基于图数据库的电力设备全生命周期管理技术研究

Research on Power Equipment Life-Cycle Management Technology Based on Graph Database

电力设备作为电网公司的重要资产,其质量直接影响电网的运行水平,基于实际运行信息和检修信息对电力设备进行客观评价对于提升电力设备的运行水平意义重大。尽管电力设备制造企业(产业集团)拥有大量的供应商、产品、用户等信息,电网公司拥有大量产品设备运营信息,但受技术手段限制,不仅设备制造企业和电力公司之间的数据缺乏交流,企业内部的数据竖井化问题也非常严重,造成信息重复存储、更新不同步、关联性缺失、系统功能单一等问题。文章提出一种基于图数据库的电力设备全生命周期管理系统,借助图数据库将设备的技术参数、供应链信息以及企业信息高效整合,极大地提升了复杂关联数据的操作性能,实现了生产、物流、库存等供应链信息的快速查询、以技术参数为依据的电力产品精准推荐以及电力设备的全供应链质量追溯功能。

Power equipment is the most important asset of electrical companies and directly affects the operating level of power grids.Objective evaluation of power equipment based on actual operational and maintenance information can significantly improve the operational level of power equipment.Power equipment manufacturers(industry groups)have a huge amount of information for suppliers,products,and users,while electrical companies have detailed equipment operation information.Because of the limitation of technical means,not only the lack of data exchange between equipment manufacturing companies and power enterprises,the internal data silencing problem is also very serious,which may cause duplicated information storage,asynchronous update,weak connections between databases,and function singleness.This paper proposes an enhancement of power equipment life-cycle management(PLM)system,which uses the graph database to efficiently integrate the complete technical parameters,supply chain and enterprise information of the equipment to greatly improves the operational performance of complex associated data.Comparing with the existing asset management systems,the PLM realizes rapid inquiry of supply chain data,such as manufacture,logistics,and inventory,the accurate recommendation of power equipment based on technical parameters,and comprehensive quality traceability of power equipment.
