风电是我国能源构成的重要组成部分。本文选取了应用最广的双馈式风力发电机作为研究对象,通过分析其工作原理建立了双馈式风力发电机的数学模型。利用MATLAB软件对双馈式风力发电机进行建模,对并网前后及转子绕组匝间短路故障状态进行仿真分析,从而证明了所建模型的正确性。
Wind power is an important part of the energy in our country. This paper selected the most widely used DFIG as a research object, and then established the model of DFIG by analyzing the operational principle. After that, MATLAB is used to simulate the DFIG. The changes before and after the synchronization, and rotor winding fault are analyzed to prove that the established model is correct.
