Question
Download Solution PDFIn an electric traction, the specific energy consumption is measured in ______.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- The energy input to the traction motors is called specific the energy consumption of the train since it is the energy consumed for propelling the train.
- The total energy drawn from the distribution system will be greater than this by the quantity required for lighting, heating, control, and braking.
The specific energy consumption can be expressed in watt-hours per tonne-km.
\(specific\;energy\;consumption = \frac{{Energy\;consmption\;of\;train\;in\;watt - hour\;}}{{Weight\;of\;train\;in\;tonne \times distance\;of\;run\;in\;km}}\)
Typical values of specific energy consumption are:
- 50 – 75 watt-hours per tonne-km for suburban services
- 20 – 30 watt-hours per tonne-km for mainline service
