电厂的辅助设备数量多、分布广,其运行的可靠性关系着电厂的安全与经济性。大庆石油热电厂采用MD2000总线式设备运行状态在线监测诊断系统,较好地解决了系统扩展、在线监测、故障诊断、设备保护、施工量大、成本高等问题,可早期发现设备的故障并及时处理,有效防止事故扩大。同时通过对设备故障状态的趋势分析,为状态维修提供科学依据。 The number of auxiliary equipment in power plants is large and distributed widely. The reliability of their operation is related to the safety and economy of power plants. Daqing Petroleum Thermal Power Plant adopts the on-line monitoring and diagnosis system of running status of MD2000 bus equipment to solve the problems of system expansion, on-line monitoring, fault diagnosis, equipment protection, large construction cost and high cost, and can early detect the failure of equipment and handle it in time, Effectively prevent the accident from expanding. At the same time, through the trend analysis of the equipment fault status, provide the scientific basis for the status maintenance.
