【 摘 要 】

In this paper, a new method of optimal reclosing based on the load angles of the synchronous generators in a multi-machine power system. First the optimal reclosing times are determined, and then the performance of the reclosing technique is compared. In order to analyze the reclosing techniques, the IEEE nine bus power system model is considered. Both balanced and unbalanced temporary and permanent faults at different locations in the power system model are considered. Two indices are considered to evaluate the system performance in terms of power quality enhancement. And the Indices are speed and voltage. Simulation results indicate that the proposed total load angles based optimal reclosing technique using STATCOM is effective to maintain the power quality in a multi-machine power system. Moreover, the performance of the proposed reclosing method is better than that of the conventional reclosing method. Index Terms—Optimal Reclosing, Power Quality, STATCOM, successful Reclosing, Total Load Angles, unsuccessful Reclosing.
