In this paper, the impact of multiple shunt and series compensators on transient stability of a power system is investigated. Modeling and analysis of a real based multi machine-22 bus system with Static Var Compensator (SVC) and Thyristor Controller Series compensator (TCSC) are performed. The location of the compensators is determined based on the weak buses and transmission lines with the highest voltage drop in the system. Transient stability effects are analyzed for three system cases, one without compensators, one with one compensator at a time and the last one with multiple compensators. Angle and angular speed of rotors, voltage variations at each bus are observed. The simulation results showed that the system with multiple compensators can damp oscillations more effectively.
