The power transmission network and its effective utilization are the recent topic of interest. Flexible AC Transmission Systems (FACTS) devices are equipped in the transmission lines for control of real and reactive power flow. The reactive power compensation can be done with STATic COMpensator (STATCOM). The appropriate amount of reactive power generated by the STATCOM will improve voltage stability in the buses. The Non Linear Controller namely Feedback Linearization Controller (FBLC) is used for controlling the Voltage Source Converter of STATCOM. The closed loop control of STATCOM with FBLC using MATLAB/SIMULINK is described in this paper. The results shows that with the proposed controller, DC link capacitor voltage and AC coupling voltage of STATCOM are attained its desired value. The load flow analysis with STATCOM in IEEE 5 bus system shows that losses in the network are reduced and thus transmission efficiency is improved.
