WebAug 9, 2024 · The background harmonic source is the system harmonic source, and its degree of fluctuation is larger than any other harmonic source at the PCC. Thus, it can be seen from Figure 5, the data with small system harmonic source fluctuations are selected by the CCA, and the data with large system harmonic fluctuations are removed. WebA harmonic impedance estimation method is proposed in this paper, which takes the Gaussian mixture regression (GMR) as the main idea, and is dedicated to calculating the harmonic impedance when the load changes or the background harmonic changes in the traction power supply system.
