磁暴数据的多尺度分析
Multi-scale analysis of magnetic storm data
摘要
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.关键词
