If you need more information on how to choose suitable load control mode, please refer to the chapter
6.8.7 Managing system load control modes.
System load control modes are determined by setpoints
ProcessControl
:
Mload ctrl PtM
and
SysLdCtrl PtM
.
If
ProcessControl
:
#SysLdCtrl PtM
is set to BASELOAD, then Gen-set group requested load is not
determined by InteliMains but it is given by setpoint
ProcessControl:
#SysBaseLoad
regardless of
ProcessControl:
Mload ctrl PtM
setting.
