水电厂最优维护信息系统的数据层次性组织策略

针对水电厂设备维护的研究现状提出了水电厂维护域的通用功能参考模型;介绍了水电厂最优维护信息系统的分布式网络体系结构;研究了一种数据层次性组织和存储策略,该策略对设备故障诊断和维护决策的数据信息进行了系统分类和分布存储,具有数据组织模式清楚、存储格式合理、数据使用方便等优点,既减少了数据冗余又能满足最优维护信息系统中各层次的功能需求和电厂不同层次用户的使用需求.

Data Hierarchical Organized Strategy of Hydropower Plant Optimal Maintenance Information System

The general functional reference model in maintenance domain of hydropower plant is brought forwards according to the research status of hydropower plant equipment maintenance.The distributed network architecture of optimal maintenance information system is discussed.And then,a kind of data hierarchical organized and stored strategy is studied.By using this strategy,the data and information which use to do fault diagnosis and to make maintenance decision are classified systemically and stored distributed.It has some advantages such as clear data structure,reasonable storage format and convenient data using.This strategy not only can reduce redundancy of data storage,but also can meet the different functional requirements of all levels in optimal maintenance system and the needs of different users in hydropower plant.
