Reactive power control with CosPhi(P) characteristic curve

A CosPhi(P) characteristic curve has been implemented as an extension to the Q(P) characteristic curve of the VDE and EN standards. The parameters of the ReactiveByActive group apply. (see ReactiveByActive).

Setting eReactiveMode = ByActiveCosPhi activates the CosPhi(P) characteristic curve for reactive power control. This is configured in the same way as Q(P) via the lookup table ReactiveByActiveCosPhiPoints. Hysteresis is implemented via the parameters ReactiveByActiveStrVoltage, ReactiveByActiveStpVoltage. The resulting characteristic curve with the parameters used is shown in the following figure.
