摘要(Abstract):
"输变配低"电网拓扑管理是供电企业GIS系统不可缺少的功能之一。着重讨论了GIS系统如何基于IEC61970电力系统CIM模型建立电网拓扑的方法和技术,介绍了CIM、拓扑包、拓扑模型与实例、拓扑的"表"表示及其在ORACLE数据库和内存中的实现及相应存取方法。
The network topology management of power transmission,transformation and distribution and low voltage systems is an indispensable function of enterprise-level Geographic Information System(GIS) for power supply bureaus.This paper discusses the methods and techniques of building the GIS network topology based on IEC 61970 CIM model and introduces the CIM,topology package,topology model and cases,topology table presentation and realization in ORACLE database and corresponding memory access methods.
