摘　　要：阐述了交流电机的多回路分析法 ,奠定了发电机内部短路保护计算的理论基础。多台各种类型同步发电机内部故障的仿真及其与试验的对比证明了多回路数学模型和方法的正确。多回路分析法已成功应用于国内 10多个电站发电机定子绕组内部故障计算和保护方案设计。以多回路法为理论基础开发的发电机故障分析软件也已面世。The multi loop analysis method for ac machine is represented. The check of protection sensitivity and the design of main protection scheme for generators are based on the multi loop method. The digital simulation results and the experimental results of different types of synchronous generators have verified the multi loop mathematical model and the simulation program. The multi loop method has been successfully applied to the simulation of stator winding internal faults and the design of main protection schemes of more than ten power stations. Based on the multi loop method, the internal fault analysis software has been developed.
