# 300 MW汽轮发电机电磁性能的有限元仿真计算Finite Element Simulation of Electromagnetic Properties for 300 MW Turbogenerator

Abstract: In this paper, no-load characteristic, short-circuit characteristic and air-gap flux density, EMF, electromagnetic torque and core losses of a 300 MW turbogenerator are calculated and presented by using the Ansoft Maxwell finite element software. The coreloss distributions in stator yoke along radial are simulated by using the accurate Bertotti model. All the results can provide theoretical foundation for temperature field calculation and reducing consumption measures, and at the same time provide some references for the further study of unit operation and parallel operation as well as various fault diagnosis of the turbogenerator.
