Emission Limits to Harmonics of Electrified Railway

  • The impact of harmonic impedance on the relationship between harmonic voltage and harmonic current emission limits was discussed based on a comparison between IEC 61000-3-6 and GB/T 14549-93.There exist differences between traction loads and general loads in determination of the agreed power of the consumer and the total available power,harmonic summation exponent and coincidence factors of multiple harmonic sources.Therefore the distributing method of harmonic emission limits for traction loads is different from that for general loads,and application of the 3-stage method in IEC 61000-3-6 is recommended in the cases of traction loads.An example of an electrified railway in China was presented to show the application of the 3-stage method to evaluate the harmonic voltage emission levels of traction loads.
