Another method of simulation on the rotor side control system of DFIG and its performance to disturbance

This paper proposed a method of building the rotor side power control system of DFIG. In the past works, the current control loops were turned to PI controllers and the trouble is to set the proper integral and proportional gains. By deducing the rotor side exciting voltage equations and using the S-functions, the simpler method of modeling were proposed in the paper. The performance comparisons with the well-established models and some typical simulations based on the new model were made. The results validate the rightness of the presented method.
