【摘要】 随着无刷双馈电机(BDFM)理论的日趋成熟,该类电机在风力发电等工业应用场合越来越体现出广泛的前景。分析了无刷双馈电机工作原理以及无刷双馈变速恒频发电系统的实现。依据BDFM在d-q坐标系的动态数学模型,提出变速恒频运行条件下独立发电的标量控制策略。最后搭建Matlab/Simulink模型进行仿真验证了该策略的可行性,并提出了一些提高系统动态响应的方法。更多还原

【Abstract】 With the maturing of the brushless doubly-fed machine(BDFM)theory,this kind of motor is showing its great expectations in wind power and other industrial applications.This paper analyzes the working principle of the brushless doubly-fed motor and the realization of Variable speed constant frequency(VSCF)double fed wind power generation.The paper puts forward the scalar control strategy of VSCF on the basis of dynamic mathematical model of the BDFM in d-q coordinate system.And finally the author builds the Matlab/Simulink model to simulate and verify the feasibility of this strategy,and puts forward some methods to improve the system dynamic response.更多还原
