摘　　要：针对传统数据库技术难以满足电力系统需求的情况,本文设计了一种分布式数据库(SH_MenDB),该种数据库的索引结构是在平衡二叉排序(AVL)的基础上建立的。首先,介绍了分布式数据库的概念;其次,详细分析了内存数据库的设计;再次,设计了内存数据库的系统结构;最后,通过应用事例介绍了分布式数据库(SH_MenDB)在变电站自动化系统中的服务方式。Aiming at the situation that traditional database technology is difficult to meet the needs of power systems,a distribution is studied and designed SH_MenDB,whose index structure is mainly established on the basis of balanced binary sorting(AVL).Firstly,the concept of distributed database is introduced.Secondly,the design of the memory database is analyzed in detail.Thirdly,design the system structure of the memory database.Finally,introduce the distribution through application examples the service mode of SH_MenDB in substation automation system.
