[Abstract]:In the safe operation of the power grid, the development of substation automation system for its economy, security plays an important role, with the acceleration of the information process, the structure of the grid has become much more complex. And the amount of information needs to be conveyed has become more huge, therefore, the network requirements for substation information systems are further improved. Based on this form. It is very important to construct a set of communication network which can realize information standardization and equipment operation facilitation. The main content of this paper is the research and design of substation automation communication network. The first part is the introduction, to the research background and significance, the domestic and foreign research present situation, the research main content and so on carries on the detailed introduction, in order to enrich this paper the theory foundation; The second part is the basic overview of substation automation communication network, from the substation automation system, substation automation, substation integrated automation network structure IEC61850 standard technical characteristics. The communication network, network, process layer network and unified communication network of substation automation system based on IEC61850 are summarized in order to better understand these basic concepts. The third chapter is the construction of substation automation communication protocol and model. The characteristic requirements of substation automation communication network and substation automation communication function are introduced. Secondly, the IEC61850 standard implementation process, function modeling process, data modeling, communication service mapping, network load modeling, periodic information modeling, burst information modeling. Modeling and conformance testing of file transfer information; Chapter 4th describes the related concepts of substation automation communication network design, first describes the substation networking scheme design, networking equipment selection and requirements, substation network diagram. Secondly, the topology of substation automation communication network is designed to describe the substation automation communication network network from the only network of the whole station and the two-layer independent network. Chapter 5th is the simulation analysis of substation automation communication network. Firstly, the simulation software is introduced, and the process layer network and unified communication network are simulated and analyzed. Finally, the simulation results are described. Part 6th is the full text of the highly summarized, and prospects. This paper according to the IEC61850 involved in the idea of hierarchy. This paper presents the substation automation communication network networking mode of the whole station unique network and two-layer independent network, thoroughly solve the substation communication mode and data structure is not unified, internal information sharing difficulties. The problems of poor interoperability among devices and low data utilization ratio ensure the real-time performance of data communication in substation automation system effectively and further expand the development space of substation communication network.
