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 inductive and capacitive
components of the equipment which can either bolster or reduce the level of voltage. If the generating plant draws induc-
tive 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 volt-
age.
The following figures show the reactive power operating range subject to active power and the apparent power operating
range subject to the grid voltage for various devices.
