Feasibility analysis for conceptual design and application of hybrid type traction system for improved acceleration and deceleration performance of urban and metropolitan railway

초록

This paper is a conceptual design and application feasibility analysis of a hybrid traction system forimprovement of acceleration and deceleration performance of urban and metropolitan railway. Due to economic developmentin the metropolitan area, the commuting time and scheduled speed have decreased. This has greatly reducedspeed competitiveness and significantly reduced the modal share rate. To solve these problems, a study was conductedto improve the performance of acceleration and deceleration as a means of express service of urban and metropolitanrailway. A conceptual design of a hybrid type traction motor, which can be applied to both the motor car and trailer carfor enhanced acceleration and deceleration, was carried out. A permanent magnet synchronous motor with better efficiencyand output density than those of an induction motor is applied to the motor car and a linear induction motor issuggested for application to the trailer car. In conclusion, the proposed hybrid type traction motor, which converts allcars to motor cars, improve the acceleration and deceleration performance.
