A novel hysteresis control technique of VSI based STATCOM

The Static Synchronous Compensator (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 VSI draw or supply a compensating current from 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 generated by load. In this paper hysteresis controller based STATCOM is proposed. The STATCOM modeled using Simulink of MATLAB. Simulation result of 6 pulse VSI based STATCOM validate current control strategy to prevent harmonics current and compensate reactive power.
