Figure 266: Busbars divided by bus-section disconnectors (circuit breakers)
To derive the signals:
Signal
BB_DC_OP All disconnectors on this part of the busbar are open.
VP_BB_DC The switch status of all disconnector on this part of the busbar is valid.
EXDU_BB No transmission error from any bay containing the above information.
These signals from each line bay (ABC_LINE), each transformer bay (AB_TRAFO),
and each bus-coupler bay (ABC_BC) are needed:
Signal
189OPTR 189 is open.
289OPTR 289 is open (AB_TRAFO, ABC_LINE)
22089OTR 289 and 2089 are open (ABC_BC)
789OPTR 789 is open.
VP189TR The switch status of 189 is valid.
VP289TR The switch status of 289 is valid.
V22089TR The switch status of 289and 2089 is valid.
VP789TR The switch status of 789 is valid.
EXDU_BB No transmission error from the bay that contains the above information.
These signals from each bus-section disconnector bay (A1A2_DC) are also needed.
For B1B2_DC, corresponding signals from busbar B are used. The same type of
module (A1A2_DC) is used for different busbars, that is, for both bus-section
disconnectors A1A2_DC and B1B2_DC.
Signal
DCOPTR The bus-section disconnector is open.
VPDCTR The switch status of bus-section disconnector DC is valid.
EXDU_DC No transmission error from the bay that contains the above information.
