This work proposed the coordinated operation of the bridge type fault current limiter (BFCL) and optimal reclosing of circuit breakers to enhance the transient stability of a multi-machine power system. The transient stability performance of the proposed method was compared with that of the thyristor controlled series capacitor (TCSC) and the dc resistive fault current limiter (RFCL) considering the same optimal reclosing technique. The total kinetic energy (TKE) of the generators in the system was used to determine the transient stability enhancement index. Also, the critical clearing time was presented as a stability limit. Simulations were performed by using the Matlab/Simulink software. Simulation results for both permanent and temporary faults at different points in the IEEE 30 bus power system and single-machine power system indicated that the coordinated operation of the BFCL and optimal reclosing of circuit breakers can enhance the transient stability of the system well. Also, the performance of the proposed method was better than that of the TCSC and RFCL considering the optimal reclosing technique.
That work was published in Electric Power Systems Research.
