| Abstract: | The paper introduced the ground principle of work and present voltage sag detection methods of dynamic voltage restorer. On this basis this paper proposed a sort detection method based on the least-squares method. It can separate from the fundamental wave positive-sequence and get the required voltage compensation to link the compensatinon strategy when the network voltage appeared the three phase unbalance voltage sag, the real-time character qutie better. |
