| Abstract: | The three-phase short circuit currents of bulk electric power system are very high,and the high currents do harm to the working of the system.What's more, the anlysis of the short-circuit currents is very complex.In this paper,several analytical methods of three-phase short circuit of infinite bulk electric power system are presented: integro-differential equation ,three-factor method ,lapace transformation,state variable,computer simulastion analyze.The three -factor method is convenient and rapid to analyze this system. |
