摘要：

Finite-element method is applied to calculate the stable stator three-dimensional (3D) temperature field of a hydro-generator SF125-96/15600. First, 3D controlling equation of heat conduction and its equivalent functional equation are presented. Secondly, all the parameters for simulation such as heat conductivity coefficients of iron core and stator coils, heat convection coefficients of each surface, are calculated. Thirdly, iron and copper losses are deduced by electromagnetic analysis. Then, the stator temperature field with and without skin effect are calculated. Comparing the two kinds of simulation results with that of measured, it is verified that the simulation is effective, and that the temperature field of slot under skin effect is more uneven than that of without the effect. So, more accurate temperature distribution of the key component of hydro-generator can be got on which online stator thermal monitoring and optimum design can be carried out.
