Failure Diagnosis System for a Steam Turbine Regulating System

汽轮机调节系统的故障诊断装置可以记录汽轮机调节系统关键参数的变化趋势 ,实现了汽轮机静特性在线计算、滑阀卡涩状态检测以及调节系统振荡故障诊断的功能 ,可以大大提高调节系统的运行安全性 ,对系统预测维修起着积极的作用。

With the help of the failure diagnosis system of a steam turbine regulating syst em it is possible to record the variation trend of the key parameters of the sai d system. The realization of such functions as the on line calculation of steam turbine static characteristics, the detection of pilot valve stuck status and t he regulating system oscillation failure diagnosis can result in a significant e nhancement of the operating safety of the regulating system. Moreover, the above also plays a positive role in the preventive maintenance and repair of the regu lating system.
