Study On Design Of The Hybrid Traction Drive System For LRV

Low-carbon transport is currently the world are conducting research and development fields rail vehicles a subject, in this area, the use of hybrid schemes rail vehicle driver, which is an important topic. The present study is mainly internal combustion+cell hybrid combination of hybrid city buses have started practical applications, but the hybrid railcars few studies, there is no practical application of the project, through the analysis research, in the domestic application of more70%low-floor light rail vehicles, the use of super-capacitors and pantograph hybrid-powered solutions for rail transport of the hybrid vehicle research is very necessary and of great significance.This paper studies the super capacitor and by the power supply rail hybrid vehicle traction drive system, the use of super capacitor energy storage devices powered and hybrid-powered mode by power grid solutions, designing a source of energy using two light rail vehicle traction drive systems. The main contents are as follows:In the analysis of the situation at home and abroad as well as several hybrid vehicles currently available technology solutions, combining modern streetcar Shenyang Hunnan project’s technical requirements, select the pantograph super capacitor hybrid power technology solutions for the system technology solutions.Through the project in the practical application of the target vehicle, for computing the energy of the super capacitor, with the vehicle operation of the simulation calculation for the number of super-capacitors and use design.The actual system design and construction, working conditions through the use of simulation and practical application of the pilot testing, to achieve the technical requirements of the original project, the completion of the pantograph ultra-capacitors and hybrid-powered traction drive practical application. Paper gives the final results and analyzed data.Experimental results show that the system has no subject can drive the vehicle through the grid area and perform multiple lockout condition Kai ability, and can be achieved within a subject area of the vehicle power green energy, reduce system energy consumption to improve vehicle energy consumption indicators there are a great help.
