摘要：新型级联式无刷双馈发电机可以看作是普通级联式双馈电机的一种特例，主要用于风力发电，当电机转速变化时，不需要改变输入励磁电压的频率就可以保证电机输出的电压频率恒定，方便的实现了变速恒频发电。对新型级联式双馈电机的工作原理进行了简要论述，在Ansoft软件里面建立了电机的模型，并导入到Simplorer软件，把两个电机级联起来进行了仿真。仿真结果表明新型级联式双馈电机只需确保两电机转子同轴同相序连接，且两电机极对数相等，即可实现无需变频器的变速恒频发电。关键词：内置式“一”型；重复单元；齿槽转矩；级联式无刷双馈电机；变速恒频；仿真Abstract: The new cascade Brushless Doublyfed Machine (BDFM) is mainly used for wind power, when the speed of prime mover changes, without changing the input frequency of the excitation current, this generator can guarantee the frequency of the output current is constant,which realize the variable speed constant frequency (VSCF) power. The working principle of the new cascade BDFM was derived, and two motors were established in Ansoft software, then imported into Simplorer software,cascaded and simulated. Simulation results show that if the new cascade BDFM make sure two coaxial rotorsare connected with the same phase sequence and two motor pole pairs are equal, it can achieve VSCF power without inv erter.
