EXPERIMENTAL STUDY OF THE ENERGETIC PARAMETERS OF MODERNIZED THYRISTOR LOCOMOTIVES 46-200 SERIES

Georgi Pavlov, Martina Tomcheva, Ilko Tarpov

The low values of the energetic parameters of diode and thyristor electric vehicles operated in railways (over 96%) create conditions for increased consumption of reactive power and distortion of the waveform of the mains current. Consequently, the traction power system and locomotives electrical equipment are loaded with additional reactive current, which leads to an increased traction power consumption. In this article, proportion of energetic tests of modernized thyristor locomotives 46-200 series is shown. An analysis of the obtained results is made and opportunities for improving energy efficiency are discussed. The main purpose is to establish a methodology for a comprehensive study of the energy performance of electric vehicles operated in Railway Transport. This will give the opportunity for carrying out adequate energy analysis and categorization of the electric vehicles on certain parameters characterizing the quality of consumed energy, as well as a proposal for their modernization.
