Optimum Power Conditioning and Motor Combination for Locomotive Traction

摘要

This is the interim report describing the results of the research on Phase I, the first year, of this contract. The object of the research is to study alternate power conditioning-motor combinations for single axle locomotive traction drives applicable to both freight and passenger use. Candidate systems are defined and analyzed on the basis of costs, reliability, size, efficiency and performance. The three preferred candidate systems are a McMurray commutated voltage source inverter, an auto-sequentially commutated current source inverter, each supplying a variable frequency squirrel cage induction motor. The GTO inverter-induction motor system is recommended as the most compact system with at least equal or better reliability, performance, efficiency and cost than the other two candidate systems.
