Abstract: This paper deals with the reactive power compensation and better mitigation of transmission related problems in today’s world for a profound reliability of the offered power quality. we look at the FACTS controller being used for both series and shunt compensation. In that study shunt operation of the STATCOM and its principles of operation, control and how it helps in the better utilization of a network operating under normal conditions. A control system was developed to compensate unbalance reactive power and it was simulated using MATLAB. Simulation results confirm that the STATCOM compensates unbalance reactive power at the load.
