The application of IEC 61850 on integrated intelligent components for transformer

The paper describes a type of integrated intelligent components for transformer, which have been applied in the renewal project of Ji'nan substation in Jingzhou city in Hubei province, and discusses the network configuration, information model, internal and external communication interfaces. Components read metrical information from process level, implement data distribution between main and sub IEDs in PCI style, and communicate with station level directly. Based on IEC 61850, the components consummate the condition monitoring information model and multiple interfaces (Ethernet, RS485, etc.) for information exchange, achieving the goal of communication and information exchange with background system.
