Safety Testing And Comprehensive Evaluation Of PTN Based On Power Application

PTN technology is a combination of IP/MPLS,Ethernet and transmission network technology.As a good transmission and carrying technology in the future electric power communication network,PTN technology adapts to the development of diversification of the power grid business,IP,intelligent and broadband.But PTN has not been large-scale promotion and application,for whether its soft isolation effect on carrying security division business,system security,network attacks,network security,key performance index meets the requirements of the power grid and other related issues is inconclusive.Therefore,it is necessary to carry out the research of PTN security testing and comprehensive evaluation technology based on power application.Given the above issue,firstly,this paper investigate and survey the status of power application and bearing on PTN,analyse the security of PTN requirement based on power application,put forward the overall goal of constructing the key index system of power PTN safety performance evaluation and build the key index system of PTN security performance evaluation through the top-down analysis method.Secondly,establish the system of key indicators of safety performance of PTN based on equipment layer,network layer,business layer and network management layer,and design the PTN communication system security architecture,which is "three security plane,the four security layer and the five security dimension".Finally,using AHP and fuzzy comprehensive evaluation method,combining the qualitative and quantitative evaluation,this paper evaluate the safety of PTN communication system for power application and select the ZTE PTN communication system and HUAWEI PTN communication system in the national network of Hebei electric power for the safety evaluation,verifying the rationality of the PTN safety evaluation index system.This paper constructs the evaluation system of the key indicators of the power PTN safety performance,which is used to evaluate the safety and feasibility of the application of PTN technology in power grid.At the same time,it provides a theoretical basis for the large-scale promotion and application of PTN technology in power grid.
