摘要
In this paper, the mathematic model of 3D magnetic field in the rotor end region of a large, turbogenerator at asynchronous operation is presented. The general process of different boundary conditions and 3D adaptive-mesh generation are used for increasing computation speed and reducing memory. Taking 300MW turbogenerator as an example, the rotor end field and eddy current density are calculated. The results can be used for analyzing the performance of the generator.
