Problems solved by technology

However, the security loopholes in the power secondary system are vulnerable to attacks by hackers. Once any third party invades the substation system and intercepts, changes, or forges the real-time data of the substation, it may cause the relay protection system to be paralyzed and cause large-scale power failure

Abstract

The invention discloses a data security protection method and system. The data security protection method is applied to data security protection of a third-generation intelligent substation auxiliary monitoring system, and specifically comprises the following steps: obtaining useful information in master station system information; and based on the obtained useful information, matching different encryption algorithms according to the importance degree to realize hierarchical encryption of the information. The data acquired by each sub-detection system in the substation auxiliary monitoring system is layered according to the importance degree, and different data encryption methods and different backup methods are adopted for the data of different layers, so that the workload of a computer is reduced, the storage space is saved, and the data transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of application of electric power system intelligent substations, and in particular relates to a data security protection method and system. Background technique [0002] The power grid is an important infrastructure of the country, and the security of the power grid is related to the operation of the entire country, and it is a very basic security protection object of the country. [0003] At present, the substation, as an important dispatching object and an important monitoring object of the dispatching center, has gradually realized the intelligent transformation, and its auxiliary system has become an important tool of the substation. There is a large amount of information and data transmission between the main station of the substation and other systems. Whether the information and data are transmitted safely affects whether the substation can operate normally. The security of substation information dat...
