摘要
针对当前各种基于IEEE标准电力系统暂态数据交换通用格式(COMTRADE)的故障分析软件无法进行自动在线故障分析、不能有效地与故障信息系统融合的现状,采用多种跨平台技术开发了一套基于COMTRADE的可跨平台在线自动故障分析软件系统。运用了基于可扩展置标语言(XML)配置文件驱动的设计原则,采用STLport和宏技术实现了可跨平台的最简COMTRADE解析算法,利用QT4完成了可跨平台的图形绘制及其图片生成技术,采用Xerces和Xalan实现了可跨平台的XML解析及其转换,可生成HTML,WORD和PDF格式的故障报告,扩展了突变量检测算法,实现了多个故障起始数据位置的检测。讨论了系统中基于选举的可靠故障选相算法,介绍了单端、双端测距算法的选用原则。该软件已与国内多个不同厂家的故障信息系统融合,投入运行。
In view of the inability of current fault analysis software based on COMTRADE to effectively conduct on-line automatic fault analysis and integrate with the fault information system, a set of cross-platform on-line automatic fault analysis software system based on COMTRADE is investigated and implemented using a number of cross-platform technologies. Based on the design principle of XML technology, it uses STLPORT and Macro technology to realize the cross-platform and simplest COMTRADE parse algorithm, QT4 to realize the cross platform graphics drawing and picture generation technology, Xerces and Xalan to realize the cross-platform XML parse and transform, thereby generating the fault report in the format of HTML, WORD and PDF. It has expanded the incremental quantity detection algorithm and realized position detection for multi-fault initial data. The reliable fault phase-selection algorithm is discussed, the selection principle of single-terminal and double-terminal fault location algorithms is described. The system is successfully integrated with many fault information systems from different manufacturers, and has completed numerous automatic fault analyses after putting into operation.
