Circuit model of synchronous machine and the quantitative process during short - circuit period are deduced . many parameters of synchronous machine except for transient time constant can be identified in a short time with the elaborately designed algorithm 文中给出了同步机电路模型，定量分析了三相突然短路的过渡过程，所研制的计算机算法可在较短的时间内辨识出除暂态时间常数外的同步机的诸多参数。
