摘　　要：转速作为水电站水轮发电机组的重要基础参数,直接参与到机组的正常开停机流程控制、事故停机流程执行以及机组状态判断等重要过程,一旦转速测量出问题,后果将不堪设想。以某水电站的转速测量系统建设为例,详细介绍了该系统的结构,并分析了两起转速测量装置相关的事件;最后,针对电站实际情况,提出整改措施,旨在消除安全隐患,保证机组安全稳定运行。Rotational speed,as an important basic parameter of hydro-generator unit,is directly involved in important processes such as normal start-up and shutdown process control,emergency shutdown process execution and unit status judgment.Once the rotational speed measurement is wrong,the consequences are unimaginable.Taking the construction of rotational speed measuring system of a hydropower station as an example,this paper describes the structure of the system in detail and analyses two events related to rotational speed measuring devices.Finally,according to the actual situation of the power plant,the rectification measures are put forward to eliminate potential safety hazards and ensure the safe and stable operation of the unit.
