Planning Of Communication Network In Distribution Network For Zhaoqing District

With the rapid development of economy and electricity demand,Citizen have put forward higher requirements in terms of power supply reliability,power quality and related ancillary services.The traditional regulation technology and method of distribution network are lagging behind,Under the current situation of large power distribution,it is difficult to meet the management requirements.In recent years,with the development of automation and intellectualization of distribution network,Communication network extends further to distribution network,The number of communication nodes is increasing,Node distribution from centralized to decentralized development,The types of transmission information are more varied,Requirements for environmental adaptability of field communication devices are higher.The existing communication network of power system is difficult to support the demand of intelligent communication in distribution network.Therefore,using modern communication and computer technology and equipment to develop distribution network dispatching automation technology to improve the quality of power supply and operation economy,It is very important to improve the dispatching operation management level of distribution network.Based on the development of Zhaoqing distribution network as the planning background,Combined with the actual situation of the region,Research on the structure and function of distribution network communication network,Analysis of data transmission mode and its principle,Calculating the traffic flow of distribution network communication network demand,According to the traffic volume of communication service,A hierarchical communication network structure is proposed for design.In this paper,the distribution network communication network in Zhaoqing is divided into backbone communication network and access layer communication network,Backbone layer communication network makes full use of existing power communication network resources,The channel adopts optical fiber direct connection or MSTP mode,Form a semi mesh or mesh network;Access layer communicationnetwork chooses two-layer industrial Ethernet switch to form ring topology to form channel self-healing protection.Focuses on the data network optical fiber private network,Feasibility of hybrid networking scheme supplemented by wireless public network.
