摘　　要：汽轮机调速系统是通过调整进入汽轮机的蒸汽流量,使汽轮机输出功率和负载功率保持平衡。由于汽轮机在检修、安装和运行中存在的问题,使调速系统在开机过程中常会出现一些异常情况,文中针对汽轮机调速系统的基本构造对常见故障及处理进行分析,期望能为相关的研究提供借鉴。The turbine speed control system is used to adjust the steam flow into the turbine to keep the balance between the turbine output power and the load power.Due to the problems in the maintenance,installation and operation of the turbine,the speed control system often has some abnormalities during the start-up process.In this paper,the basic structure of the turbine speed control system is analyzed for common faults and treatment,which is expected to provide reference for the relevant research.
