Abstract

This thesis proposes the coordinated operation of optimal reclosing of circuit breakers and superconducting fault current limiter (SFCL) for enhancing the transient stability of a multi-machine power system. Transient stability performance of the combined operation of optimal reclosing of circuit breakers and SFCL is compared with that of the combined operation of conventional reclosing of circuit breakers and SFCL. Moreover, to see the effectiveness of SFCL in improving the transient stability, its performance is compared with the static var compensator (SVC). Simulation results in Matlab/Simulink environment for permanent balanced and unbalanced faults at different points in the system indicate that the proposed combination of optimal reclosing of circuit breakers and SFCL/SVC can enhance the transient stability of the system well than the combined operation of conventional reclosing of circuit breakers and SFCL/SVC. Furthermore, the SFCL performs better than the SVC for the same operating conditions of the system.
