IEC 61850标准作为变电站出站远动协议的可行性分析

叙述了建设一体化电网运行系统以及调度中心与变电站之间上下数据贯通的必要性,分析了上下贯通所面临的数据模型、图形(接线图)、传输协议、源端维护与订阅/发布等问题,提出了采用IEC 61850标准作为出站协议的基本原则、建模方法、服务实现细节,在基于IEC 61850标准的变电站出站协议的基础上叙述了IEC 61850标准与公共信息模型(CIM)之间的转换规则以及源端维护和订阅/发布的实现方法。

Feasibility Analysis of IEC 61850 Used as Substation Telecontrol Protocol

The necessity of building an integrated smart power network dispatching automation system is proposed.In addition,the necessity of integrated data communication between dispatching center and substation is presented,and the analysis on the problems of IEC 61970 and IEC 61850 data model,substation’s diagram,telecontrol protocol,maintenance in the substation,subscribing/publish is also presented.The basic principles,the modeling method and communication service of telecontrol protocol based on IEC 61850 are proposed.On the basis of IEC 61850,the rule of model change between IEC 61850 and IEC 61970,realization method of maintenance in substation and subscribing/publish are put forward.
