High speed EMU operates between two parking stations.If the interval average speed calculated according to the running time specified in the timetable is the target speed,it must be delayed.If the train operates according to the designed speed limit of the track,it must arrive at the station earlier than the timetable.Between these two speeds,there is an"ideal target speed",which can ensure the arrival of high-speed EMU on time.By establishing and analyzing the energy consumption model of high-speed EMU,this paper considers that the energy consumption equation of high-speed EMU is the third power of speed.Therefore,the"ideal target speed"found by iterative algorithm can meet the two requirements of punctual arrival and minimum energy consumption of high-speed EMU at the same time.Through simulation comparison,it is proved that the energy-saving algorithm can fully meet these two requirements.
