基于状态检修的火电厂重要辅机维护模式

Maintenance Mode of Important Auxiliary Engine in Thermal Power Plant by Condition Based Maintenance

随着火力发电市场形势日益严峻,如何提高发电机组的可靠性、减少检修费用和延长大修周期成为各大发电集团研究的课题。华能上海石洞口第二电厂作为华能国际电力股份有限公司状态检修试点单位,在原有检测设备的基础上,通过少量的系统改造,对不同的电厂设备进行不同重视程度和方式的检测,通过可靠性预测与评价方法,判断设备故障状态的早期征兆以及故障的识别、定位、严重程度和发展趋势,进行有针对性的设备维护,防患于未然,提高辅机可靠性,从而确保发电机组能安全、稳定、长周期的运行。

Monitoring the operating state of important auxiliary machinery in different periods and modes.Through related diagnostic methods,reliability evaluation methods and life prediction methods,estimate the state of the equipment and the early signs of fault identification,judge the fault position and its severity and the development trend of the fault.To nip in the bud,the targeted maintenance is carried out to prevent and improve the reliability of the equipment so as to ensure safe,steady and long period operation of the generator units.
