摘要
黑麋峰抽水蓄能电站为了解决原机组在过渡过程及部分运行工况下厂房局部振动比较强烈的问题,对机组进行了改造,在世界范围内首次采用了6+6长短叶片型式的转轮。本文建立厂房结构的三维有限元模型,对机组改造后的厂房振动特性进行研究,对比分析机组改造前后的厂房振动响应,表明相同出力工况下,转轮改造后厂房结构总体振动响应较转轮改造前降幅超过50%,说明应用6+6长短叶片型式转轮的机组能够有效降低厂房振动影响。
In order to resolve strong local vibration problems of power plant in some working conditions and transient process of original unit in Heimifeng pumped storage power station,the unit is renovated.6+6 long-short typed blades are used in the first time in the world.Research on vibration characters of power plant after the unit is renovated is made by establishing three-dimensional finite element model of power plant structure,and vibration response of power plant as analyzed and contrasted.It indicates that under the same output condition the vibration response amplitude of power plant structure decreased by more than 50%after the runner renovation.It shows that the vibration influence of power plant can be effectively decreased by applying 6+6 long-short blades typed runner.
