Equivalent modeling method of induction motor contribution to short-circuit current

Energy Reports, 2022
When a short-circuit fault occurs in the power grid, induction motors in the distribution network will contribute to the short-circuit current. Accurate short-circuit current calculation of the motors requires detailed modeling of distribution network ...
