Abstract

The necessity of electric energy quality evaluation, consumed by electric rolling stock (ERS) in traction mode and generated in recuperative braking mode, is not discussed. If this task for the traction mode is solved sufficiently, then for the recuperative braking mode of DC ERS such investigations are unknown. I the paper the quality indices of recuperated electric energy are represented by the voltage deviation, the voltage oscillation, and also the voltage impulse and temporary overvoltage. The numerical evaluation of these indices is done and shown for recuperated (and further inverted) energy , which was generated by electric locomotives VL11M6 in the sections of Prydniprovsk railway. It is determined that the real values of all mentioned indices of quality are step outside the limits of admissible quantity. The quality of inverted electric energy is investigated for the section Volovets – Batiovo of Lviv railway at the moment of electric locomotive VL11M operation. Inverting was done on railway substation Volovets. It is established that the voltage after inverting almost sinusoidal (although has non-paired harmonics) and current which is unclean considerably, integral indicator THDI in 3,6 times increases the accepted value, that is 5 %. As to the research results, the conclusion is the recuperated electric energy is the energy of low quality.
