Efficiency of using electric power for traction of ED4M electric multiple units
Keyword(s):
The paper presents results of 6-car and 8-car ED4M electric multiple unit rides and assessments of various factors influence on power consumption. In particular, the paper considers modes of starting and braking on example of speed-time curves and traction motor current-time curves at different starting accelerations. A detailed analysis showed at unaltered running time due to higher starting acceleration and lower starting braking speed the power consumption decreases and at lower starting acceleration and higher starting braking speed it increases. Besides, the paper considers an influence of such factors as density of population, train length, weather conditions and divergence of characteristics of motor-wheel units of motor cars.
