Abstract: This paper deals with the problem of harmonic mitigation solutions in a Romanian traction substation which supplies a railway electric transportation line. The power line measurements were made using an ABB Power+ recorder and analyzer during a whole day. The quantities recorded have been the frequency, the total rms values of the voltage and current, the current and voltage harmonic distortion factors and the first fifteen current and voltage harmonics. The analysis of data shows that the harmonic distortion factor of the voltage is always less than IEEE 519 recommended limit thanks of high power of the transformer comparatively with the power of the load. In order to keep the current distortion within allowed limits, the proposed filter installation must lead to a significant diminution of 3rd and 5th harmonics and a less significant diminution of the superior order harmonics. In this concrete application, the proposed solution for harmonics mitigation is based o!
n passive power filtering. The simulations carried out under Matlab Simulink environment show that the installation of two single tuned filters for third and fifth harmonics plus a high-pass filter for higher order harmonics would reduce harmonics levels and harmonic distortion factor to within acceptable limits even in the most unfavourable situations.
