Simulation Results on the Currents Harmonics Mitigation on the Railway Station Line Feed using a Data Acquisition System

摘要

With the progress of power electronic devices in electric railway, harmonics in power systems become increasingly of concern. This paper presents a case study on harmonics in a traction power supply system. The study was based on measurements realized in an electrical drive station using a data acquisition system and a computer. It was analyzed the main power quality indicators: the power factor, the reactive power factor, the deforming power factor and the total harmonic distortion of the current and voltage. The paper present also the simulation results of process of electric drive vehicles especially in railway using different passive LC filters using PSCAD-EMTDC simulation program.
