(2) at speed points where the double-cage effect is significant from the measured stator instantaneous power. Three motors were tested in the laboratory and the proposed method was applied to obtain their parameters. The steady-state torque-and current-slip curves predicted by the estimated parameters are compared with those measured in the laboratory to check the accuracy of the method.
Abstract-A new method for determination of the steadystate equivalent circuit parameters of wound rotor induction motors using experimental starting transient measurements is presented. The algorithm data are the stator currents and voltages and mechanical speed. The algorithm uses the least-square method and motor dynamic equations in the synchronous reference frame. Moreover, an approximation of the rotor flux that improves the accuracy of the estimation method, as well as a detailed study of errors, is included. The estimation method is applied to starting transient measurement data of a 2kW wound rotor induction motor, and parameter accuracy is verified by comparing steady-state torque-and current-slip curves calculated with the estimated and laboratory measured parameters.Index Terms-Equivalent circuits, wound rotor induction motor, starting transients.ARAMETER determination of induction motors is an important topic because these machines are one of the most common loads in the grid. Estimation accuracy is crucial because of the importance of parameters in power system dynamic behavior during faults and other perturbations. Another important area is high performance ac drives, where parameter estimation is key in controller tuning. Several approaches to induction motor parameter estimation have been presented. IEEE The main issue in this paper is to develop an estimation method. One major drawback of many parameter estimation procedures is the need for large currents in the locked-rotor
