摘　　要：本文提出了一种分析计算同步电机异步运行特性的新方法——场路结合分析法;同时还提出了计算电机内非线性涡流电磁场的高阶混合有限元法,建立了更为准确的同步电机数学模型,改进了分析计算同步电机异步运行过程的传统瞬变分析法。对同步电机异步起动的分析计算表明,由本文方法所得的结果比由传统方法所得的结果更为按近实测值。In this paper, a new method is developed——field-circuit combined analysis method, for analysing and calculating asynchronous operation of synchronous maehines. At the same time, a high-order mixed finite element method for calculating nonlinear eddy current electromagnetic fields is presented; a more accurate model of synchronous machines is set up; and traditional transient analysis methods for calculating asynchronous operation of synchronous maehines are improved. The calculation of starting performances of synchronous motors shows that the results of this paper are nearer the measurements than those of the traditional method.
