Key technologies of data security protection system for power grid

Abstract

Abstract The extensive application of a large number of intelligent terminals and advanced communication technologies in the smart grid has greatly increased the pathways in which various sensitive business data are destroyed and leaked out. Existing data security protection methods relying mainly on encryption and access control cannot meet the requirements of data security protection in all aspects of the smart grid. Firstly, this paper presents data security protection system management platform architecture for smart grid from the aspects of data classification, data label management, policy management and authority management. On this basis, the data protection system for smart grid introduces the functional modules and flowcharts of the data security protection system for terminals and networks in detail. In the future, the data security protection system can be applied in generation, transmission, substation, power distribution and electricity consumption of power system.
