In this paper a novel configuration employing multistage two-leg three phase converters for UPFC is proposed. The switching level modeling of UPFC is carried out using IGBT based shunt and series converters. The proposed converter has the capability of delivering sinusoidal input current with unity power factor and bidirectional power flow. The operating performance of UPFC is demonstrated on Single Machine Infinite Bus (SMIB) system and IEEE 14 Bus system for different load conditions. The real and reactive power tracings through the transmission lines in the system are obtained. The simulation study is carried out in a MATLAB/SIMULINK environment. The proposed topology effectively controls the real and reactive power flow in the transmission lines. This model considerably improves the system stability by damping the oscillation during the vulnerable conditions.
