Abstract
A mains voltage at a network node is statically and dynamically supported with a static power factor correction device which has a transformer and a self-commutated converter with at least one capacitive energy store. Instantaneous reference setpoint values for an underlying, secondary instantaneous control method are continuously determined as a function of determined voltage magnitude deviation of the mains voltage at the network node. The secondary instantaneous control method determines a phase angle as a function of determined instantaneous actual values. The phase angle defines the angle of the converter voltage space vector of the self-commutated converter as a function of the angle of the mains voltage space vector. This results in dynamic regulation of the reactive powers required for mains voltage regulation.
