Three Phases Fault Analysis in Transmission Line Using UPFC

Abstract

In this paper analyse well regulated power flow between the Bus systems so as to maximize the power quality by minimizing the losses and improving the power transfer capability of system by use of FACTS devices. Regulating flow of active and reactive power and hence power factor of line allows the system to be utilized to full potential. It is often observed that due to losses in power systems there is an underutilization of available resources, and to overcome those drawbacks compensators are used such as Series and Shunt compensators. Series and shunt compensation although have good performance on their relevant conditions but have certain drawbacks with the regulation of power flow and also the size, so by combining the features of series compensator and shunt compensator a novel approach is developed named UPFC which allows the power exchange between the compensators via DC link. Which is further discussed in the paper .The entire system is designed and analysed using
