Abstract
Static Var Generator (SVG) is a new generational dynamic reactive power compensation system and the detection of directive current generally uses ip-iq operation mode. However, the command value of output reactive current only depended on the reactive current detection of main circuit based on the ip-iq operation mode in the traditional SVG device. This method limits the real-time compensation and the accuracy of reactive power compensation is not guaranteed based on single detecting point. For solving this problem, an improved method for detecting the reactive current based on instantaneous power balance is proposed in this paper. The current information of detecting point and compensating point are introduced and the compensatory accuracy is improved. The improved method is applied in the Cascaded-SVG and the simulation results with matlab/Simulink verify the correctness and effectiveness of the proposed method.
