Motor Parameter Estimation Analysis

The ETAP Motor Parameter Estimation program calculates equivalent circuit model parameters for motor at starting condition. The calculation is based on advanced mathematical estimation and curve fitting techniques, which require only the machine performance characteristic data. The estimated model, together with its parameters, can be used to represent the motor dynamics during motor starting and transient stability studies. Machine characteristic curves based on the estimated model are automatically updated into the corresponding motor editor. Additional key machine characteristic and nameplate data are automatically calculated based upon the estimated model.
