Abstract


Electric Railway locomotive along the railway mobile electricity generated harmonic grid hazards broader than other harmonic source serious traction power supply system harmonic accurate detection of Electric Railway has important practical significance . Issues the background harmonic harmonic effects directly related to the division of responsibilities , emission levels to provide the basis for a clear harmonic pollution responsible for analysis of background harmonics . Summarize the existing electricity harmonic detection method based on Adaline neural network optimized harmonic analysis method , traction substation primary current Harmonic Detection of Electric Railway Traction simulation system , the results show that this method higher harmonic detection accuracy . Compare the various harmonic emission level estimation method based on the harmonic emission level estimation method based on robust regression method , a numerical example is the common connection point at the background harmonic analysis , illustrated the feasibility of the method .
