Performance of Indirectly Controlled STATCOM with IEEE 30-bus System

STATCOM is one of the Flexible AC Transmission System (FACTS) devices primarily used for reactive power compensation in power system and also for improvement of voltage profile in the system. In this article a CMLI based indirectly controlled STATCOM has been placed in IEEE30-bus system for its performance evaluation in regulating the voltages of different buses and also its capability to operate under fault condition of power system. The whole systems i.e. STATCOM and IEEE 30-bus system are simulated on MATLAB Simulink environment using SimPower Systems Block Sets. Simulation studies have been carried out under load variations at different buses and its operation under fault conditions. It has been found from the simulation studies that it works well in maintaining bus voltages and it also supports system bus voltages under fault conditions.
