摘　　要：本文针对某抽水蓄能电站2号机组因调速器一路导叶反馈传感器故障导致的非计划停机事件,结合GB/T32574《抽水蓄能机组自动化系统技术条件》及DL/T496《水轮机电液调节系统及装置试验规程》等标准规范,深入分析了调速器系统在信号采集、逻辑判断环节的故障机理。研究揭示出现有控制逻辑存在三点不足:单通道反馈失效直接触发停机保护、传感器自诊断周期过长、缺乏故障状态下的穴余切换机制。In this paper,in view of the unplanned shutdown event caused by the failure of the guide vane feedback sensor of the governor of unit 2 of a pumped storage power station,combined with GB/T 32574"Technical Conditions for Pumped Storage Unit Automation System"and DL/T 496"Test Regulations for Hydraulic Hydraulic Regulating System and Device of Hydraulic Turbines",the failure mechanism of the governor system in the link of signal acquisition and logic judgment is deeply analyzed.The study reveals that there are three deficiencies in the control logic:the single-channel feedback failure directly triggers the shutdown protection,the sensor self-diagnosis cycle is too long,and the redundant switching mechanism in the fault state is lacking.
