• Combination of optimal reclosing of circuit breakers and SVC is proposed for power system transient stability enhancement.
• The performance of the proposed combination of optimal reclosing and SVC is compared with the combination of conventional reclosing and SVC.
• The performance of the proposed combination of optimal reclosing and SVC is better than that of the combination of conventional reclosing and SVC.
• Combined operation of optimal reclosing and SVC can be considered as an effective means for power system transient stability enhancement.
This paper proposes the coordinated operation of optimal reclosing of circuit breakers and Static Var Compensator (SVC) for enhancing the transient stability of a multi-machine power system. The transient stability performance of the combined operation of optimal reclosing of circuit breakers and SVC is compared with that of the combined operation of conventional reclosing of circuit breakers and SVC. The total kinetic energy (TKE) of the generators in the system is used to determine the transient stability enhancement index. Simulations are performed through Matlab/Simulink software. Simulation results for both the three-line-to-ground (3LG) and single-line-to-ground (1LG) permanent faults at different points of the power system indicate that the proposed combination of optimal reclosing of circuit breakers and SVC can enhance the transient stability of the system well. Also, the performance of the proposed method is better than that of the combined operation of conventional reclosing of circuit breakers and SVC.
