Abstract:

为解决低频振荡分析中广域量测系统存在量测噪声影响和应用希尔伯特黄变换(Hilbert-Huang transform,HHT)进行模态辨识中的模态混叠和伪分量问题,提出基于Stein的无偏似然估计(Stein unbiased risk estimate,SURE)小波阈值消噪和改进的补充集合经验模态分解希尔伯特黄变换(modified complementary ensemble empirical mode decomposition and Hilbert-Huang transform, MCEEMD-HHT)的低频振荡分析方法。首先,对含较强噪声的电网量测低频振荡信号,采用SURE小...
