Design And Application Of Distribution Network Communication System Of A City Power Supply Bureau Based On EPON Technology

In order to improve the reliability and quality of power supply,expand the power supply capacity and ensure the efficient and economic operation of the power distribution network,one of the key means is the automation of power distribution network,which is also an important basis for the Smart Grid Construction.The construction of smart grid automates the distribution grid.obtain a new connotation,and thus establishes a new development idea.Distribution network communication system plays an important role in distribution automation.The efficient configuration of communication means can ensure that dispatching instructions can be accurately transmitted to the distribution terminal equipment,and the parameter information and results of terminal equipment execution instructions can also be fed back to the dispatching center.Considering the distribution network terminal equipment assembly has the problems of wide geographical distribution area,many network nodes,high data transmission and quality requirements,so the distribution network communication system networking design is particularly critical.EPON Technology has the characteristics of simple operation and maintenance,flexible networking,wide coverage area,wide frequency band,reliable and safe network operation,which is the most frequently used technology in the construction of intelligent distribution network.Based on the case study of the distribution network system of a city's power supply bureau,this paper focuses on the design and application of the communication system of the distribution network of a city's Power Supply Bureau based on the application of EPON Technology.On the premise of describing the background and significance of the topic,this paper combs and reviews the frontier research results of related topics at home and abroad,briefly analyzes the EPON Technology principle,so that the writing of this paper can obtain theoretical support.At the same time of investigating and mastering the actual situation of a city's power supply bureau,deeply analyzing the operation status and exposed defects of its distribution network,based on the practical work,analyzing the communication system needs of the distribution network construction,thus proposing and improving the distribution network communication system scheme design,which involves the distribution network communication system design,system security design and other sides,including the system design framework It is divided into backbone layer and access layer.In the application practice,the application effects of the overall scheme,channel design scheme and typical design of optical cable are evaluated respectively,and the final conclusion is obtained.The evaluation of application results shows that the distribution communication system based on EPON Technology can meet the actual needs of distribution automation,and has significant value in improving the standardized management of distribution information,improving the efficiency of information transmission and exchange,safety and reliability performance.The design of this application scheme has certain reference significance for theoretical research and practical work.
