Research on Main Circuit Topology and Traction Performance of Hybrid Diesel-electric Locomotive
The hybrid diesel-electric locomotive can effectively solve the problem of cross-line connection between electrified and non-electrified lines.Using the hybrid diesel-electric locomotive can optimize the structure of railway network,improve transportation efficiency and save operation cost.In the paper,different kinds of main circuit topology are compared from traction system and auxiliary system respectively.Traction characteristics in mode of diesel are proposed based on the main circuit topology structure.Traction performance is calculated through simulation analysis,and the traction performance of existing freight lines is simulated and verified,which provides theoretical reference for the development of the hybrid diesel-electric locomotive in China.
