黄丹水电站水轮机增容防蚀技术改造的可行性研究

摘要

By taking the Kaplan units of Huangdan Hydropower Station as an example, the study on the feasibility of increase in capacity and corrosion prevention for the runner with good hydraulic performance is conducted. This paper analyzes the issues, such as flow difference, epispastic height, water thrust and fly speed and so on before and after the technological transformation. In this way,the technological transformation of Huangdan Hydropower Station is realized, and the economic benefit of this station is improved.%通过采用水力性能优良的转轮增容防蚀技术,对黄丹水电站轴流转桨式机改造的进行了可行性研究.文章对改造前后有关流道的差异、吸出高度、水推力和飞逸转速等问题作了分析.通过可行性研究,以期对黄丹水电站进行技术改造,提高其水电站的经济效益.
