摘　　要：在使用电容的单相电源供电系统的电路中,异步电机的运行是众所周知的。异步电机在单相电源供电系统中的详细研究已有文献记载[1],但是在永磁同步电动机中却较少进行这样的研究。为提高电能的利用率,解决电力不足而导致电能消耗急剧上升时,电能的高效利用率问题,对单相电源供电系统下的永磁同步电动机的稳态运行性能进行了详细研究。利用对称分量理论结合坐标变换理论进行分析,推导出在单相电源供电系统下,永磁电动机运行时所需电容值大小的几种计算方法,并对其进行比较,通过Matlab进行仿真实验。结果表明:利用最小不平衡因数和最大效率法所求得电容值为最佳电容值,可使永磁同步电机达到良好的运行性能,有效的提高了电机的效率。The operation performance of three-phase induction motor from a single phase supply system with a capacitor is well known. The detailed research of induction motor in this supply system had been recorded in the literature [ 1 ]. While, three-phase PMSM under such supply has not yet caused too much attention. To improve the utilization of energy and solve the power shortage, this paper pres- ents an analysis research of steady state performance to PMSM from a single-phase supply. By using symmetrical component theory com- bining with coordinate transformation theory, it deduce several calculation methods of capacitance in this single-phase supply. Through the comparison of several calculation methods of capacitance, it can achieve best steady state performance by satisfying the minimum un- balance factor and maximum efficiency to calculate capacitance by simulation experiment in Matlab.
