Reduces The Harmonics And Losses By Using Control Technique Of VSI Based STATCOM

摘要

The Static Synchronous Co mpensator (STATCOM) is increasingly popular in power quality application. The Voltage Source Inverter (VSI) based STATCOM is used for eliminating current harmonics and compensating reactive power. This V SI draw or supply a compensating current fro m the utility such that it cancels current harmonics on the AC side. STATCOM generates a current wave such that it compensate by cancelling out the non-linear current waveform generateted by load. In this paper hysteresis controller based STATCOM is proposed. The STATCOM modeled using Simulink of MATLAB. Simula-tion result of 6 pulse VSI based STA TCOM validate current control strategy to prevent harmonics current and compensate reactive power
