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.
