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 文中給出了同步機(jī)電路模型,定量分析了三相突然短路的過(guò)渡過(guò)程,所研制的計(jì)算機(jī)算法可在較短的時(shí)間內(nèi)辨識(shí)出除暫態(tài)時(shí)間常數(shù)外的同步機(jī)的諸多參數(shù)。
