Abstract

In order to study fluid state influence on stator temperature of generator, this paper applies heat transfer theory and hydromechanics to analyze water cooling system. The water velocity was studied when the water cooling winding was blocked in turbo-generators and the stator 3D temperature field was calculated by the thermal network method. The result showed different water velocity could be lead to different temperature. The authors put forward block coefficient and analyze it to be feasible in the stator temperature calculation basing on cooling winding blocked in different degree. The research provided the theories basis for the design and on-line monitor in large generator stator cooling system.
