就水轮发电机组而言,振动现象势必会降低电站的发电效率和经济效益,并严重影响整个机组的正常运行。对此,本文以中小型水轮发电机组作为研究对象,分析了引起机组振动的三大原因,并简要概述了龙首一级水电站机组振动故障的处理方法。 As far as hydro-generator units are concerned, the vibration phenomenon will inevitably reduce the power generation efficiency and economic benefits of the power station and seriously affect the normal operation of the entire unit. In this paper, the small and medium-sized hydro-generator set as the research object, analyzes the three causes of the unit vibration, and briefly summarizes the unit of Longsheng first hydropower station vibration fault handling.
