An accurate identification of the electromagnetic parameters of synchronous electric machine is the precondition for analyzing power system running and controlling system design.It is a tradi-tional way to identify the parameters of sudden three-phase short circuit with least-square and Kalman filtering.Influenced by the maneuverability of the synchronous machine sudden three-phase short circuit and the nonlinear of the machine parameter model,the machine parameters are difficult to mea-sure.By combining the new method of improved wave transform and artificial neuron network with the synchronous machine sudden line-to-line short circuit test in identifying the parameters,the transient parameters of three phase synchronous machine were identified.The identifying precision of the parameters was improved.The simulation test proves that the method is effective.
