龙滩水轮机转轮的设计和制造评述

龙滩水电站安装9台700MW混流式机组，电站的运行条件十分苛刻：水头变幅大，从97m到179m，最大水头与最小头差值达82m，电站下游洪枯水位差值达40m，电站在系统中担任调频、调峰和事故备用，启动频繁。设计的水轮机转轮，必须具有良好的水头和负荷变化的适应性，稳定运行范围要宽广。龙滩水轮机转轮的设计和制造，在特大型机组中具有代表性，尤其是在工地制作700MW转轮，更居首次。转轮的设计和制造，由伏依特西门子水电设备公司负责，日前此项工作正在进行中，第一台转轮已组装焊接完毕，并进行了退火热处理。文章就龙滩水轮机转轮的水力设计、模型试验、转轮结构设计、转轮工地制造及转轮的最终验收，进行评述并提出一些建议。

Comment on design and manufacture of Longtan hydroturbine runners

The design and manufacture of hydroturbine runners of Longtan Hydropower Station are representative in the super-large hydroelectric generating sets. It is the first time to make 700MW runners in construction site. The design and manufacture of the runners are undertaken by Voith Siemens Hydro Power Generation,Inc.. The site manufacture includes assembly,welding and anneal. This thesis comments on the hydraulic design,the model test,the structure design,the site manufacture and the acceptance inspection of ...
