摘要(Abstract)：
湖州地区变电站油色谱在线监测及辅助诊断系统是利用PI实时数据库从SCADA系统中提取变电站主变压器油色谱实时数据,用PrecessBook的相关工具对这些实时数据进行分析,实现油色谱在线预警和历史数据查询功能,同时充分利用PI数据库的编程功能,通过后台运算进行初步故障诊断,为维护电网的安全稳定运行提供技术保障。
The real-time data of main transformer oil chromatograph of the substations are extracted from the SCADA system by means of PI real-time database in the online monitoring and assistant diagnosis system for oil chromatograph of the substations in Huzhou area.Through the analysis on these data with PrecessBook,online early warning and historical data query of oil chromatograph are achieved.It also takes full advantage of the programming functions of the PI database to conduct the preliminary fault diagnosis through background operation and provides technical support for maintaining the safety and stability of the grid.
