摘要
阐述燃气蒸汽联合循环热电联产机组的特点,汽轮机轴位移受供热抽气流量或压力波动影响大,甚至会触发轴位移保护动作跳闸问题,探讨汽轮机抽气系统的可靠性优化策略,实现的效果评价。
This paper describes the characteristics of gas steam combined cycle cogeneration units.The displacement of the steam turbine shaft is greatly affected by fluctuations in heating extraction flow or pressure,and even triggers the tripping of the shaft displacement protection action.It explores the reliability optimization strategy of the steam turbine extraction system and evaluates the effectiveness achieved.
