Abstract: Whether the inverter can match the doubly fed induction generator(DFIG) well will depend on the accuracy of the equivalent circuit parameters of the generator, which will also affect the performance of the entire system. Based on the equivalent circuit of the generator, and the circuit equations under the three conditions of idling, locked roter and opened rotor, The separation method for equivalent circuit parameter is proposed. The sample motor test data show that the calculation method is proved to be accurate.
