基于電力應用的PTN安全測試及綜合評價
[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.
