Prototype Design of Graphic System Configuration Tool for Intelligent Substation Based on IEC 61850

为了实现基于IEC 61850的系统配置功能,加强对保护智能电子设备(IED)之间虚拟交互消息等的描述,文中研究了一种基于IEC 61850的变电站图形化系统配置器原型系统。该系统包括配置主界面、可扩展置标语言(XML)解析与变电站配置语言(SCL)语法验证模块,以及3类交互信息(逻辑节点(LN)内部保护逻辑、IED内各LN之间的配合逻辑关系、不同IED中相关LN之间的虚拟交互消息)配置图形化界面等模块。设计了一次接线图、二次设备配置等工具箱,给出了图元绘制与拾取、以可缩放矢量图形(SVG)格式存储图形文件、图形化配置不同IED内相关LN之间虚拟交互消息等关键技术的实现方法。该配置器原型系统实现了主要功能,为智能变电站的配置开发和测试提供了一定的参考。

In order to implement the system configuration function based on IEC61850and strengthen the description for virtual interactive messages among protection intelligent electronic devices（IEDs）,a kind of prototype of graphic system configuration tool based on IEC61850for substation is studied.Function modules of the system include the main user interface,extensible markup language（XML）analysis and substation configuration language（SCL）syntax verifying modules,as well as three kinds of interactive information configuration modules,i.e.,internal protection logic relationship in a logical node（LN）,the coordination logic relationship among LNs in an IED,the virtual interactive messages among LNs of different IEDs.Some toolboxes that include primary electric wiring diagram and secondary equipment configuration are designed.Implementation methods of the key techniques are described,such as drawing and picking of graphic elements,the storage of graphic files with scalable vector graphics（SVG）,the graphic configuration of the virtual interactive messages among different IEDs.The main function of prototype graphic configuration system has been implemented.It provides a reference for the configuration development and system testing of intelligent substation.
