无刷双馈电机工作原理和数学模型的研究

摘要

As a kind of new governing alternator, brushless doubly-fed machines have good prospects for de-velopment in the field of wind power generation and water power generation. This paper described the opera-tional principle and analyzed two kinds of mathematical models of BDFM which include three-axis static coor-dinate mathematical model and d-q coordinate mathematical model. Based on d-q coordinate mathematical model, dynamic simulation model in Matlab/Simulink of BDFM was set up. The mathematical model was proved to be correct through a series of simulation. It provided the foundation for future research on BDFM.%无刷双馈电机作为一种新型的交流调速电机,在风力发电和水力发电中都有很好的发展前景.本文介绍了该电机的工作原理,分析了该电机的两种数学模型-三相静止坐标系中的数学模型和d-q坐标系中的数学模型,并在d-q坐标系数学模型基础上搭建BDFM的Matlab/Simulink动态仿真模型,通过一系列的仿真验证了数学模型的正确性,为以后对该种电机进行深入的研究奠定了基础.
