• Digital Inputs Hardware Acquisition  

Each input is scanned cyclically by software scan period is fixed = 1 ms

Logic Checks  

Comparison of true states and of inverted states Verification of the address of the board

Time tagging  

At detection of the change of state Time quality depending on equipment synchronisation

Filtering    

Toggling (SPS,DPS,MPS) Persistence (SPS,DPS remaining in the same state during T time) Motion (DPS, not to take into account transients 00 and 11 states) Undefined MPS states (all inputs at state 0 or 1; more than 1 at state 1)


19

• Digital Inputs Transmission mode on the SBUS network Report based mode 

Change of status is spontaneously transmitted to the subscribers with the time stamping and the reason for change

GOOSE based mode 

Change of status is transmitted in multicast to the configured receivers. Only the BI unfiltered status is transmitted, the time stamp is not used and the reason for change is not transmitted.

Transmission to SCADA if connected


20

• Force, Suppress & Substitute (FSS) PROCESSING SUPPRESSION 

A Binary input is manually suppressed (It is not processed until unsuppression)

SUBSTITUTION 

The Binary input is substituted by an other state.

FORCING 

When a binary input becomes invalid , the operator can force it by a valid state. The binary input is automatically unforced when it becomes valid again.

AUTOMATIC FORCING 

A binary input is forced automatically to a valid state when it becomes invalid.


21

• Measurements ACQUISITION A measurement can be acquired using :  

an analogue input a digital measurement



IED : LBUS, SBUS a CT/VT input (or calculation => up to 184 values)



automation



PROCESSING A scaling law  

linear (single/multi slope) quadratic (square root)

Thresholds 

Up to 6 thresholds for which the detection caused by a measurement, variation can create an event or alarm.


22

• Measurements Transmission mode on the SBUS network Report based mode    

Periodically On variation On threshold violation On change of quality state

GOOSE based mode 

Change of value is transmitted in multicast to the configured receivers.

• Counters Digital Counters :  

Acquisition is stored to accumulators in non-volatile memory Accumulator is incremented at each valid counter pulse

IED Counters : 

transmitted cyclically are stored to the periodic register and FIFO memory

Operator can force the metering values. This modification can be a counter reset.

• Automatic Tap Change Control 

ATCC function is used to automatically maintain the correct voltage at the lower voltage of transformers



ATCC is able to manage one transformer or several transformers in parallel. Transformers are in parallel if their secondary poles are interconnected



ATCC is managed by one computer, receiving information from the others and sending control to them.
