Based on the Safe Operation of Electrified Railway Traction Power Supply Research of Harmonic Suppression

Abstract:

According to the base function and harmonic wave voltage separate effect of different mathematical model is set up the extension of the hybrid filter respectively. In the MATLAB environment, the paper analyzes the active filter effectively restrain system to the power grid impedance of the series-parallel resonant characteristics of passive power filter device and tolerance sensitivity of quality factors. Conclusion: capacitor tolerance have bigger influence on the quality factor. And through the programming into hybrid filter above build simulation module, the simulation is to get ideal effect of reactive power compensation and harmonic suppression.
