Energy Consumption Analysis and Verification of Permanent Magnet Direct Drive Metro Trains
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 5
Abstract
Objective The permanent magnet direct drive technology for metro trains, as a novel traction solution, offers certain advantages in energy saving and noise reduction. Thus, it is aimed to specifically investigate its energy-saving effect. Method Theoretical analysis is conducted to explore the advantages of permanent magnet direct drive metro trains over (hereafter abbreviated as conventional) metro trains in terms of energy consumption. Taking the example of the permanent magnet direct drive trains on Line 1 in Xuzhou city, the design scheme of permanent magnet direct drive metro trains is introduced. Considering the actual route conditions, the energy-saving effect of permanent magnet direct drive metro train relative to conventional metro trains is calculated. Finally, the advantages are verified through experiments. Result & Conclusion The permanent magnet direct drive traction system has a higher advantage in energy saving compared to conventional system.
