Embodiment Construction

[0029] In order to make the content and effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below.

[0030] The safety monitoring method for power grid embedded terminal equipment based on side channels provided by the present invention includes equipment operation state information collection, data preprocessing, feature extraction, equipment normal operation state model establishment, equipment next operation state prediction, and equipment operation state abnormal detection. By classifying the operating status information of embedded terminal equipment in the power grid, power consumption is selected as the status information when the equipment is running, and through real-time monitoring of the equipment operating status, it is compared with the normal operating status model of the equipment to determine whether the equipment is running abnormally. The equipment operating state model adopts a cyclic neural...

Abstract

The invention discloses a power grid embedded terminal safety monitoring method and system based on a side channel, and belongs to the field of intelligent power grid safety. The method comprises thesteps of equipment operation state information acquisition, data preprocessing, feature extraction, equipment normal operation state model establishment, equipment next operation state prediction andequipment operation state anomaly detection. The operation state information of power grid embedded terminal equipment is classified, the power consumption is selected as state information when the equipment operates, and the operation state of the equipment is monitored in real time and compared with a normal operation state model of the equipment for analysis, so that whether the equipment operates abnormally or not is judged. According to the invention, the operation state of the power grid embedded terminal equipment can be monitored, and the safety performance of the terminal equipment isimproved.

Description

technical field [0001] The invention belongs to the field of smart grid security, and relates to a side channel-based grid embedded terminal security monitoring method and system. Background technique [0002] The power system is closely related to our life. As a platform for electric energy production and transmission, it needs to meet the requirements of reliability, flexibility and economy. With the rapid improvement of power system informatization, the power grid is constantly developing towards a more intelligent direction. As one of the most widely used technologies today, embedded technology has become an indispensable part of power system control and monitoring. It is widely used in all aspects of smart grids, such as PLC, RTU, HMI, etc. in power industrial control systems. It plays a vital role in the development of intelligent power system. While these grid embedded terminal devices make the grid more networked, intelligent, and multi-functional, they also bring ...
