Method for stabilizing an AC network against fluctuations in reactive load and reactive power compensation device

摘要

The method involves regulating the current through the load (8) to a defined demand value with a current regulator (16) in a control loop contg. the load as a control path and a current rectifier (5,5'). A current rectifier control value is formed depending on a current regulator control parameter produced by the current regulator. The reactive wattless power (Qx) of the load is regulated to a defined demand value depending on a stabilisation ignition angle of a reactive power regulator (22). The current rectifier control value is formed depending on a stabilisation ignition value multiplied by at least one predefined factor (K1,K3).
