Measures For Voltage Support Through Parameterization Of Reactive Power/Voltage Characteristic Curve: Varctlvolhystdb Mode - SMA MEDIUM VOLTAGE POWER STATION 500SC-JP System Manual

13 Function Description
The reactive power is set as a function of the grid voltage. The reactive power setpoint is adjusted in stages.
Figure 70: Characteristic curve for reducing reactive power as a function of the grid voltage
If the grid voltage is changed by the configurable voltage difference Q-VDif for the configurable duration of Q-
VDifTm, the reactive power setpoint will be adjusted by the value Q‑VArGra. The parameterization of this function
refers to the medium voltage.
