HHT_power-system_power-quality_disturbances-detect
- 优秀论文及配套源码。Hilbert-Huang变换(HHT)是一种新的非平稳信号处理技术,该方法由经验模态 分解(EMD)与Hilbert谱分析两部分组成。任意的非平稳信号首先经过EMD方法处理后被分解为一系列具有不同特征尺度的数据序列,每一个序列称为一个固有模态函数(IMF),然后对每个IMF分量进行Hilbert谱分析得到相应分量的Hilbert谱,汇总所有Hilbert谱就得到了原信号的谱图。该方法从本质上讲是对非平稳信号进行平稳化处理,将信号中真实存在的不同尺度波动或趋势逐级分解出来,最
