Research On 10kV Integrated Automation System Of Distribution Network Based On GIS Technology

With the progress of society,human dependence on electricity has gradually increased.In the entire power system,the distribution network occupies an important position.In the process of the government's continuous promotion of urbanization,the scale of the distribution network has gradually expanded,and the management of the power grid has become more complicated.If automation and GIS technology can be introduced,it will promote the double improvement of the quality and efficiency of power grid management and reduce the manual workload.The voltage levels of the distribution network are different.The 10 k V power grid is the closest to the user end.Therefore,its number and coverage are wide.Its operation effectiveness and quality directly affect the reliability of the entire distribution network.In this subject,the author designed a 10 k V distribution network integrated automation system integrated with GIS technology to achieve the automatic management of the 10 k Vdistribution network.First,the research background and significance of this topic are explained,and the actual situation of the distribution network automation system worldwide and the problems it faces are introduced.Explore the architecture and technology of this system.Based on the understanding of the distribution network structure,the factors involved in the 10 k V distribution network automation system were discovered,and the analysis of how to choose a suitable communication method was performed.Introduce the role and value of GIS technology in distribution network automation,discuss how to use this technology to obtain information,and complete the overall design of the distribution network automation system based on GIS technology.In this process,design the electrical scheme of the distribution network automation system,select the appropriate wireless information transmission method,and solve the problem of how to obtain location information.The communication node design of 10 k V distribution network automation system is described in detail.After completing the needs analysis of the communication nodes,design the implementation plan of the optical fiber private network communication network and the private network communication implementation plan,focusing on the field communication access unit,micro-controller selection,and the design of various circuits.Finally,the overall scheme of distribution network automation system based on GIS technology is introduced.After listing the technical requirements for information system integration,the paper discusses how the GIS system and the distribution network automation system can be seamlessly connected,and explains the information exchange between the two.The integration of distribution network automation system,production PMS system,and centralized control system is emphasized.The thesis successfully introduces GIS technology into the distribution network automation system,improves the intelligence level of the 10 k V level power distribution network,effectively solves the problems of system integration,equipment and system communication,and finallysuccessfully develops a set of integration.Integrated automation system of 10 k V distribution network based on GIS technology.After the system is put into operation,the 10 k V-level power grid can run more stably,effectively saving management and maintenance costs.
