Research On Operation Quality Of Power Communication Network Based On Service

With the development of smart grid and global energy Internet,power system has gradually developed into material-information fusion,human-computer fusion,virtual integration,self-organizing,self-learning power service giant system,so more and more information needs to be transmitted.The requirement of real-time and reliability of information transmission is more and more high.As the key of power network information transmission,it is very important to analyze it.The electric power communication network has obvious industry characteristic,as one of the key support of the power service giant system,the service category increases rapidly,the network topology structure becomes more and more complex,therefore,based on the service,the operation quality of the electric power communication network is studied.It is of great significance to accurately reflect the operation quality of the network.Based on the summary and analysis of the current domestic and international research status in the field of power communication network operation quality,this paper determines the evaluation index of power communication network operation quality,so this paper is mainly based on service distribution and routing quality.The operation quality of electric power communication network is studied by two kinds of research indexes: service failure and influence.In view of the service distribution and routing quality index,the service risk balance degree is chosen as the service distribution measure,and the shortest path fit degree is chosen as the route quality measure,so as to measure the service distribution equilibrium degree and the service operation efficiency of the electric power communication network.Thus,a method for evaluating the operation quality of power communication network based on service distribution and routing quality is obtained.In view of the service failure and influence index,the whole network service failure index and the whole network service influence index are selected as the service failure and influence measure,considering the channel service type and the channel rate factor synthetically.Through the analysis of different failure scenarios and all the possible situations under the failure scenario,a method for evaluating the operation quality of power communication network based on service failure and influence is obtained.The validity and feasibility of analyzing the operation quality of electric power communication network based on service are verified by simulation and analysis.
