摘　　要：针对电网通信共享性较低的问题,提出了基于虚拟数据库的电网通信元数据模型设计,并制定基于HDFS的元数据管理准则、基于"发布-订阅"的电网通信元数据分发方案、基于HBase的电网通信元数据共享运作方案、虚拟数据库中电网通信表的构建方案,以此实现电网通信元数据高效管理。经实验验证,当某智能配电网数据通信系统应用所构建模型后,智能配电网数据通信系统实时性、通信网路服务质量、用户吞吐量与数据吞吐量、丢包率、响应效率均符合标准,且可为10 000个账户提供同时应用,共享性极高。Aiming at the problem of low sharing of power network communication,this paper puts forward the design of power network communication metadata model based on virtual database,and formulates the metadata management criterion based on HDFS,the power network communication metadata distribution scheme based on "publish-subscribe",the power grid communication metadata sharing operation scheme based on HBase,and the construction scheme of power grid communication metadata table in virtual database,so as to realize the efficient management of power grid communication metadata. The experimental results show that after the application of the model of an intelligent distribution network data communication system,the intelligent distribution network data communication system is real-time,communication network quality of service,user throughput and data throughput,packet loss. The rate and response efficiency are in line with the standard,and can be used at the same time for 10 000 accounts,and the sharing is very high.
