针对电力系统测量数据受噪声污染严重的问题,提出一种快速鲁棒回归平滑降噪方法。首先,通过局部回归平滑过程实现背景噪声降噪;然后,根据全局平滑残差自适应检测离群数据;最后,针对离群数据进行鲁棒回归平滑过程降噪并滑动修复离群数据造成的局部平滑畸变。所述方法实现了全局快速回归平滑、随机脉冲噪声自适应检测、局部平滑畸变快速修复,极大降低了计算复杂性。仿真分析与实测数据分析结果表明,相比传统鲁棒局部回归平滑方法,所提方法不仅保持了良好的背景噪声与高强度随机脉冲噪声降噪能力,还能够有效辨识扰动阶跃突变引起的伪脉冲噪声,提升降噪过程的扰动响应信息保留能力,计算效率优势明显。
For the problem that the measurement data in the power system is seriously polluted by noise
a fast robust regression smoothing denoising method is proposed. First
the background noise is suppressed by the local regression smoothing process. And then the outlier data is detected adaptively according to the global smoothing residual. Finally
the outlier data is denoised by the robust regression smoothing process
and the local smoothing distortions caused by the outlier data are repaired.The proposed method realizes the fast regression smoothing of global data
the adaptive detection of random impulsive noise and the fast repair of local smoothing distortions
which greatly reduces the computational complexity. The simulation analysis and the field measurement data analysis show that
compared with the traditional robust local regression smoothing method
the proposed method not only maintains a good denoising ability against the background noise and the high-intensity random impulsive noise
but also can effectively identify the pseudo impulsive noise caused by the step change due to disturbance. The proposed method improves the preservation ability of the disturbance response information
and it also shows the obvious advantage of computational efficiency.
