Figure 153:
Calculation of fast load-shed trigger signal for subnetworks
The module counts the number of times the fast load-shedding trigger signal is
generated and the
FLS_COUNTER
(fast load-shedding counter) output provides the
count. The
FLS_COUNTER
output can be reset through the
FLS_CNT_RST
(fast
load-shedding counter reset) input. The
FLS_COUNTER
output is provided in the
monitoring view.
The module receives the slow load-shed trigger signals,
SLS_TRG_BB1...SLS_TRG_BB4
, for busbar 1...4 from NPMMXU function. If
any of the busbar slow load-shed trigger signal is active, slow load-shed action is
initiated in corresponding subnetwork.
shows slow load-shed trigger signals for different subnetworks for various
conditions.
