摘要
本文在研究智能变电站在线监视对象的基础上,重点进行了变电站二次系统的健康分析和状态统计。设计了变电站二次系统状态估计的整体框架,建立了二次系统的状态方程。进而以信息流模型为载体,研究二次系统的运行方式辨识和故障诊断方法。最后具体阐释智能变电站在线监视的状态评估方法。
Based on the study of intelligent substation on-line monitoring object,the paper focus on the secondary substation system health analysis and status statistics.It designs the overall framework of the secondary system state estimation of substation and establishes the state equation of the secondary system.The information flow model is used as the carrier to study the operation mode identification and fault diagnosis method of the secondary system.Finally it elaborates the state evaluation method of intelligent substation on-line monitoring.
