Abstract

The invention discloses a power communication system and method and relates to the communication technical field. The power communication system and method solve the problem of high cost in application of a communication system to a power secondary system in the prior art. The power communication system comprises a plurality of safety working areas, transverse partition devices and longitudinal transmission devices. Each safety working area comprises a plurality of business systems, the transverse partition devices are arranged among the safety working areas of different safety grades and used for transversely connecting the safety working areas of different safety grades, the longitudinal transmission devices are arranged in the safety working areas and used for establishing a virtual private network (VPN), and the business systems in the safety working areas are longitudinally connected through the VPN. The power communication system and method are mainly applied to the process of the communication among the safety working areas and in the safety working areas in the power secondary system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an electric power communication system and method. Background technique [0002] The power system includes a power primary system and a power secondary system. The power primary system mainly refers to the power supply system, and the power secondary system mainly provides functions such as detection and protection for the power primary system. In order to enable the power secondary system to distribute electric energy safely, economically and rationally, to ensure power quality indicators, and to deal with and prevent system accidents in a timely manner, it is necessary to establish a corresponding communication system to centrally manage and unify the power secondary system. scheduling. [0003] However, due to the different security levels of different business systems in the power secondary system, in the prior art, in order to improve the security of business ...
