Abstract


Electric traction with traction, speed, etc. , so modern high-speed rail without exception, the use of electric traction, currently with the power electronics and AC motor speed control technology continues to evolve and mature, and promote an exchange of electric traction traction to become a major way . AC traction drive system uses high-speed EMUs A key feature is the use of regenerative braking technology , regenerative braking technology has become a high-speed EMU braking mode of development is inevitable. Regenerative braking is the traction motor into a generator , the train kinetic energy into electrical energy fed back into the grid through the catenary . The biggest advantage of regenerative braking train braking is achieved , it is also possible to achieve energy saving , reducing the braking system maintenance . Based on the high-speed EMU works , build a high-speed EMU simulation model of traction conditions, regenerative braking and traction conditions working conditions to switch to regenerative braking condition three kinds of the simulation , and the simulation results are analyzed the simulation results show that the high-speed EMU ride simulation model is correct. Through simulation and negative sequence harmonic theory , drawn EMU regenerative braking on the grid negative sequence harmonics . Negative sequence , the main analyzes four different types of traction transformer under EMU regenerative braking effect on the negative sequence to arrive at EMU traction transformer integrated selection method ; harmonic , the first AC-DC electric locomotive -side current harmonics are outlined , and then high-speed EMU rated power traction traction with half rated power grid side current harmonics analysis , as well as regenerative braking and a half rated power rated power regenerative braking into the net side current harmonics analysis, and finally , based on the above analysis, the high-speed EMU traction and regenerative braking harmonic characteristics under comparison , as well as high-speed EMUs with AC-DC electric locomotive harmonic characteristics were compared.
