摘要
无刷双馈电机已在风电等行业得到广泛应用,分析其瞬态性能十分必要。为了分析笼型转子无刷双馈电机在单馈异步运行、双馈同步运行、双馈亚同步运行和双馈超同步运行四种运行模式下的瞬态特性,建立无刷双馈电机在转子d-q旋转坐标系下的瞬态数学模型;用Matlab构建系统仿真模型,通过实例对无刷双馈电机在单馈异步运行、同步运行、双馈亚同步运行和双馈超同步运行四种运行模式的瞬态性能进行仿真分析。通过实例对无刷双馈电机单馈运行和双馈运行进行了仿真,仿真结果与理论分析一致。
Build brushless doubly-fed motor rotor in the d - q rotating coordinate system under transient mathematical model; Matlab system simulation model was constructed, an example of brushless doubly-fed motor run in a single feed asynchronous, synchronous operation, doubly-fed synchronous operation and doubly-fed synchronous running the transient performance of the four kinds of operating mode simulation analysis, the simulation results are in conformity with theoretical analysis.
