Reactive power compensation in electrical power system

摘要

A reactive power compensation system for compensating reactive power requirements in an electrical power system. The reactive power compensation system includes a static synchronous compensation unit, a current harmonics elimination unit, and a compensation control unit. The static synchronous compensation unit includes a plurality of static synchronous compensation modules for compensating reactive power in the electrical power system. The current harmonics elimination unit includes a plurality of active filter modules for eliminating current harmonics generated in the electrical power system. The compensation control unit implements a sequential control mechanism for regulating the operation of the static synchronous compensation modules and the active filter modules.
