Simulation of Restrike Overvoltage Due to Switching off Shunt Capacitor Bank
摘要
Abstract
Shunt capacitor banks are widely used in power grid for reactive power compensation. However, the operating overvoltage caused by frequent operation of shunt capacitor bank would damage the insulated equipment and decrease the reliability of power system. The operation overvoltage on shunt capacitor bank is mainly referred to the restrike in switching-off action, while switching-on action usually does not generate the overvoltage which harms capacitor's insulation. In this paper, a model is designed by adding a normal closed breaker for simulating the overvoltage due to switching off shunt capacitor bank by a vacuum circuit breaker, and the restrike overvoltage is calculated with the model. Moreover, the effect of limiting restrike overvoltage on shunt capacitor bank by using an MOA arrester is simulated. Simulation results show the proposed method is feasible.关键词
