Abstract
According to the reactive characteristics of the distributed generation and the shortcomings of the compensation system for static var compensator(SVC),based on the instantanous reactive theory and symmetrical component method,a real-time method for calculating the value of reactive power of the system is presented.In response to the reactive power value,the compensation current which is used for operations of SVC can be obtained through PI regulator.Simulation results by the matlab/simulink tools show that the proposed method is feasible and can speed up the response of compensation device greatly.
