| Abstract: | Magnetic storm may have effects on the safe operation of technical system, such as power grids, oil and gas pipelines and so on, so the analysis of time-frequency characteristics of magnetic storm have great significance for technology systems. In the paper, decomposing magnetic storm data of Zhaoqing into high or low frequency elements with multi-scale wavelet transform, we study time-domain characteristics of magnetic storm component and obtain some valuable conclusions. |
