integrated power quality control system and power control method for one load

摘要

Integrated power quality control system and power control method for one load. It is an integrated power quality control system (60) including a transformer (62) with a primary winding (64), a secondary winding (66, 74) and a coiled compensating winding (68, 75). in a magnetic core (158). an electronic power converter (78) in the system provides a reference voltage to the compensation winding to inject a series voltage into the transformer secondary winding. A controller (80) is used to generate the reference voltage for the electronic power converter based on a power quality control requirement.
