Analysis And Application Of Smart Grid Information Security Technology

The construction of smart grid cannot leave the information construction, which determines the intelligence level and degree of the smart grid. In the process of current information construction of smart grid, most researches and practice for informatization focused on the realization and digging of new features, while they didn’t pay enough attention to the security problems of smart grid under the background of informationization. As one of the important support of the Internet age, the smart grid has brought great changes to people’s work and way of life, but the openness and inclusiveness of the smart grid has also posed challenges to the smart grid information security. Aiming at this problem, this thesis studies the information security technology of smart grid and its applications combining with the case of informatization construction of smart grid.This paper firstly formulates the current research and application of the information security technology of smart grid. On this basis, the characteristics of our country’s smart grid are analyzed, on the basis of which, the significance of information security to the smart grid and the present situation of information security construction of smart grid are discussed. To make the overall deployment to the smart grid information security, the status quo must be first analyzed. In this paper, based on the research thinking of coming from the instance and last returning to the instance, I take W power supply company for example, and then the current problems existing in the smart grid information security are concluded. And targeted protection strategies are worked out based on the analysis. On the protection strategy, this paper will take the "double double machine, points to distinguish the domain, level of protection, multi-layered defense" as the overall strategy for information security protection. At the same time, to strengthen network border security, combing information security level, the paper makes domain division for the information of internal and external network application system security, each security domain according to the boundary, network, host, and application of the four levels of the implementation of safety protection of the environment. Finally, to translate all the safety protective measures to W power supply company information security protection, so as to improve the company’s information security level.Through comprehensive study on the application of the smart grid information security, this paper analyzes the key technology of the smart grid security and puts forward the main points of the construction security of smart grid. Based on the access authentication system, information encryption, security monitoring platform and so on child protection system,it puts forward some ideas of the construction of information security protection system. Also the paper provides the certain reference value for the future construction of the information security of smart grid,.
