为满足智能变电站分析Comtrade格式录波的需求,设计并开发基于Comtrade档式和IEC61850文件传输模型的可视化故障录波分析系统.该软件能够根据IEC61850文传输模型,从智能电子设备中将Comtrade格式的录波文件下载到软件,解析后进行采样数据波形化显示,故障简报、事件报告、开入量列表化呈现,同时通过分层可视化逻辑显示提供系统了解逐层深入探究的录波分析方法,使录波更加直观便捷,科学精准.本文阐述可视化录波分析的总体架构和程序流程,着重介绍基于IEC61580文件传输模型的录波下载功能、采样数据分析算法,并对基于SVG可视化逻辑显示的具体实现进行详细介绍.%In order to meet the needs of recorded wave analysis in intelligence substation, the paper designs and develops the recorded wave analysis software based on QT. The software based on Comtrade format and IEC61850 file transfer model can download the Comtrade format wave file from intelligence electronic device, analyze the file, then display sample data, event report, and fault presentation graphically. Through the layered visual logic disply, the software provides the recorded analysis method which going from understand systematically to in-depth analysis, and makes the recorded wave analysis more intuitive, precision and scientific. This paper describes the overall software architecture and program flow of the recorded wave analysis, focuses on the function of downloading recorded wave file based on IEC61850 file transfer model, the sample data analysis algorithm, and describes software functions in detail.
