摘要
为解决张河湾抽水蓄能水泵水轮机工况低水头空转运行时,机组振动较大的问题,法国ALSTOM公司对导水机构进行了技术改造,加装了2个非同步装置(MGV装置)。文章主要介绍了MGV装置的工作原理、安装调试及增加非同步导叶所取得的效果。
In order to solve problem of large vibration of unit of Zhanghewan pumped storage hydropower station pump-turbine operating under low water head,the distributor has been reconstructed by ALSTOM Corporation,and two nonsynchronous devices have been installed.The paper mainly introduces working principle,installation and debugging of nonsynchronous devices（MGV device）,and the effect of increasing nonsynchronous guide vane.
