Recognitionflow of substation topological relationship based on power big data technology
With the deployment of intelligent collection systems in power networks,intelligent fusion terminals installed in the station area can provide cloud technology and edge computing related data for topological relationship recognition.A method of identif-ying topological relations between stations based on fusion terminal identification is presented.First,the principles and algorithms of topology recognition technology are analyzed,the advantages and disadvantages of each method are analyzed,and a comprehensive recognition method of knowledge graph,Pearson algorithm and big data analysis is proposed.The boundary conditions of the station topology recognition are given,and the implementation steps of the method in this paper are explained.Finally,an actual calculation example is used to simulate and analyze the topology recognition results of the additional protective device with measuring residual cur-rent.
