5.1 Default Settings
5.1.1 Selecting the Control Modes for Reactive Power Provision
Reactive power references can either be given as a direct reference for reactive power (Q) or as an indirect reference
via the power factor (PF). The references are based on the following control modes (setting options), can be set with
the number 1 to 9 in the parameter ModeSelect.
Parameter name Setting option Explanation
ModeSelect 1 Q(U) - Reactive Power as a Function of Grid Voltage
2 Q(P) - Reactive Power as a Function of Active Power
3 Q(S) - Reactive power as a function of apparent power
4 Control mode is in implementation phase
5 Q(ext) - Reactive power as a function of an external setpoint (default)
6 PF(U) - Power Factor as a Function of Grid Voltage
7 PF(P) - Power Factor as a Function of Active Power
8 Control mode is in implementation phase
9 PF(ext) - Power factor as a function of an external setpoint
