摘　　要：在对比分析了有刷和无刷双馈发电机的运行机理的基础上,借助于MATLAB/Simulink仿真软件,分别以功率5 kW、6/2极的磁阻转子的无刷双馈发电机和3.5 kW、4极的有刷双馈感应发电机为例,分析这两种发电机的电磁特性、变速恒频运行特性,并通过实验对两种发电机的变速恒频特性加以验证。仿真和实验结果表明,两种发电机在运行性能上具有相似性。The comparison analysis of operation principle of doubly-fed induction machine and brushless doubly-fed machine was realized in detail.On this basis,the performance of electromagnet and variable speed constant frequency（VSCF） of brushless doubly-fed machines with rated power 5 kW、6/2 poles and doubly-fed induction machine with rated power 3.5 kW、6 poles were analyzed based on Matalb/Simulink.The VSCF performance of these machines was validated by experiment.Simulation and experiment results show that the VSCF performance of brushless doubly-fed machine and doubly-fed induction machine is similar to variable speed constant frequency wind generation.
