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 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.
