To derive the signals:
ABCDC_OP
Signal if all disconnectors of this busbar section are open.
VP_ABCDC
The switch status of ABCDC is valid.
EXDUP_BB
Signal if no transmission error from any bay containing the above infor-
mation.
These signals from each line bay (ABC_LINE), each transformer bay
(AB_TRAFO), and each bus-coupler bay (ABC_BC) are needed:
Q1OPTR
Signal if Q1 is open.
Q2OPTR
Signal if Q2 (AB_TRAFO, ABC_LINE) is open.
Q20OPTR
Signal if Q2 and Q20 (ABC_BC) are open.
Q7OPTR
Signal if Q7 is open.
VPQ1TR
The switch status of Q1 is valid.
VPQ2TR
The switch status of Q2 is valid.
VPQ20TR
The switch status of Q2 and Q20 are valid.
VPQ7TR
The switch status of Q7 is valid.
EXDUP_BB
Signal if there is no transmission error from the bay that contains the
above information.This signal is taken from the data valid output on the
command function block.
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.
DCOPTR
Signal if the bus-section disconnector is open.
VPDCTR
The switch status of A1A2_DC is valid.
