Reactive power control

Reactive power can be used in electrical energy supply networks to bolster the level of voltage. As such, feed-in
inverters can contribute to statistical voltage stability. Reactive power brings about a voltage drop at the induc-
tive and capacitive components of the equipment which can either bolster or reduce the level of voltage. If the
generating plant draws inductive reactive power while active power is being fed in, part of the voltage swing
caused by the active power feed can be compensated for by the supply of reactive power.
This reactive power mode and the respective control process are specified by the grid operator. If no control
process has been specified, then the plant should be operated using a reactive power specification of 0%.
10.1.1 Operating power range depending on grid voltage
The device can be operated within the respective fixed voltage range provided. The maximum apparent power
is stated in the following table. In the event of undervoltage determined by the maximum continuous current
subject to the grid voltage.
The following figures show the reactive power operating range as a function of the active power and the appar-
ent power operating range as a function of the mains voltage for various units.
