Design Of Distribution Automation Communication System Based On EPON

Nowadays,the rapid development of social science and technology continues to promote the progress of power automation system,but it also puts forward more severe requirements for its electronic information and control technology.Distribution is a part of providing services directly to power customers,so distribution automation will provide power customers with more high-quality power supply.State Grid Corporation of China insists on building a smart grid with future characteristics,which has strong interactive automation and digital information function.It realizes the full coverage of power production,transmission and use,and shows the intelligent and strong characteristics of the power grid.At present,the backbone network of power grid is becoming stronger and stronger,and the access network is stagnant.The feeder information data of distribution network is an important basis for the realization of distribution automation.In order to realize the reliability of distribution network,the operation instructions of dispatching control center must be accurately transmitted to the terminals installed by distribution equipment,and the data information and operation status of distribution equipment collected by these terminals can be timely and accurately fed back to dispatching control center,This also directly affects the safe and stable power consumption of the majority of power customers,and the communication system plays a key role in the data command transmission in the distribution automation system.The main research aspects of this paper are as follows:First,through the research of distribution automation system,clarify its functions and understand its basic composition.After a detailed understanding of the distribution automation system,its communication system is studied.According to the functions that distribution automation should have,this paper studies how the communication system as distribution automation system should be composed and meet what needs,and selects the most suitable access mode and communication mode.Second,deeply understand the principle of EPON(Ethernet passive optical network)technology,clarify its structural composition,conduct a detailed study on its access mode as the communication system of distribution automation system,and clarify whether the information communication system of distribution automation system can use EPON to realize various functions.Third,analyze the current situation and existing problems of various distribution network equipment in the power supply area of the company,clarify the technical requirements of distribution automation system in Manzhouli area for communication system,and deeply compare and study the probability of failure in each network.The topology of distribution network in Manzhouli region can be satisfied by EPON Technology.It is determined to adopt EPON Technology to realize the information communication system of distribution automation system in Manzhouli region and the networking mode of "hand in hand" to realize an efficient and safe distribution automation data transmission environment.A set of implementation scheme is designed for the information communication system of distribution automation system in Manzhouli region,Reduce the time for manual troubleshooting and line inspection of distribution network.
