Damping Improvement by Facts Devices: A Comparison Between STATCOM, SSSC and UPFC
N. Senthil Kumar , R. Srinivasan and M. Abdullah Khan
 
Abstract: This study discusses and compares different control techniques for damping undesirable electromechancial oscillations in power systems by using Series /Shunt FACTS controllers. Static Compensators (STATCOM) Static Synchronous Series Compensators and Unified Power Flow Controllers (UPFC). The following disturbances are simulated on a Single Machine Infinite Bus System and the rotor angle/rotor speed deviation response is studied with and without the effect of FACTS controllers: Step change in turbine input and a three-phase fault on the line. The dynamic model of the FACTS controllers has been derived from the circuit theory fundamentals and the simulation results provide useful information on the transient rating of the converter based FACTS controllers. MATLAB/SIMULINK is used for running the dynamic simulations.
