独立电源系统中的无刷双馈电机动态运行特性研究

摘要

In consideration that the terminal voltage of the power winding and control winding changes with the change of speed and load,the paper builds the mathematical model of Brushless Doubly-Fed Machine (BDFM)with load based on the d-q model of BDFM in allusion to the character of BDFM in independent power system.Based on the mathematical model,a simulation model is also built in MATLAB/Simulink to research the dynamic response of BDFM to the sudden change of speed and load.%针对独立电源系统中的无刷双馈发电机的特点，考虑到功率绕组和控制绕组的端电压随转速和负载的变化而变化，在无刷双馈电机 d-q轴数学模型的基础上，建立了无刷双馈发电机在带载情况下的数学模型。并基于该数学模型，在 matlab/simulink下建立了转速变化和负载变化的仿真模型，完成了其动态响应特性的研究。
