The overview of identification methods for equivalent circuit parameters of the induction motor at standstill was presented in the paper. The modified current-step-response identification method was described in detail and its practical realisation was presented. The obtained results were evaluated and the current-step-response of the motor at standstill as well as motor transients during line-start operation obtained by numerical simulation were compared with experimental tests. The evaluation of the convergence of two numerical algorithms used in the identification process was performed and the time dedicated to numerical calculations was compared from the point of view of the real-time systems application.
