Abstract: Aiming at the problem that the short-circuit current calculation standards and methods are not unified,an accurate equivalent model modeling method suitable for short-circuit current calculation is proposed. The equivalent induction motor load model of distribution network is established,the induction motor parameters and load proportion are determined,and the short-circuit current calculation results with small deviation from the real value can be obtained. Based on the calculation example of Heilongjiang actual power grid,the typical load station is modeled,the short-circuit current is calculated by using the determined load proportion of substation equivalent induction motor,and compared with the calculation results of Heilongjiang dispatching algorithm and planning algorithm,so as to provide reference opinions for the determination of short-circuit current calculation standard.
