Network Topology Analysis For Statutes Of The Electric Power Communication Network And Evaluation System

Power communication network reliability has a close relationship with the normal operation of the power grid, power communication network is a private network for grid services, the infrastructure of the power system. With the improvement of people’s living standards, the demand on the power system increases, thereby increasing reliability requirements for the electric power communication network. In the paper, power communication network is as a whole system, the establishment of the electric power communication network reliability evaluation process to build power communication network reliability evaluation model according to the process, the index system reliability measures, the final power communication network reliability evaluation procedures, the development of the electric power communication network reliability cvaluation software.This paper is in the context of the project of "the Yunnan power communication network reliability evaluation procedures", in the pre-project research achievements, inherited the reliability of electric power communication network layered architecture, reliable electric power communication network assessment model is divided into four levels-network topology, site equipment, environment variables, and management factors. From the four modules, based on the information and data provided by the grid company, to extract the underlying index, induction and classification, to enrich power communication network reliability evaluation index system, the preparation of the electric power communication network reliability evaluation procedures.Combines complex network theory, simulation of the actual Yunnan Power Grid fiber optic backbone basis of property values, and its random attack and intelligent attack, to test under attack, the network topology shown invulnerability. According to the procedures, network topology module routing topology reliability numerical simulation calculation.On the basis of theoretical studies, the subject is based on NET and SQL Server database technology developed practical, simple, convenient power communication network reliability evaluation software. The software includes user management, database management, network topology management, basic data import, Custom Weight set, reliability and timely evaluation module, reliability, multi-dimensional statistical analysis module, a timely and effective assessment of the reliability of the electric power communication network, to improve power communications network management efficiency and management level.
