Power monitoring
This module calculates the available power and active power of the power source. It
also calculates the governor mode of the generator.
The units of the
POWER
and
MAX_POWER
inputs can be W, kW or MW. This module
converts the units of the
POWER
and
MAX_POWER
inputs in kW as the
Power
convention
setting.
The
POWER
and
MAX_POWER
inputs must have the same unit.
