Abstract

The invention discloses a method and system for monitoring the operation state of power grid embedded terminal equipment, and belongs to the technical field of intelligent power grid safety. The method comprises the following steps: acquiring historical operation data of the power grid embedded terminal equipment in different safety states; according to the collected historical operation data, determining operation characteristics representing the historical operation data of the power grid embedded terminal equipment in preset time; constructing a GRU neural network architecture according tothe operation features, dividing historical operation data into a training set and a test set, and inputting the training set and the test set into the GRU neural network architecture for training toobtain a training model; and acquiring operation data of the to-be-monitored power grid embedded terminal device, testing the operation data by using the training model, and determining an operation state of the to-be-monitored power grid embedded terminal device. According to the method, the accuracy of identifying the operation state of the power grid embedded terminal equipment is higher, and the robustness is higher.

Description

technical field [0001] The present invention relates to the technical field of smart grid security, and more specifically, to a method and system for monitoring the operating status of embedded terminal equipment in a grid. 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, intelli...
