Abstract: As a kind of new governing alternator, brushless doubly-fed machines have good prospects for development in the field of wind power generation and water power generation. This paper described the operational principle and analyzed two kinds of mathematical models of BDFM which include three-axis static coordinate 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.
