the nature and operation of the new types of plant and equipment to be connected to the distribution system is perceived to be likely to cause problems to customers connected to the System, but not fully covered by this guidelines, expert advice will be sought to ensure the appropriate remedial measures are put in place.

2.3.2

Scope

2.3.2.1 This guidelines covers most of the power quality related phenomena generated by various types of plant and equipment connected to the distribution system as well as those generated by the transmission system. In each particular case the Distribution Power Quality that should be maintained is indicated together with the remedial approach and responsibilities of parties.

2.3.3

Voltage Dips/Sags

2.3.3.1 This guidelines does not specifically cover the requirements for transient phenomena which can affect the voltage level known as voltage “dip” or “sag” and “swell” usually experienced during system faults and the subsequent recovery period, which can adversely affect some customer equipment sensitive to such changes. Currently, there is no local or international guidelines that has been established to specify requirements of the supply voltage to the consumers with respect to the magnitude and duration of voltage dips and swells.


2.3.3.2 Guidelines and guides that exist with respect to voltage dips and swell are those that describe the environment in which the sensitive voltage equipment may experience which include typical number of voltage sag experiences and their duration. The main purpose of such guidelines is to ensure that equipment designed to be connected to the distribution systems to be compatible with the supply voltage performance in terms of various power quality problems including voltage sags. 2.3.3.3 �� Malaysian Standard MS 1760:2004 “Guides on Voltage Dips and Short Interruptions on Public Electric Power Supply Systems” contains definitions and descriptions of voltage sags and short interruptions. MS1760:2004 is based on IEC 61000-2-8 with some limited data on the characteristics for Malaysia. The purpose of the Guides is to discuss voltage dips and short interruptions primarily as phenomena observed on public supply systems and its effects on voltage sensitive equipment receiving supply from such systems. 2.3.3.4 There exist standards on immunity of equipment to supply voltage fluctuations and distortion with defined magnitude and duration of voltage dips and harmonics. IEC 61000-2 series of guidelines set out the supply characteristics e.g. IEC 61000-2.8 as indicated above. IEC 61000-3 series of guidelines sets out the compatibility levels which should be achieved when designing electrical equipment which may give rise to voltage fluctuations and harmonic distortion and when connecting such equipment to the distribution system, which will give immunity to interference to similar equipment connected to the distribution system. MS IEC 61000-4-11 & MS IEC 61000-4-34 series of standards specifies test methods. 2.3.3.5 Some equipment suppliers and trade organisations also specify the immunity levels for certain types of equipment for example Semiconductor Industry Guidelines SEMI F47, Computer and Business Equipment Manufacturing Association CBEMA Compatibility Guidelines. 2.3.3.6 TNB shall upon request from any customer advise the consumer having connected voltage sensitive loads or intending to connect voltage sensitive loads in their installation to take into account the short duration electromagnetic disturbance phenomena for selecting equipment with proper maximum intrinsic immunity.

2.3.4

Voltage Step Change

2.3.4.1 Limits of voltage changes due to Load, frequent and infrequent operational switching of Load both by TNB and the consumer are defined table �� 2.3.4.1. These limits are based on UK’s Engineering Recommendation P28 on �� “Planning Limits for Voltage Fluctuations Caused by Industrial, Commercial and Domestic Equipment in the United Kingdom”, 1989.

32


Table 2.3.4.1: Voltage limits on switching of load Load Starting/Switching

2.3.5

Limit of Voltage Change

Starting/switching once or twice a year

6%

Infrequent single starting/switching or disconnection of Load – once in two hours or more hours. Including capacitor or reactor bank

3%

Frequent starting/switching and/or disconnection of Load (e.g., Many times in a day)

1%

Voltage Fluctuations and Flicker

2.3.5.�� 1 The limits of Flicker that are acceptable on the distribution system are in accordance with the “Engineering Recommendation P28, Issued by The Electricity Council of UK in 1989 entitled Planning Limits for Voltage Fluctuation Caused by Industrial, Commercial and Domestic Equipment in the United Kingdom”. TNB uses the procedures contained in this document to plan the connection of Fluctuating Loads and applies the limits therein in measuring and monitoring the levels of Flicker at such points of connection. 2.3.5�� .2 In accordance with the “Engineering �� Recommendation P28”, voltage fluctuations at a Point of Common Coupling with a fluctuating Load directly connected to the Distribution System shall not exceed: (a) 1% of the voltage level for step changes, which may occur repetitively. Any large voltage excursions other than step changes or less frequent step changes may be allowed up to a level of 3% provided that this does not constitute a risk to the distribution system or, in TNB’s�� view, any other party connected to the distribution system. (b) The planning limits for the Short and Long Term Flicker Severity applicable for Fluctuating Loads connected to the distribution system are as set out in the table below.


Table 2.3.5.2 : Maximum allowable flicker severity TNB distribution system Voltage Level at which the Fluctuating Load is Connected

Absolute Short Term Flicker Severity (Pst)

Absolute Long Term Flicker Severity (Plt)

500, 275 and 132kV

1.0

0.8

Less than 132kV

0.8

0.6

2.3.5.3 In connecting a Fluctuating Load at a particular point or Point of Common Coupling it is necessary to assess the total Flicker due to the Fluctuating Load itself and the background Flicker measured at that point. In assessing the total Flicker TNB shall use the so called “RSS Rule”. This assessment is carried out by the RSS Rule by obtaining the sum of the squares of the Flicker from the Fluctuating Load and the background Flicker, with the square root of this sum yielding the total assessed Flicker at that Point of Common Coupling due to the specific Fluctuating Load and the background Flicker at that point.

2.3.5.4 Connection of more than one Fluctuating Load at the same Point of Common Coupling or addition of further Fluctuating Load at the same location is carried out on a “first come first served” basis on the distribution system. This means that whilst the first Fluctuating Load may be within the allowable Flicker limits and not require any Flicker mitigation or compensation equipment, the second Fluctuating Load which may cause violation of Flicker limits will be obliged to invest in appropriate Flicker mitigation or compensation equipment. At the planning stage, in carrying out the assessment of the total Flicker due to more than one Fluctuating Load connecting at a particular Points of Common Coupling, TNB shall use the methodology described in P28.

2.3.5.5 In assessing the level of Flicker due to a Fluctuating Load at the planning stage the assessment will be carried out at a realistic System operating condition giving the minimum number of connections with which that point on the System can be operated within normal voltage limits and following Secured Contingency Events. This condition shall be considered as representative of the type of System conditions under which the Flicker due to a Fluctuating Load will be at its highest value as the voltage fluctuations due to the Fluctuating Load will be at their highest level under such conditions.

34


2.3.5.6 If under the operating conditions described in 2.3.5.5 the Flicker due to a Fluctuating Load exceeds the limits then Flicker compensation, which will reduce the Flicker to an acceptable level shall be installed. For the avoidance of doubt the acceptance Criteria for Flicker is the 95% values of Short and Long Term Flicker Severity i.e., Pst and Plt will be below the limits specified in table 2.3.5.2. Here the 95% values mean the values of Flicker Severity measured and observed during 95% of the total observation period. The System overall performance yardstick for the level of Flicker reduction to be achieved shall be based upon enabling connection of other similar Fluctuating Load and/or permitting for future extension and development of the location with further Fluctuating Load installations. The Flicker compensation method and equipment to be used shall be of a type that does not cause resonance problems with the existing and intended future developments of the distribution system. 2.3.5.7 If the permissible Flicker limits cannot be met even with installation of Flicker compensation at a particular Points of Common Coupling at a particular System voltage level then connection of the Fluctuating Load at a higher voltage level or elsewhere in the System shall be considered. The connection point of choice will need to have to experience lower voltage fluctuations than the first connection point considered under the operational conditions in 2.3.5.5.

2.3.6

Harmonics

2.3.6.1 All plant and equipment connected to the Distribution System, and that part of the TNB distribution system at each connection site, should be capable of withstanding the following distortions of the voltage waveform in respect of harmonic content. The maximum total levels of Harmonic Distortion at any connection point on the distribution system from all sources under both planned outage and Secured Contingency Event conditions, unless abnormal conditions prevail, shall not exceed: (a) at 33kV and 22kV, a Total Harmonic Distortion of 3% with no individual harmonic voltage greater than that shown in the tables X; (b) at 11kV and 6.6kV, a Total Harmonic Distortion of 4% with no individual harmonic voltage greater than that shown in the tables Y; (c) at 415V and below, a Total Harmonic Distortion of 5% with no individual harmonic voltage greater than that shown in the tables Z; (d) infrequent short duration peaks may be permitted by �� TNB�� to exceed the above levels for harmonic distortion;


2.3.6�� .2 A Consumer who intends to connect non-linear loads to the TNB system shall carry out assessment �� harmonic distortion levels for the connection of each non-linear Load to the Distribution System. TNB will verify the results of the assessments.

2.3.6�� .3 Consumers shall ensure that the Immunity Level of their plant and Apparatus is compatible with the electromagnetic disturbances present on the System including harmonics.

2.3.6�� .4 In assessing the level of harmonic distortion and individual harmonic levels at the planning stage, the assessment will be carried out at a realistic system operating condition giving the minimum number of connections with which that point on the system can be operated within normal voltage limits and following secured contingency events. This condition shall be considered as representative of the type of system conditions under which the harmonic distortion and individual harmonic levels will be at their highest level.

2.3.6�� .5 If under the operating conditions describes in 2.3.6.1 (a) the harmonic distortion and individual harmonic levels due to the load exceed the limits then harmonic filters which will reduce the harmonics to an acceptable level shall be installed to bring the levels within limits. The system overall performance yardstick for the level of harmonic reduction to be achieved shall be based upon enabling connection of other similar harmonic producing load and/or permitting for future extension and development of the location with further harmonic producing load installations.

2.3.6�� .6 The planning limits of harmonics that are acceptable of the distribution system are in accordance with MS IEC 61000-3-6 “ Assessment of emission limits for distorting loads in MV & HV power systems”, and where appropriate Engineering Recommendations G5/4 is adopted.

2.3.6�� .7 TNB uses the procedures contained in this document to plan the connection of loads producing harmonics and applies the limits therein in measuring and monitoring the levels of harmonics at such points of connection. These are given in summary in the tables below.

The total voltage harmonic distortion level is 5% Note: The above table shows the Engineering Recommendation G5/4 levels. TNB is in the process of adopting IEC levels and the values in the above table will be updated later

2.3.7 Voltage Unbalance 2.3.7.1 All plant and equipment connected to the distribution system, and that part of the distribution system at each connection site, should be capable of withstanding the following distortions of the voltage waveform in respect of Voltage Unbalance at the planning stage. 1) Under planned outage conditions, the maximum negative phase sequence component of the phase voltage on the distribution system should remain below 1% unless abnormal conditions prevail. 2) Under the planned outage conditions, infrequent short duration peaks with a maximum value of 2% are permitted for Voltage Unbalance, subject to the prior agreement of �� TNB�� under the connection agreement. TNB�� will only agree following a specific assessment of the impact of these levels on �� TNB�� and other Customers’ plant and equipment with which it is satisfied.

38


3) At the terminals of a Customer’s installation or specific Load the Voltage Unbalance voltage shall not exceed 1% for 5 occasions within any 30 minute time period. 4) In terms of traction Loads connected to the distribution system the acceptable limits of Voltage Unbalance are in accordance with “Engineering Recommendation (E/R) P29, issued by the Electricity Council of UK in 1984 entitled “AC Traction Supplies to British Rail” and its successor document P 29 issued in 1990 “Planning Limits for Voltage Unbalance in the United Kingdom”. TNB uses the procedures contained in this document to plan the connection of Loads producing Voltage Unbalance and applies the limits therein in measuring and monitoring the levels of unbalance at such points of connection. 2.3.7.2 In assessing level of Voltage Unbalance at the planning stage the assessment will be carried out at a realistic System operating condition giving the minimum number of connections with which that point on the System can be operated within normal voltage limits with maintenance outages and following Secured Contingency Events. This condition shall be considered as representative of the type of System conditions under which the Voltage Unbalance will be at its highest value.

2.3.7.3 If under the operating conditions described earlier the Voltage Unbalance due to the Load exceeds the limits then balancing compensation equipment, which will reduce the unbalance to an acceptable level shall be installed to bring the levels within the limits. The System overall performance yardstick for the level of unbalance reduction to be achieved shall be based upon enabling connection of other similar unbalance producing Load and/or permitting for future extension and development of the location with further unbalance producing Load installations. The balancing compensation equipment to be installed shall be of a type that does not cause resonance problems with the existing and intended future developments of the distribution system.

2.4 SHORT-CIRCUIT LEVELS TNB network are design and operated in order to remain within the limits of short-circuit levels as in Table 2-4. TNB equipment design are specified to the same S.C rating. Consumer equipment at the point of interface or part of the interconnection design shall also the minimum S.C rating. TNB may provide indicative or prospective fault level in terms of X/R ratio at the interface point with consumer, if so required for detailed installation design. Values in table 2-4 gives the maximum short-circuit level at the various voltage levels.

2.5 PROTECTION REQUIREMENTS 2.5.1 Basic Requirements In all cases, the basic requirement is that the consumer’s arrangements for protection at the connection point, including types of equipment and protection settings, must be compatible with standard practices on the TNB’s system, and be as TNB specifies during the application for supply process. This is especially critical for MV and HV consumers. 2.5.2 Specific Requirements Consumers shall take into consideration the following specific protection practices of TNB in designing their installation: (a)

Maximum clearance times (from fault current inception to fault clearing) must be within the limits established TNB in their short circuit rating policy for the distribution system.

(b)

Auto-reclosing or sequential switching features may be used on TNB’s distribution system. TNB will provide details on the operating sequence utilised for the supplies on the proposed installation so the consumer can plan for this in the design and protection of his facility.

(c)

On some of TNB’s distribution systems, certain types of faults may cause disconnection of one phase only of a three-phase supply.

40


2.5.3 Protection System Evaluation Process Consumer’s installation to supplied at 11kV and above shall provide the appropriate and matching protection scheme to support the desired operation of the designed supply scheme. The reliability of the equipment, protective devices and protection systems being deployed at the consumer connection or interface points may effect the reliability of TNB’s supply system.

SECTION 3.0: DEMAND ESTIMATION Supply schemes and networks are to be adequately designed or dimensioned to meet initial and growth of consumer individual and group maximum demand. The demand estimates are based upon load declared by consumer and TNB’s own information on load profile characteristics for various consumer classes. Range of values are given as demand profile are known to varies according to geographical location of consumers around the TNB service areas in Peninsular Malaysia. Fairly accurate assessment of individual and group demand of consumers are critical for correct dimensioning of network or facilities in meeting the initial and future demand of consumers as imposed on the network. 3.1 Demand Estimates For Consumer Sub-Classes Or Premises Table 3-1 and 3-2 indicates the typical ranges of maximum demand for domestic and shop-lots or shop-houses respectively. These values shall be subjected to revisions based upon of latest results load profiling studies. Table 3-1: Range of maximum demand (M.D) for domestic consumer sub-classes or premises

3.2 Group Diversity Group diversity is applied in the computation of unit demand and group demand. The typical values for diversity factors for various consumer classes is as in the table below. Table 3-3: Typical Group Diversity Values

Consumer classes Domestic Less than 10 consumers More than 10 consumers Commercial or industrial Less than 10 consumers More than 10 consumers

Group Diversity factors 0.80 0.75 0.80 0.75

3.3 Demand Estimates For A Mixed Development Area. Accurate determination of the maximum possible demand for a newly proposed development is critical in the effective long-term planning of supply network within the specific area. Adequate land areas for transmission main intakes (PMU 132/33kV, 132/22kV, 132/11kV), major distribution stations (PPU 33/11kV, 22/11kV), sub-stations (PE 11/. 415kV, 22/. 415kV), underground cable and overhead line routes will have to be allocated at the layout approval stage by the relevant authorities. The total demand will indicate the supply voltage and target network configuration for the whole development area. Network facilities will be developed in phases in tandem with physical development. Site selections for PMU, PPU, sub-stations and feeder routes are normally made to achieve optimal technical performance of network and costs based on the planned target network. Appendix 15 indicates the sample M.D worksheet for a mix development area to be filled up and submitted to TNB at the supply application stage. 3.4 Demand Projection And Substation Requirements For LV Scheme Demand projection of a new development area, say a proposed housing scheme, determines the number of sub-station requirements (11/. 415kV) in the design of low voltage system. Appendix 16 indicates the method for determining the overall numbers and capacity of sub-station for a typical housing or commercial scheme based upon the projected demand growth.


SECTION 4: SUPPLY SCHEMES Based upon consumer declared demand level and required security level, supply schemes to consumers are appropriately designed to meet these requirements and planning criteria as discussed in section 2. 4.1

Maximum Demand Levels And Supply Schemes

The table below indicates the typical schemes for various demand levels of individual consumers. In the case of maximum demand (M.D) ranges of 5MVA to 10MVA, the supply voltage options of either 11kV or 33kV will ultimately be determined by the predominant supply voltage where the prospective consumer is to be connected. Consumers with M.D approaching 1000kVA have the option of taking supply at 11kV. Table 4-1: Typical supply schemes for various M.D levels

Substation Categories, Type & Design Sub-station categories

a. Transmission Main Intake (Pencawang Masuk Utama-PMU) Transmission Main Intake is the interconnection point of 132kV or 275kV to the distribution network. The standard transmission capacity and voltage transformation provided at the PMU are as follows:-

44


- 132/33kV, 2 x 90 MVA - 132/22kV, 2 x 60 MVA - 132/11kV, 2 x 30 MVA

b. Main Distribution Sub-station (Pencawang Pembahagian Utama- PPU) Main Distribution Sub-station is normally applicable to 33kV for interconnecting 33kV networks with 11kV networks. It provides capacity injection into 11kV network through a standardized transformation of 33/11kV.

c. Main Switching Station (Stesyen Suis Utama- SSU) SSU at 33kV, 22kV and 11kV are established to serve the following function:1. To supply a dedicated bulk consumer ( 33kV, 22kV, 11kV) 2. To provide bulk capacity injection or transfer from a PMU/PPU to a load center for further localized distribution.

d. Distribution Substation (Pencawang Elektrik – P/E) Distribution sub-stations are capacity injection points from 11kV, 22kV and sometimes 33kV systems to the low voltage network (415V, 240V). Typical capacity ratings are 1000kVA, 750kVA, 500kVA and 300kVA. Conventional substation designs are of indoor type (equipment housed in a permanent building) and out-door type (ground-mounted or pole-mounted). Standardized M & E design of 11/. 433kV sub-station is available at TNB offices.

Compact substation (11/. 415kV) has limited application and is to be strictly applied in selective situations under the following circumstances:§ System reinforcement projects for highly built-up areas where substation land is difficult to acquire. § Any request to use compact substation for dedicated supply to a single or limited group of low voltage consumers is subject to TNB approval in accordance to site constraints situation, and to be considered as ‘special feature design schemes’.

The main reasons for the above application criteria are as follows:• Compact design reduces future system flexibility in terms of network expansion. • Compact design features, which limits the capacity of outgoing circuits.

(c) LLM (Malaysian Highway Authority): As requisitioned by LLM.

46


The establishment of transmission main intake also requires the allocation and acquisition of right of way or wayleaves for the transmission lines. Depending on the specific design of each PMU, the overall right of way or wayleaves requirements may be different. Developers of large-scale development areas, depending on the estimated demand may be required to allocate land for any or a combination of sub-stations categories, wayleaves or right of way for 132kV/275kV lines. These requirements will be specified by TNB upon submission of tentative layout plans and load estimates for the whole development area.

4.2.3

Type of fire fighting System for the Substation

Type of fire fighting system that is suitable for the substation has to meet the following criteria: • The fire extinguishing agent has to be the type that is approved by TNB.

4.3

Standard And Special Feature Design Schemes

Standard features of supply schemes are categorized as those typical design schemes for individual or consumer groups or classes. Typical cases are as follows:(i)

Supply scheme supplying domestic premises is predominantly through overhead systems and conventional substation. A fully underground network and any application of compact sub-station shall be considered as special features for which all extra costs incurred by TNB are to be paid in full by the consumer.

(ii)

Bulk consumers supplied at 11kV and above, are normally supplied via two in-feeds operating in parallel or nonparallel operation depending on the demand and security level required. If for any reason another dedicated cable is required purely for reasons of additional security, the extra costs shall have to be borne by the consumer.

4.4

Supply Schemes For Interconnection To Embedded Generators

Embedded generators depending on the capacity will be interconnected at 11kV and 33kV. The design of interconnection scheme or facilities, which may include protection, operational control facilities will be so determined to ensure safe, reliable and efficient interconnection scheme. The other design objective is to ensure that the interconnection of embedded generators should not negatively impact system performance and reliability to existing consumers connected to the TNB system.


All associated costs of network upgrading, which includes protection schemes, SCADA and communication facilities shall be borne by the owner of embedded generator seeking interconnection to the distribution network.
