【Abstract】 In this dynamic reactive power compensation system, industrial computer is employed as the main control tooland a rapid reactive power detecting method with a special thyristor controlling is proposed . It can switch capacitors rapidlywithout any impact, and the fast and real-time compensating characteristics can be obtained with this system on compensat-ing the fundamental wave reactive power in low-voltage networks. The control mode of the main circuit and the schematicblock of the device are also presented detailedly in this paper. The relevant data of the simulated load switching test showsthat the device is effective.更多还原
