摘要
为了在电磁暂态仿真软件PSCAD中对三相永磁推进电机进行仿真分析,针对PSCAD自带模型不含转子运动方程的不足,采用隐式梯形法在PSCAD中建立三相永磁同步推进电机的仿真模型,通过与自带模型对比仿真,验证所建模型的正确性,在此基础上对采用脉宽调制变频调速的永磁推进系统动态调速过程进行了仿真分析,为永磁推进深入研究及后续多相永磁电机建模奠定了基础。
For simulation of 3-phase permanent magnet synchronous machine(PMSM) for propulsion in the electro-magnetic transients simulation software of PSCAD, with the fact that the motion equation of rotor is excluded in the PMSM model contained in PSCAD's library. The implicit trapezoidal method is applied and the entire model of PMSM is programmed and built in PSCAD. A comparison simulation is carried out between the PMSM model built and contained in PSCAD to validate its correctness, then the dynamics of the PMSM using pulse width modulation is simulated and analyzed, which lays the foundation for the modeling of multiphase PMSM and further research of permanent magnet propulsion.
