| 摘 要： | 提出了一种新的建模方法,即在电励磁双凸极电机电磁场有限元计算的基础上,利用M atlab对电励磁双凸极无刷直流发电机进行非线性建模与仿真;并导出了电励磁双凸极电机无刷直流发电系统考虑换相过程时的非线性仿真模型。最后,用提出的非线性建模和仿真计算方法,对一台三相12/8极电励磁双凸极无刷直流发电机的空载电势波形进行了仿真,进而计算出电机的空载电势。结果表明:空载电势和空载特性的仿真与实验结果一致性较好。

| Abstract: | A new nonlinear modeling method is presented based on the FEM analysis.By using the Matlab simulation tool the field-winding doubly salient brushless DC generator is nonlinearly modeled and simulated.The nonlinear simulation model of the system is derived when the current commutation process is considered.Finally,using the proposed modeling method,a 12/8-pole field-winding doubly salient generator is simulated and the winding induced voltage under no-load condition is given.Also,the no-load output characteristics are concluded.Simulation results are consistent with experimental(data.) |
