Abstract :
In order to explore the effect of changes in altitude and operation condition on the heat transfer performance, in this paper, a 1.5MW doubly-fed wind generator was taken as an example. The three-dimensional fluid flow and heat transfer coupling calculation model was established. Considering the actual operation environment and working condition, temperature field was calculated by using finite volume method. The relationship of the heat transfer performance of the generator and the related influencing factors can be confirmed by the analysis of the rheological properties and heat transfer performance, which laid a theoretical foundation for operational monitoring and failure prediction of wind generator in harsh environment.
