Squirrel-cage inductiom machines are widely used as motors because of their robustness and cost effectiveness. They are also utilized as wind generators because of capability of asynchronus operation with power grid. However, the induction machines have the disadvantageous point that the transient current amounts to several times as large as rated value when they are injected to the power system, and causes the voltage variation of the power system. Hence, the authors investigated the evaluation method of machine transient current through simulation. We derived the nonlinear state equations to denote machine dynamics by means of d-q axis notation. Then we simulated the machine transient currents, changing the phase angle of source voltage. A special dedicated simulation language developed by one of the authors was used for simulation. The simulation results agreed well with the experimental results.
