Abstract:
 Abstract:In order to solve the problem that the preprocessing of building the fieldcircuit coupled model for analyzing the internal faults of synchronous generators is timeconsuming, a parametric modeling method for the fieldcircuit coupled model is given in this paper This method applies to establish the fieldcircuit coupled model of synchronous machines with different dimensions, salient and nonsalient and different winding types Moreover, a 1400MW turbogenerator is taken as an example, and the fieldcircuit coupled model is built using the parametric modeling method, then the transient process of this generator during the internal faults is simulated It shows that the air gap magnetic field located in the internal fault area is serious distortion, and a strong evenorder harmonics appear The magnitude of the fault currents are very large, which may result in terrible damages to the machine the damper bar current peaked periodically, and the period equals the time of one rotation of the rotor
