Summary:The existing national standard requires that the contribution of induction motor load to short circuit current be considered, but the lack of induction motor modeling method suitable for power grid simulation calculation in China affects the popularization and application of national standard algorithm. Based on the simulation and calculation of Central China Power Grid, considering the distribution characteristics of medium and low voltage motors on the short-circuit current of high voltage bus, the equivalent method of 110 kV/220 kV bus conversion coefficient of motor contribution short-circuit current in distribution network is put forward.
