- W2376714669 abstract "Research purposes:The braking control system is one of the key technologies for guaranteeing the running safety of high-speed EMU and an important part of the driving system of EMU.The regenerating braking is used for the high-speed EMU along with the electric air braking.Among the various braking methods,only can regenerative braking feedback the energy to the catenary.Thus it has become the first choice for the braking mode of AC traction EUM.How to realize the smooth changing-over among the different control ways for the traction,braking,constant-speed and coasting and how to control the unity power factor of feedback are the key technologies of regenerating braking control system.In this paper,taking the CRH2-EMU as the study object,the research is done on the key regenerating braking technologies of the EMU for providing the references to the digesting,absorbing and re-innovation of the key traction current-converting technology for the high-speed EUM. Research conclusions:(1) A constant speed controller based on double-hysteretic band adjustment is designed in order that the EMU can stably run at any speed ranging from 0 to 250km/h.(2) The simulation system can realize the energy feedback and control of the unity power factor when the EMU is in the regenerating braking state,and the system can give the regenerative braking order again according to the characteristic curve to meet the running demand of high-speed EMU." @default.
