基于轻型目录访问协议的电力系统对象注册中心

摘要

当前,电网各专业系统对象命名和编码的方式存在差异,导致不同系统间交互困难。提出并实现了一种基于轻型目录访问协议(lightweight directory access protocol, LDAP)的电力系统对象注册中心,对全局对象进行统一的命名和编码管理,实现电网运行中全局对象命名和编码的标准化、统一化。测试表明,基于 LDAP 的对象注册中心可以有效解决对象命名和编码的差异问题,并相较于传统的关系数据库, LDAP 后端使用的键值对数据库在查询操作上具有更好的性能优势。%Objects term naming and encoding methods are different among various systems in power network. Such differences lead to interaction difficulties among the systems. An object registration center for power system based on lightweight directory access protocol (LDAP) is proposed and realized in this paper. The object registration center unifies all object terms and manages their encodings to a-chieve a standard and unified global objects term naming and encoding. The test shows that this object registration center can effective-ly eliminate the differences in object term naming and encoding. And comparing to the traditional relational database, the key-value database used by LDAP have better performance advantage in query operation.
