Modelling and implementation of Single Line Diagram data in IEC 61850 environment

The aim of this paper is to improve the automation processes of electrical power substations based on IEC 61850 standard, with the focus on data management related to data structure, path, and communication model. When modelling substations items a simple and clear approach is necessary to effectively match binary or analog data from the switchyard with the IEC 61850 data object model. The study is made by simply transforming data from a single line diagram and its functionalities into object model by explaining its hierarchy structure and how to use it to create an operational process interface. This possible through the three key components of the IEC 61850 standard: Client-Server based on TCP/IP MMS (Manufacturing Messaging Specification) which perform the monitoring and control functions, GOOSE (Generic Object-Oriented Substation Event) protocol used in applications between IEDs (Intelligent Electronic Device) like interlocking signals and trip messages and Sampled Values (SV) protocol used for fast transmission of analogue values over the network.
