摘要

针对某300MW机组在降负荷时振动突然增大的原因进行了分析。结果表明

引起该故障的原因为调节阀的喷嘴开启顺序设计不合理。通过实施调节阀开启顺序优化

将原调节阀喷嘴开启顺序由1、4→5→6→2→3调整为1、6→5→4→2→3后

在不停机的状态下处理了振动故障

保证了机组的安全稳定运行。

Abstract

Shafting vibration suddenly increased on a 300 MW unit during the load descending.Unreasonable opening sequence of the control valve was considered as the main reason after analysis.Thus

the original opening sequence 1

4→5→6→2→3 was adjusted and replaced by 1

6→5→4→2→3.The optimization handled the vibration without shutdown

so the safety operation of unit was ensured.
