Abstract

The invention relates to a power grid fault diagnosis method and apparatus, and a storage medium. The method comprises the steps of obtaining alarm information of a power grid; acquiring a wavelet packet time-frequency spectrum grey-scale map of the alarm information; calling a preset fault diagnosis model to perform feature recognition on the wavelet packet time-frequency spectrum grey-scale map to obtain a power grid fault type; wherein the fault diagnosis model is a CNN-SVM fusion model; pushing the power grid fault type to a maintenance terminal for visual display; according to the invention, the technical problems that the traditional power grid fault diagnosis efficiency is low and the power grid fault cannot be processed in time can be solved.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a power grid fault diagnosis method and device, and a storage medium. Background technique [0002] With the rapid expansion of the grid scale, the load of the grid continues to increase, and its safety, reliability and ability to resist external interference are reduced. The power grid may fail at any time. If it is not restored in time, it will easily cause cascading failures and lead to large-scale power outages. [0003] At present, in order to monitor the working condition of the power grid, a large number of sensor monitoring devices are used to collect the alarm information of the power grid. After the power distribution room receives the alarm information, the traditional method needs to manually judge the information in the alarm information based on operating experience, which requires high skills and takes 5 minutes. The whole process takes a long time, resulting...
