摘要
本文首先从电机基本原理出发,分析了双馈电机的等效电路以及在同步坐标和d-q坐标系下电机的数学模型,其次阐述了矢量控制原理和基于定子磁链定向的矢量控制策略,最后利用MATLAB 7.6仿真软件搭建了基于双馈感应发电机的变速恒频风力发电系统,并对仿真结果进行了分析研究。
Firstly, this paper starts from the basic principles of motor, analyzes the equiva- lent circuit and mathematical model of the DFIG in synchronous coordinate and d-q coordinate; secondly, it elaborates the vector control theory and the vector control strategy based on the stator flux orientation; finally, it sets up the VSCF wind power generation system based on doubly fed induction generator using the MATLAB 7.6 software, and the simulation results were analyzed.
