Transient Stability Improvement using Shunt and Series Compensators

Background/Objectives: To study the improvement of transient stability using FACTS devices (TCSC and STATCOM). Methods/Statistical Analysis: The objectives are met by varying the value of capacitance value of constant capacitor by fluctuating the firing angle of TCR. STATCOM is realized by linking the system with voltage source via transformer. Findings: In the transmission line of 8 bus system FACTS device is used and both ends power transfer is controlled. Major transient parameter are stimulated individually and analysed. Applications/Improvements: The single phase and three phase systems are modeled with and without FACTS device and the results are simulated using MATLAB.
