• All conditions for processing the must-shedding status hold good.
• The overcurrent operate status for power source 1, that is, OC_OPR_SRC1 is
FALSE.
• The maximum demand operate status for power source 1, that is,
MAX_DMD_SRC1 is FALSE.
• The external slow load-shed trigger for power source 1, that is, EXT_SLT_SRC1
is FALSE.
If any of the above conditions is not satisfied, the power balance status is FALSE.
The logic is identical for processing the PPLS2_DATA input and its
power balance status and must-shedding status.
The processed inputs PPLS1_DATA and PPLS2_DATA are provided as
PEER1_DATA and PEER2_DATA respectively.
corresponding signal name for PEER1_DATA and PEER2_DATA.

The module provides the PEER1_DATA and PEER2_DATA to Source1/source2 LS
data handle module, Power monitoring module and Load shedding sharing mode
logic module.

Source1/source2 LS data handle

Based on the different conditions, the module calculates the compensated circuit
breaker status, island parallel status, fast load-shedding blocking status, circuit
breaker blocking status and fast load-shedding trigger for power source 1 and power
source 2.
