method thereby dividing the network into sectors called power network areas. Each
PML630 is responsible for the load-shedding action in its respective area, based on the
power source capabilities and inter-power network area connectivity status. The
coordination of load-shedding actions between the PML630 IEDs is handled by
suitable parameterization. This arrangement of multiple PML630 IEDs in a peer-to-
peer method is called cPMS - LS configuration B.
The PML630 IEDs communicate with each other also using IEC 61850 GOOSE.
Likewise, cPMS - LS configuration B is also a feature in PML630. The Configuration
B is always built up over and above the Configuration A and hence the latter is a
prerequisite.
The maximum recommended number of PML630 IEDs in a peer-to-peer mode in
Configuration B is three.
The power network areas would be connected to each other through their grid 1 or grid
2 power source connection points.

Support for Relion
620 series, RIO600 in the solution cluster
Fast load-shedding: external trigger enabling, extending network
capability with Configuration B
Slow load-shedding: coverage of all 6 generators for current-based
overload load-shedding, 2 grid transformers' currents can be directly
monitored for overcurrent using 8 CT TRM card; provision for direct
reduction of overload (in addition to power-balance calculations)
Manual load-shedding: defining load-shedding by power value from
LHMI/COM600, external trigger for all 4 subnetworks
Underfrequency load-shedding using 630 series' Multipurpose analog
protection MAPGAPC for underfrequency detection and activation
through fast and slow load-shedding functions
Manual load-shedding mode not affected when fast and slow load-
shedding modes are blocked
Provision for external inhibition of load feeders
Adaptation for double-busbar configuration
