半直驱永磁风力发电机冷却介质温度场分析研究

摘要

发电机温升是发电机性能的一个重要指标.为验证大功率半直驱永磁风力发电机冷却系统设计的合理性,使用有限元法对发电机冷却介质温度场进行仿真计算,并与设计值进行对比和分析.所做研究可为发电机冷却系统的优化提供参考.%Temperature rise of the generator is an important indicator of generator performance.In order to verify the rationality of the designed cooling system in high-power semi-direct drive permanent magnet wind power generator,finite element method was used to simulate and calculate the temperature field of the cooling medium in the generator and the results were compared and analyzed with the design value.The study can provide a reference for the optimization of the cooling system in the generator.
