水电站冲击式水轮机调速器技术发展历程及研究

Development History of Impulse Water Turbine Governor of Hydropower Stations in China

随着高水头水电站的大力开发和应用,冲击式水轮机不断向着大容量多喷嘴方向发展,适应冲击式水轮机组控制特性的专用调速器应运而生,且技术发展迅速。通过我国第1座高水头电站———云南以礼河水电厂在不同时期具有代表性的冲击式水轮机调速器的运行实践,回顾和总结近半个世纪以来冲击式水轮机调速器技术的发展历程,汇报作者多年来对冲击式水轮机调速器研究的体会和认识,希望对冲击式水轮机调速器的规范、选型和应用有所帮助。

With the development and application of high water-head hydropower stations, big capacity and multi-nozzles became the development tendency of impulse water turbine. Specialized governor which adapts to the char-acteristics of impulse water turbine emerged and developed rapidly. The authors reviewed and summarized the de-velopment history of impulse water turbine governor technology in the past half a century according to the operation practices of typical governors used by Yunnan Yilihe River Hydropower Station, the first hydropower station with high waterhead in China. By offering the experiences and knowledge, it is expected to be helpful for the standardi- zation, lectotype and application of impulse water turbine governor.
