Abstract

Reactive Power Compensation is an important and indispensable aspect in power system. Most of the loads are inductive in nature and consume reactive power. Hence, the distribution system behaves as the sink of reactive power. When the large amount of lagging current flows through the system, the system voltage goes down. In such situation, VAR compensator brings the voltage back to normal value. STATCOM is a FACTS device based on VSI topology, which generally provides superior performance characteristics compared to conventional compensation methods employing TSCs and TCRs. STATCOM can both supply and consume reactive power. When the system needs reactive power, it acts as a source and supplies reactive power but when there is excess of reactive power in the system, it acts as a sink and consumes reactive power. This paper presents MATLAB simulation of three phase STATCOM. A STATCOM with the Hysteresis Band Current Control is developed in MATLAB/Simulink to observe their performance.
