摘　　要：基于软测量图谱变化检测技术,研究了其在变电站状态智能分析中的应用。采用软测量技术对智能变电站状态图谱监测系统的接口分级、IEC61850信息模型、图谱变化监控系统、图谱状态监测系统结构进行研究,同时分析了软测量智能图谱分析关键技术支持向量机SVM法、设备软测量特征分析、典型场景数据库的建立。结合变电站的实际应用,对变电站的两个典型场景的图谱进行建模,通过两个典型场景区域实现对图谱变化异常情况的监控与处理,为今后软测量的图谱变化检测技术在变电站状态智能分析中的应用提供参考。According to the spectrum change detection technology based on soft measurement,its application in substation condition is intelligent analysis studied. The soft measurement technology is used to study the monitoring system interface classification,IEC61850 information model,spectrum change monitoring system and structure of the intelligent substation state spectrum monitoring system. The key technologies（support vector machine（SVM） method,soft measurement feature analysis of equipment,establishment of typical scene database）of the soft measurement intelligent spectrum analysis are analyzed. In combination with the practical application of the substation,the spectrum of two typical scenes of substation was modeled. The abnormal situation of spectrum variation can be monitored and treated with two typical scene regions,which provides a reference for the application of spectrum change detection technology based on soft measurement in substation state intelligent analysis.
