Design, Testing, and Analysis of STATCOM and TCSC for Real-Time Simulation

FACTS controllers are found to be effective in improving transient stability of power system. WSCC 9-bus system has been utilized as test system developed in MATLAB/Simulink software. This paper investigates the improvement of transient stability of a 3-machine 9-bus WSCC system using STATCOM and TCSC and their relative performances are studied with the help of simulation results validated with OPAL-RT real time simulator. Particular attention is paid to real-time simulation approach which provides adequate and comprehensive modeling of electric power systems (EPS) containing FACTS. Simulation results are quite encouraging and show the effectiveness of STATCOM and TCSC in improving transient stability of the test system.
