Effect of harmonic distortion on motors
WebHarmonic propagation is simulated in a detailed distribution network model to analyze how circuit topology varies harmonics effects. Due to the interaction of different harmonic sources, the sensitivity analysis is conducted to show the impact of each harmonic source magnitude and angle on the overall distribution network total harmonic distortion. WebThe increasing use of nonlinear loads in the power grid introduces some unwanted effects, such as harmonic and interharmonic contamination. Since the existence of spectral contamination causes waveform distortion that may be harmful to the loads that are connected to the grid, it is important to identify the frequency components that are …
