Simulation Analysis of Air Cooling System Flow Field Characteristics for Generator-Motor in Pumped Storage Power Stations

At present, the heating power of the generator-motor of the pumped storage power station is continuously improved, and the optimization of the air path is the main way to improve the air cooling performance. In this paper, a certain type of generator-motor is taken as the research object. The CFD software is used to simulate and analyze the air flow characteristics inside the motor, which provides a reference for the optimization design of the air path and the improvement of the cooling performance.
