| Abstract: | In this paper, the three dimensional temperature field of the hottestregion in the stator of hydroelectric generator under load is calculatedby means of finite element method. The mathematical model and func-tion of stationary temperature field are derived at first, then the dis-cretizations are carried out using the triangular prism element. Theprogram of 3D automatic mesh generation and F. E solution are presen-ted. Finally, the 3D temperature fields of the hottest region of two largewater-wheel-generator are calculated and compared with measured valuesand the values obtained by other methods. Results show that the methodand computer program are correct. |
