Research And Design Of Communication System In Distribution Automation Construction In A District

The distribution automation system mainly refers to the centralized management system which coordinates,monitors and controls all kinds of remote terminals in the power system in real time.In the distribution network automation system,the distribution network communication system is a reliable guarantee to ensure the normal operation of the distribution network automation system,which can better ensure the data collection,operation state change and optimize the implementation of the distribution network.For this reason,the rationality of the communication system can have the most direct impact on the operation quality of the distribution automation management system.This paper takes the distribution communication network of Yingde Power Supply Bureau in Qingyuan City,Guangdong Province as an example,based on the analysis of the geographical location,economic development trend,the current situation of distribution automation construction and the operation of communication network in this area,designs a supporting communication system suitable for the automatic construction of distribution network in this area,and verifies the feasibility of the design scheme through actual engineering cases ? The main research contents and achievements are as follows:This paper summarizes and analyzes the reliability status quo and key problems of the communication network under the jurisdiction of Yingde Power Supply Bureau.Based on the brief introduction of social economy and electric power communication network in Yingde City,this paper points out the weakness of supporting communication network construction in distribution network automation construction in Yingde City at present,and further analyzes the communication automation level in Yingde power grid,and it is known that the current communication automation construction can not meet the conditions of comprehensive real-time monitoring of distribution network operation status.According to the situation of distribution automation construction and distribution network communication in England and Germany,the distribution network communication system suitable for the transformation of distribution network automation in this region is designed.The design mainly uses optical fiber network as the main transmission means,builds a communication system based on Ethernet EPON Technology,supplemented by wireless public network,and finally builds a communication system suitable for the actual situation of distribution network automation construction in this region.Combined with the actual demand of Yingde Power Supply Bureau,it provides detailed and powerful decision-making support means and practical implementation scheme for the construction of distribution automation communication system in this area,and verifies the feasibility of the scheme through the pilot construction.According to the actual effect,it can be concluded that the scheme is practical and feasible,and the pilot implementation results for distribution automation transformation in this area The construction of credit has practical reference significance.Finally,through the acceptance test of the engineering implementation case of the design scheme,the receiving power and actual bandwidth of the terminal equipment are obtained,and a few terminals that fail to pass the test are studied and analyzed,and the improvement scheme is proposed.
