【摘要】 建立水轮发电机转子三维温度场计算的数学模型,用有限元法对水轮发电机转子1/2轴向长度的三维温度场进行求解,绘出任意一个截面的温度分布曲线。对一台320 MW的水轮发电机进行了数值计算。结果表明,最高温度值与实测值基本相符。
【Abstract】 The mathematical model of 3D temperature field for rotor of hydroelectric generator is derived in this paper. Using the finite element method, the 3D temperature field within the half-axial length of magnetic pole and field winding of a 320 MW generator are obtained. Results show that the temperature of field winding is in accordance with tested value.
