The first current and voltage phase in the group signals will be used as reference and
the amplitude and angle compensation will be used for related input signals.
Analog outputs (Monitored data) from the function can be used for service values or
in the disturbance report. The active power is provided as MW value: P, or in percent
of base power: PPERCENT. The reactive power is provided as Mvar value: Q, or in
percent of base power: QPERCENT.
