This paper presents a modification in the filter banks structure presented in [1][2] for tracking time-varying harmonics distortions. The method uses SSB modulation and does not require the use of notch filters. With this new structure it is possible to track and visualize the time-varying harmonic components of power systems, without frequency spillover caused by time-frequency techniques. This new...
Although it is well known that Fourier analysis is in reality only accurately applicable to steady state waveforms, it is a widely used tool to study and monitor time-varying signals, such as are commonplace in electrical power systems. The disadvantages of Fourier analysis, such as frequency spillover or problems due to sampling (data window) truncation can often be minimized by various windowing...
