Performance analysis of IEEE 9 Bus system using TCSC

The events of damaging blackouts, voltage fluctuation and collapses are a point of major concern for electricity boards, power system engineers and the consumers all over the globe. Better compensation of reactive power in a system will lead to a better voltage profile, improving the overall power quality. In this paper authors are focusing on reactive power compensation of a IEEE-9 Bus system using thyristor controlled series capacitor. The simulation and the analysis of data is carried out using Mipower (version9.0) software. Netwon Raphson method of load flow solutions has been used. At first we have analyzed the IEEE-9 bus system under the standard test data and after that we analyzed the same IEEE-9 bus system with Thyristor controlled series capacitor. The system is studied to analyze reactive power compensation, voltage profile and line losses with and without TCSC. The results obtained in both the cases have been comparatively analyzed and proves that TCSC improves the performance of the system.
