Identification of Electric Power Losses on the Basis of Systematization of Registration Data

Abstract

Purpose of research. is cost reduction of electric grid companies due to development of information management system of commercial losses. Implementation of an information system provides information systematization and formation of electric power balances capable to output information about losses on various sites of network structure such as 0.4 kV air and cable power lines.Methods.Losses estimate method which uses summarized information about network schemes and loadings. This method includes calculation of electric power losses on the basis of losses dependence on total length and lines, total power and equipment received on the basis of technical parameters of lines and equipment or statistical data.Results.There is a problem with losses tracking of electric power on various voltage levels in many power supply organizations. It is connected as with lack of functionality in existing information systems of cuts formation on various levels of network structure and also with network structure maintenance on each connected subscriber. Electric power supply organizations have no opportunity to trace electric power transport systemically from supplying elements (tires of substations) to 0.4 kV air and cable lines of low voltage transfer. It happens due to hierarchy lack in existing structures of supplying elements. It is impossible to define on what network sites losses exceed admissible norms and manage them without registration data systematization.Conclusion.Information system was implemented on the basis of an objective which systematizes registration data and forms electric power balances on various levels of network structure. Review results (data collection) have information about alleged commercial losses on definite electric network sites.
