Abstract:

通过对3 MW感应发电机的部分结构进行简化，建立了发电机定子和转子的三维温度场和流体场的流固耦合模型，并根据流体力学基本理论，采用有限体积法在Fluent仿真软件平台上对电机的温度场及流体场进行了仿真计算。所提出的仿真计算方法不仅为电机温度场的研究和分析提供一定的参考作用，也为电机结构优化和通风设计提供了理论依据。
By simplifying the structure of the 3 MW induction generator, the fluid-solid coupled model of 3D temperature field and fluid field for stator and rotor is built; the numerical simulation of temperature field and fluid field distribution for stator and rotor is done by using the finite volume method on Fluent simulation software platform based on hydromechanics theory. The proposed method can not only provide certain reference for studying temperature field of the generator, but also provide a theory gist for structure optimization and ventilation design of the generator.
