Research on Communication Security Performance of Distribution Network

Abstract

With the rapid development of power distribution network, the level of informatization and intelligence of power distribution equipment has been continuously improved. More and more smart devices are connected to the power grid through the distribution communication network. The distribution communication network has a large coverage, many access devices and scattered deployment, which puts forward higher requirements for the security of the distribution communication network. Starting from the distribution communication network architecture and distribution communication network business structure, this paper analyzes the security risks faced by the distribution communication network and the impact of various security risks. Secondly, from the perspective of power line carrier communication security, a relay eavesdropping channel model is established, and based on this, the influence of artificial noise on the security performance of power line carrier communication is analyzed.
