Abstract: As the problem of high energy consumption of urban rail transit becomes increasingly prominent, it is urgent to test the energy consumption of trains and analyze the test data, so as to put forward more reference suggestions for the energy-saving operation of trains. According to the energy flow law of urban rail transit trains, a set of train energy consumption and mileage test equipment that meets the requirements of EN50463 standard is developed. Combined with a variety of sensors, the device can measure the electric energy consumed by the entire train, real-time running speed and mileage, and analyze the test data. Taking the tram test case in Delingha as the background, the energy flow law of urban rail transit, the train test device and the test data analysis method are introduced in detail.
