摘要：

Due to numerous advantages, in this work, the traditional back-To-back converter is substituted with an indirect matrix converter (IMC) to control the doubly-fed induction generator (DFIG). The recent grid codes require that the wind turbines must have the low voltage ride-Through (LVRT) capability. One of the main challenges of the IMC that slows down the industrial applications is the fault currents handling. In this paper, a new low cost, simple and reliable method is proposed to protect the IMC from large fault currents. This method is based on a novel crowbar structure. The PSIM simulation results confirm the efficiency of the proposed method in satisfying the new LVRT standards. Also, experimental results of a laboratory prototype verify the effectiveness of the proposed method. © 2020 International Journal of Power Electronics. All rights reserved.
