Abstract

Power quality is a major concern considering weak bus systems. In order to improve power quality, residential consumers go with voltage stabilizers as a cheap solution consequently overstressing weak busses. Industrial consumers use other alternatives like switched capacitor banks to cope with low power factor but the limitation is step-wise reactive power injection which does not meet the changing load requirements. Real time improvement requires constant monitoring and real-time injection of Volt-Ampere-Reactive (VAR) which is possible with the help of a Static VAR Compensator (SVC). An SVC based Power Quality Improvement (PQI) is proposed in this paper which addresses the real time varying reactive VAR requirement with reduced harmonic content.
