Operation Quality Evaluation Of Power Communication Network Based On Network Topology And Service

The power communication network is an important part of the power system.In recent years,with the rapid development of power system communications,the stability of power grids has increasingly depended on the reliable operation of power communications networks.Research on the operation quality of the power communication network is of great significance for the reasonable maintenance of the network,improving the network's invulnerability,and reducing the network's business losses.Since the normal operation of the power communication network requires a robust network topology and stable and reliable services,it is necessary to carry out a network operation quality evaluation based on topology and services for the power communication network.The thesis first analyzes the research results of power communication network operation quality at home and abroad,summarizes the evaluation methods of network operation quality;focuses on the analysis of power communication network and topological parameters,and introduces the business characteristics of power communication network.Secondly,K-order structural entropy is used as the evaluation index of the heterogeneity of the network structure,and the ratio of the sum of the structural entropy of different K values and the sum of the maximum structural entropy of different K values is used as the evaluation index to evaluate the topological quality of the network.A comprehensive evaluation of the global and local characteristics of the power communication network is provided.Then,based on the business perspective,the network operation quality is evaluated,and the relative reliability of the service is used to evaluate the quality of the service routing,which fully considers the impact of the shortest path between nodes on the business reliability.The business risk information entropy is used to evaluate the quality of the business distribution and fully consider the business.The impact of the transmission of the main and backup routing factors on the service distribution;the analytic hierarchy process is used to set the weight of the index to obtain a comprehensive index to evaluate the quality of service operation.Finally,simulation analysis was carried out through experiments to verify the effectiveness and feasibility of analyzing the operation quality of the power communication network based on topology and services.
