Design of electric traction system for high speed railway
Abstract As Beijing, Tianjin, Wuhan Guangzhou, Beijing Shanghai high speed passenger dedicated line have been put into operation, the rapid development and expansion of the railway network in China. High speed railway with the in running speed, transmission capacity and in the transmission of the most important safety performance, now most concerned about energy consumption cash outstanding advantage to become the focus of China's railway development and lead the direction of China's railway, high-speed railway development is inseparable from the progress of traction power supply system design, high-speed railway EMU traction part is the part of the core is electric traction AC drive and control technology, and has important theoretical significance and practical value for the research.
First of all, this paper introduces the basic structure parameters of No. harmony crh380a, mainly to determine the traction motor and traction transformer of the type and rated parameters, and in the car as an example that electric traction system structure part and play a role; secondly, the AC-DC-AC type high speed EMU of AC drive technology research. AC drive system is mainly composed of transient current control of four quadrant pulse converter, intermediate DC link, space voltage vector control inverter and traction motor, traction motor rotor field oriented vector control technology. Finally, according to the selected train traction motor, on-board traction transformer The parameters of the grid and the running characteristic of the train traction are calculated, and the technical parameters of the AC drive circuit are calculated, and the circuit diagram of the traction converter system is designed.
There are 20 figures, 7 tables and 24 references in this paper.
