| Abstract: | The V-curve of round-rotor synchronous machine is derived based on the analysis of its linear model and its magnetization curve is obtained by the polynomial fitting based on the no-load test data.The method to exactly analyze its V-curve is proposed,i.e.the excitation reactance parameters vary with the main flux saturation degree based on steady-state linear model.The magnetization parameter is estimated by the least-squares parameter identification with the consideration of main flux saturation and the ex... |
