【摘要】 建立水轮发电机定子三维温度场计算的数学模型和泛函，用有限元法对水轮发电机定子 １／２轴向长度的三维温度场进行求解，得到任意一个截面及沿轴向方向的温度分布曲线。对一台 ３２０ ＭＷ的水轮发电机进行计算，结果表明，定子最高温度值与实测值基本相符。更多还原

【Abstract】 The mathematical model and functional of 3D temperature field of hydroelectric generator stator are derived. Using the finite element method, the 3D temperature field for half-axial length of stator are solved. Finally, the axial temperature distribution for arbitrary section of a 320MW generator is obtained, which is in accordance with testing values.更多还原
