摘要:
 为了研究汽轮发电机转子温度分布情况,以某型空冷汽轮发电机转子为研究对象,建
立三维物理模型。依据CFD 原理,利用合理的基本假设和边界条件,对转子内冷却介质和固体部
件的温度场进行数值求解,分析转子的温度分布。计算结果表明转子线圈温度最高达到了102℃,
位于转子直线段的端部,没有超过温度限制; 转子线圈整体平均温度为88. 0℃,厂方试验值为
87. 5℃,误差为0. 57%,所得结果为汽轮发电机的安全运行提供保障。
Abstract:
 In order to study the temperature distribution of the turbo-generator rotor,an air-cooling turbogenerator
rotor is aimed as the research object,and a three-dimensional model of the rotor is established. According
to the principle of CFD,basic assumptions and boundary conditions are selected,temperature field of cooling
medium and solid part in rotor is solved numerically,and the temperature field distribution law of rotor is analyzed.
The calculation results show that the highest temperature of the rotor winding temperature reached 102℃ which is at
the end of the rotor line segment,and does not exceed the temperature limit. The wholer rotor winding draw
temperature is 88. 0℃ and the manufacturer test value is 87. 5℃,the error is 0. 57% compared with the generator
for test data provided by the manufacturer,which guarantees the safe operation of turbo-generator.
