Interlocking
To derive the signals:
BC_AB_CL
Signal if an other bus-coupler connection exists between busbar A and B.
VP_BC_AB
The switch status of BC_AB is valid.
EXDUP_BC
Signal if there is no transmission error from bay BC (bus-coupler bay).
These signals from each bus-coupler bay (ABC_BC), except the own bay
are needed:
BCABCLTR
Signal if a bus-coupler connection through the own bus coupler exists
between busbar A and B.
VPBCABTR
The switch status of BC_AB is valid.
EXDUP_BC
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 disconnector A1A2_DC and B1B2_DC.
DCCLTR
Signal if the bus-section disconnector is closed.
VPDCTR
The switch status of A1A2_DC is valid.
EXDUP_DC
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.
If the busbar is divided by bus-section circuit breakers, the signals from
the bus-section coupler bay (A1A2_BS), rather than the bus-section dis-
connector bay (A1A2_DC), must be used. For B1B2_BS, corresponding
signals from busbar B are used. The same type of module (A1A2_BS) is
used for different busbars, that is, for both bus-section circuit breakers
A1A2_BS and B1B2_BS.
