中文摘要: 本文主要描述联合循环机组运行状态的改变，机组由调峰运行到长期连续运行，因现场管道布置不 合理，导致低压主蒸汽温度突降，引起汽轮机发生轻微水冲击的事件。文章分析了事件产生的原因，结合实 际情况进行技术改造，给同类机型在设计初期合理进行管道安装布置提供一定的借鉴意义。
Abstract:This article mainly describes the changes in the operating status of the gas-steam combined cycle unit. The unit goes from
peak shaving operation to long-term continuous operation，and due to unreasonable on-site pipeline layout，the temperature of tlie low-
pressure main steam suddenly drops，causing a slight water shock event on the steam turbine. The article analyzes the causes of the
incident and makes technical improvements based on the actual situation， providing certain reference significance for the reasonable
pipeline installation and layout design of similar models in the early design stage.
