摘　　要：水电站是实现水能到电能转换的水利枢纽工程,水电站为中国电力体系核心构成,具有拦水发电、防汛抗旱、引水灌溉的作用,还能改善生态环境。谢村源三级水电站发电机设备原通风系统为管道通风的形式,多年运行后产生了较多的问题,如:发电机绝缘性能不断下降,甚至有可能出现导电的现象;发电机效率在长时间管道通风运行后降低等,因此,需要对谢村源三级水电站通风进行合理改造。文章根据谢村源三级水电站基本情况,对三种通风改造方案进行详细分析与比选,最终选择了最优改造方案,并通过实践证明其改造效果很好,为类似工程发电机通风方式改造提供了成功的经验,是值得大力推广的改造方案。The hydropower station is a hydro-junction project to realize the conversion from hydropower to electric energy.The hydropower station is the core component of China’s power system,which has the functions of water interception and power generation,flood control and drought relief,water diversion and irrigation,as well as improving the ecological environment.The original ventilation system of the generator equipment of XiecunyuanⅢHydropower Station is in the form of duct ventilation.After years of operation,it has encountered several problems,such as declining insulation performance of the generators and even the possibility of conductivity.Additionally,the efficiency of the generator decreases after a long time of pipeline ventilation operation.Therefore,the ventilation of Xiecunyuan cascadeⅢhydropower station needs to be reasonably improved.According to the basic situation of Xiecunyuan cascadeⅢhydropower station,this paper analyzes and compares three ventilation transformation schemes in detail.The optimal renovation scheme is selected,and its effectiveness is proven through practical implementation.This successful renovation experience provides valuable insights for similar projects involving generator ventilation renovations and deserves to be widely promoted.
