AUTOMATIC AC BUS VOLTAGE REGULATION FOR POWER DISTRIBUTION GRIDS

摘要

A system for automatically regulating voltage on a distribution-level AC bus having an actual voltage and a nominal voltage includes an electronic power converter connected to the distribution-level AC bus. The system generates a feedback signal representative of the actual voltage of the distribution-level AC bus and produces an input control signal in response to the feedback signal. The input control signal is representative of a commanded level of reactive power. The electronic power converter is responsive to the input control signal to deliver a commanded reactive power output to the distribution-level AC bus, and the commanded reactive power output pushes the actual voltage towards the nominal voltage.
