HYBRID REACTIVE POWER CONTROL, APPLYING STATIC AND DYNAMIC COMPENSATION SCHEMES TO A STEEL PLANT

Abstract

This report presents the implementation of hybrid reactive power control employing static and dynamic compensation schemes in a modernization and expansion Project of a steel plant power facility. The scheme studies existing network reactive power behaviour and that of incoming loads to effect a design applying synchronous phase advancer for an alogue reactive power control to loads of matching reactive power profile and stepped capacitive reactive power control to others adaptive to it. In the end, a high efficient and a cost optimized reactive power scheme is adopted with release of up to 10.73% of existing system capacity for additional loading.
