Intelligent systems of mass data acquisition in power grids

This paper is describing the issues of data collection in power distribution networks. It discusses the posibilities of data communication over wide area networks using the communication protocol IEC 60870-5-104, used in power distribution systems for transmission of information over IP networks. Thesis presents 4 technologies, suitable for data collection, with respect to the use of existing infrastructure of the utility. It focuses on design of appropriate data types in correspondence with used IEC 60870-5-104 protocol, and estimates the minimum data requirements for transmission, through proposed hierarchical network, with collecting data concentrators. For verification of given design, simulations are carried out based on proposed data loads with subsequent analysis of network load and transmission delays. Consequently, the results are analyzed and selected parts of network optimized for improvement od selected results, of which causes of formation are discussed in debate
