【摘要】：PTN技术是IP/MPLS、以太网和传送网三种技术相结合的产物,作为未来电力通信网中一种很好的传送和承载技术,顺应了电网业务多样化、IP化、智能化、宽带化的发展趋势。但是PTN综合承载电力系统各安全分区业务的软隔离效果,设备系统安全性,抗网络攻击能力,网管安全性,关键性能指标是否满足电网业务需求等相关问题尚无定论,因此有必要开展基于电力应用的PTN安全测试及综合评价技术研究。本文针对以上问题,首先,调研了PTN在电网应用与承载现状,分析了基于电力应用的PTN安全需求,构建了电力PTN安全性能评价关键指标体系的总体目标以及子目标;其次,构建了以设备层、网络层、业务层、网管层为基础的PTN安全性能关键指标体系,设计了“三安全平面、四安全层、五安全维度”的PTN通信系统安全体系结构;最后,采用层次分析和模糊综合评价方法,结合定性与定量评价优势,对电力应用的PTN通信系统进行安全性综合评价,并选取国网河北行唐县电力的中兴和华为PTN通信系统进行测试以及安全性评价,验证了本文构建的PTN安全性关键指标体系及评价方案的合理性。本文构建的电力PTN安全性能关键指标评价体系,用于评价PTN技术在电网应用的安全性与可行性。同时,也为PTN技术在电网的大规模推广与应用提供了理论依据。
[Abstract]:PTN technology is the product of the combination of IP/MPLS, Ethernet and transmission network. As a good transmission and carrying technology in the future power communication network, it conforms to the development trend of the diversification, IP, intelligence and broadband of the power grid. But PTN combines the soft isolation effect of the security partition services of the power system and the equipment system security It is necessary to carry out the research of PTN security testing and comprehensive evaluation technology based on power application. This paper, first of all, has studied the status of PTN application and carrying capacity in power grid, and analyzed the power based on electricity. The PTN security requirement of force applied, the overall target and sub target of the key index system of the power PTN security performance evaluation are constructed. Secondly, the key index system of PTN security performance based on the equipment layer, network layer, business layer and network management layer is constructed, and the PTN communication system of "three security flat surface, four security layer and five security dimension" is designed. In the end, using the analytic hierarchy process and fuzzy comprehensive evaluation method, combining the qualitative and quantitative evaluation advantages, the PTN communication system of electric power application is evaluated comprehensively, and the Hebei Xingtang County Electric Power Zhongxing and HUAWEI PTN communication system is tested and the security evaluation is used to verify the PTN security set up in this paper. The key index system and evaluation scheme are reasonable. The key index evaluation system of the power PTN safety performance is constructed in this paper, which is used to evaluate the security and feasibility of PTN technology in the application of power grid. Meanwhile, it also provides a theoretical basis for the large-scale popularization and application of PTN technology in the power grid.
