factors proposed by IEC61000-3-6 to electrified railway load.
It is proved that the coincidence factors of traction loads are
more and more stable with number of traction substation
increasing based on statistic and calculation of a lot of
measurement data of electrified railway. Factual coincidence
factors of traction loads are put forward and the influence of
coincidence factors on distribution of harmonic emission limits
to users is illustrated in this paper. When individual user's
harmonic emission level is evaluated, sufficient consideration
of coincidence factors is necessary especially for peculiar user,
such as electrified railway. It will make power quality standard
involved in harmonic more rational.
