Research on Substation Intelligent Diagnosis Technology Based on Secondary Cable Circuit Modeling

Because of the lack of secondary cable circuit model, the information model of the intelligent substation is incomplete. It is not only unfavorable to the comprehensive on-line monitoring and operational diagnosis in the elligent substation, but also hindered the information development of intelligent substation. In this paper, for the secondary cable circuits, a modeling method is proposed. At the same time, the configuration process is designed. Through the secondary cable circuit model file and visualization tools, the multidimensional visualization of the secondary cable circuit of intelligent substation is carried out. The secondary cable circuit information model is associated by mapping the information model with the communication model in the SCD file to the secondary cable circuit model. Based on this, the online monitoring and intelligent diagnosis of the secondary cable circuit can be achieved in the intelligent substation.
