Research On The Scheme Design Of A City Distribution Network Communication System

In the power system,the distribution network automation management is an important development trend,which can give full play to automation technology,computer technology and communication technology advantages,improve the management efficiency and quality of distribution network.In the distribution network automation system,the distribution data communication network program design and construction is very critical work content.The distribution data communication network bears the distribution network of business data and operational status of the data communication and interactive functions.Therefore,in the process of distribution network automation,the data communication system design and construction work for the entire distribution network automation has an important impact.Under this background,the scheme design and implementation of distribution communication system in distribution network automation construction project of the power company worked in is studied deeply in this thesis based on actual project participation experience.In the research work,the design and construction of technical scheme for distribution network communication system of the power company is studied by the use of EPON passive cable communication technology and GPRS wireless public network technology through the local distribution network development and the current situation of the study.In the study work of this thesis,there are three parts in the work.First of all,the current distribution of the relevant concepts of communication network to introduce,including the distribution network automation and commonly used centralized communications technology.Then,based on the actual research results,the basic situation of the distribution communication system and the design and construction of this program to carry out the inspection,including the city’s distribution network overview,distribution communication system overview and distribution of communication systems Goals and so on.Finally,based on the above work from the communication system construction and application program,communication system construction and transformation program and safety protection network construction program point of view,focusing on the use of EPON and GPRS communication technology on the distribution of communication system networking program detailed design and presentationThe network design and construction scheme of power distribution communication system designed and proposed in this thesis could provide the advanced reliable data communication support for the intelligent distribution network.
