recently, the issue of high-speed rail energy consumption has attracted attention. there is an online rumor that "my country's high-speed rail consumes 10,000 kilowatt-hours of electricity per kilometer". is this true? in response, the china railway corporation said:this statement is actually a misunderstanding and confusion of concepts.

at the research institute of the china academy of railway sciences, engineer huang jin showed reporters a set of data: an energy consumption test was conducted on four main emu models with eight carriages on the beijing-shanghai high-speed ​​railway. all four models traveled 2,636 kilometers round trip at a speed of 350 kilometers per hour. the average power consumption per kilometer was 21.6 degrees, 23.5 degrees, 19.5 degrees and 21.1 degrees respectively.the statement circulating online that "one kilometer consumes 10,000 kwh of electricity" confuses the concepts of unit time and unit mileage and is inconsistent with the facts.

huang jin, deputy chief engineer of the locomotive and rolling stock research institute of the china academy of railway sciences:generally, the unit of measurement of 10,000 kwh is probably more about wheel power. the wheel power of fuxing is mostly in the order of 9,700 kilowatts to 10,000 kilowatts. if it runs for one hour at a power of more than 9,000 kilowatts, it is more than 9,000 kwh, but the train runs for one hour, and the distance it runs may be more than 300 kilometers. there is a misunderstanding in this statement.

experts told reporters that the industry generally uses two ways of expressing the energy consumption of high-speed rail. one is kilowatt-hour per person per 100 kilometers, which represents the energy consumption of each passenger for a train traveling 100 kilometers; the other unit is kilowatt-hour per train per kilometer, which represents the energy consumption of a high-speed train for one kilometer. my country's high-speed trains consume about 21.4 degrees of electricity per kilometer, which is comparable to the energy consumption of other high-speed railway trains in the world.

huang jin, deputy chief engineer of the locomotive and rolling stock research institute of the china academy of railway sciences:when we analyze the energy consumption of emus, we first bring its units to the same level and compare them on the same scale. under the same scale, the energy consumption of our emus is basically the same as that of foreign emus. at the level of 350 km/h speed trains, ours is slightly better than theirs.

efficient operation of my country's high-speed rail reduces energy consumption per passenger
