This thesis aims at enhancing the power quality through an optimal reclosing technique of circuit breakers and power electronics-based controls. A performance comparison among the total kinetic energy based reclosing method, the variable dead time control method, and the total load angle method which is a novel technique proposed in this work, are considered. Simulation results indicate the superiority of the total kinetic energy based reclosing method. The effectiveness of the combined operation of total kinetic energy based optimal reclosing and thyristor controller capacitor is evaluated by considering three indices, namely, voltage index, speed index, and the total harmonic distortion (THD) in case of faults and sudden injection of a large load. Simulation results indicate the effectiveness of the combined operation of the total kinetic energy based reclosing technique and the thyristor-based capacitor. Moreover, the performance of the thyristor-based capacitor is better than that of the thyristor-based resistor or reactor.
