摘　　要：根据汽轮机DEH伺服控制系统安全设计和相关标准,提出了汽轮机DEH伺服控制系统冗余改造方案,大大减少了因伺服控制系统LVDT、伺服卡等装置配置不当造成汽轮机阀门波动的可能性,从而提高汽轮机DEH系统的可靠性。According to the design safety principles of a steam turbine DEH servo control system and related standards, a retrofit scheme was proposed for the system redundancy, which greatly reduced the possibility of the turbine valve fluctuations caused by improper configuration of the servo control system LVDT, the servo card or other devices, thus improving the reliability of the turbine DEH servo control system.

关 键 词：汽轮机DEH控制系统 双冗余控制 阀位反馈
