Research On Topology Identification Of Distribution Station Area Based On Internet Of Things Technology

With the development of IOT,power grids with voltage levels above 10 k V have basically possessed a relatively high level of automation and obvious features of smart grids.The low-voltage distribution network is at the end of the entire power grid.It has the characteristics of wide distribution,complex power supply environment,and difficult operation and maintenance.There has been a lack of effective operation and maintenance monitoring measures.As the basic element of the power supply system,the distribution station area is an important component of the distribution Internet of Things.The accurate topological relationship of the low-voltage station area is of great significance for the information collection of power users,and helps to improve the intelligence of the low-voltage distribution network.Level.This paper studies the overall architecture of the distribution Internet of Things,analyzes the topology type structure and identification requirements of the distribution station area,and at the same time studies the dynamic identification strategy of the distribution network topology and conducts simulation verification.On this basis,in response to the identification needs of the household change relationship and hierarchical relationship in the distribution station area,combined with the principle of power line carrier communication and power frequency communication,as well as the applicability analysis of the Internet of Things protocol,a converged power line based on the Internet of Things Co AP protocol is proposed.Communication technology.In order to realize the low-voltage topology identification scheme based on the Internet of Things Co AP protocol and power line communication technology,and to improve the accuracy of the distribution network topology connection,the design ideas of the topology identification module and the hardware design packaging work are studied,and the core unit topology identification module design is completed and verified Show.With the help of Nanjing Jiangbei IOT demonstration area project,we select relevant typical stations and districts,implement the transformation of low-voltage distribution network intelligent stations and districts,realize the low-voltage topology function,obtain the accurate household transformer and hierarchical corresponding relationship,form a complete network diagram of Station District topology relationship,realize the extensive interconnection of stations and districts,and comprehensively improve the perception,integration and intelligent application of distribution IOT,Realize the lean management of distribution network,improve the satisfaction of power users,provide strong support for the maintenance of low-voltage distribution network,provide low-voltage perception ability,improve the reliability of power supply and lean management of substation area,and establish the foundation for more advanced applications of distribution network.
