基于整体优化的状态维修策略与实践

COMPREHENSIVELY OPTIMIZED STRATEGY AND PRACTICE OF CONDITION BASED MAINTENANCE

介绍大连供电公司在设备维修策略方面所进行的探索及所取得的经验。实践表明,通过网络化的计算机综合管理信息系统(MIS),对设备状态进行跟踪管理和趋势分析,可早期获取设备劣化信息,为适时地对设备进行适度维修提供依据,可避免某些故障的发生。认为制定基于电网整体优化的维修策略,才能有效减少诸如变压器烧损这类突发性故障的发生。多级电网实时信息的集成将使运行电网的优化成为可能。

This paper introduces the study and experience of equipment maintenance strategy in Dalin Power Supply Company. The practice shows that through network based and computerized comprehensive management information system (MIS) and the follow-up management and tendency analysis to equipment states, the deterioration information of equipment can be early obtained, which provides basis for in-time and appropriate maintenance to avoid certain faults. It is recognized that only the comprehensive optimized maintenance strategy can effectively reduce contingencies, such as transformer burnt out faults. While the integration of multi-level real-time information enables optimization of power network operation.
