摘　　要：以简单配电系统为研究对象,采用相量分析法和Matlab/Simulink仿真法,重点分析了系统两种常见的断相故障,研究断相故障对电动机这种特殊动态负荷的影响,并通过仿真结果展示了两种断相故障发生后空载电动机主要电磁量的变化规律,指出了哪种故障更为严重,应该对其重点保护。The phasor analysis method and the Matlab/Simulink technique are used to research a simple power dis- tribution system. Two common open-phase faults of the system are analyzed with some emphasis. Influence on an induction motor caused by the two faults is discussed in this paper. And variation of main electro-magnetic variables of no-load motor is presented by simulation results after each fault takes place. Finally, the more terrible open- phase fault is pointed out and suggested to be protected firstly.
