The Analysis And Comparison Of Several Domestic Typical Traction Drive System

With the economy development of our country,The people’s require of travel and the train’s speed become higher and higher.Our country use the way of introduce,digestion and absorption to speed up the development of high-speed railway,with depth analysis and comparison of several domestic typical traction drive system is condusive to accelerat the pace of localization of high-speed railway.The paper firstly introduce the development overview of domestic and aboard electric traction AC drive locomotive,then introduce the part of traction drive system.We mainly research on the working principle and control method of pulse rectifier,intermediate DC circuit,traction inverter and traction motor.Next I design the method of compare the traction drive system,the paper mainly use the method of compare the structure and technical parameters of traction drive system;compare the control method and technical parameters of converter and traction motor,we can recognize that the size of the current through IGBT relat to the loss of the converter;and propose the method of evaluation traction performance.With the information and data of HXD eletric locomotive and CRH EMU traction drive system during the research process,use the compare method which I have designed to follow by analysis to evaluate the technology performance of the various models.summarize some problems in the traction drive system,discuss the optimization of the traction drive system of HXD electric locomotive and CRH EMU.Finally have a comprehensive analysis,propose that which kind of model’s traction drive system have the best performance,highest efficiency and highest stability.The major innovation of this paper is that propose a new method on evaluate the different traction drive system combine with practical.And propose that analysis traction characteristics curve to evaluate the traction performance.The conclusion have a certain guiding function of the evaluation of the traction drive system.
