The FACTS (Flexible AC Transmission Systems) is a modern technology, which is based on power electronic device controllers introduce by Dr. N.G. Hingorani. Since 1970s it has been used in power systems for enhancing the existing transmission capabilities and improvement in system dynamic performance in order to make the transmission line system flexible and efficient in operation. This paper deals with the simulation of complex (series-shunt) FACTS controllers. For this a Single Machine Infinite Bus (SMIB) system is modeled in matlab simulation. In this paper, simple circuit models of Unified Power Flow Controller (UPFC) and Interline power flow controller (IPFC) has been presented for both open loop and close loop configuration. For open loop configuration SPWM control strategy and for close loop system PID controller is used. The simulation results has been compared for both UPFC and IPFC in open loop and close loop system which demonstrates the performance of the SMIB system after compensating the system using the above-mentioned FACTS devices. This gives the clear observation of how the FACTS devices improve the voltage stability and thereby power profile of the power system. The FFT (fast fourier transform) analysis for both devices in open loop and close loop has been done for analyzing the THD (total harmonic distortion) level of the system. All simulations and analysis have been carried out in MATLAB12a/SIMULINK environment.
