Design And Research Of Communication Scheme Of Distribution Network In Jinzhong Area

With the rapid development of urbanization,the transformation of distribution network is promoted,and the intellectualization and automation of distribution network are basically realized.In the intelligent and automatic distribution network,a large amount of data needs to be collected and used,which requires high real-time,high-efficiency and reliability of communication network,so as to ensure the correctness and effectiveness of data information collection,transmission and control instructions.Distribution network communication system is the basis and guarantee of the whole distribution network operation,so the reliability and firmness of the network directly affect the operation quality of the distribution network.This paper mainly on the design of a regional distribution network access scheme,to provide a reference for the design of the regional distribution network communication system.Firstly,this paper studies the background and significance of distribution automation system and its communication system,and points out that although Jinzhong Power Grid communication network has taken shape,with the development of power automation technology and the increase of non telephone business,various disadvantages of existing communication network begin to expose,such as low data transmission rate and small equipment capacity,which can not meet the requirements of Jinzhong Power System The development of automation technology.On this basis,the paper analyzes the requirements of Jinzhong distribution network communication system,and further compares and analyzes the advantages and disadvantages of different communication schemes.This paper focuses on the design of Jinzhong distribution network communication system access layer and backbone layer communication network,and gives the construction scheme of Jinzhong distribution network communication system,including its construction ideas,network structure,site equipment configuration and network construction.In order to verify the correctness of the design scheme,three distribution networks are selected to test their communication network performance.The test contents include the throughput,delay and packet loss rate of the communication system.The test results verify the feasibility of the communication scheme.
