Case Study on Power Quality Improvement of Thirty Bus System with UPFC

Abstract

Abstract-The unified power flow controller (UPFC) is a pair of back to back power electronic inverters which controls the real and reactive power flow in a transmission line. This paper describes the modeling and simulation of IEEE 30 bus system employing UPFC. Simulink models are developed for IEEE 30 bus system with and without UPFC. Digital simulation using MATLAB/SIMULINK is done with these models and the results are presented. The effect of UPFC on real power, reactive power and the voltage is also presented.

Improving Power Flow Capacity of Transmission Lines Using DPFC with a PEM Fuel Cell

“…To cater these needs, FACTS devices are playing a very vital role in increasing the efficiency of the transmission system [1][2]. Studies conducted in improving power quality by incorporating FACTS devices can be seen in [3][4][5][6][7][8][9][10][11]. Various algorithms have also been developed with the help of which it is feasible now to efficiently place FACTS devices in the power system, something that has drastically reduced the cost of operation and also has improved the quality of power transfer [12][13].…”
