摘　　要：变电站内设备在线监测传感技术已经相对成熟,但其上送的数据相对专业,且设备状态改变是一个渐变过程,从数值上看这种变化是缓慢的,不易察觉的。如何及时发现这种变化,并通过直观的方法展示出来,成为成功应用在线监测技术的关键。提出了一种方法,通过评价计算程序对多种数据来源,包括实时数据、准实时数据及离线数据,进行分析处理,将变电站内设备状态以关键绩效指标(KPI)形式展现出来。该技术已经应用于多个智能变电站,取得良好效果。The technology of online monitoring for electrical equipment is mature, but the data the system provided is too professional to read. Also the course of electrical equipment status change often lasts very long time. The changing in numeric is too small to notice the problem of equipment. By acquiring and processing different kinds of data, such as real-time data, historic data, off-line data from management information system and manual intervention data, this paper applies key performance indicator （KPI） in online monitoring system to provide more readable results of electrical equipment status. The new system has been applied in many smart substation and got positive response.
