Abstract: This paper proposes an energy-saving operation strategy for on-line calculation of train operation condition transition point. According to intercity train performance, line data and resistance characteristics, it calculates the target speed at the end of ramp, predicts the train operation speed at the end of ramp, and judges whether the train can save energy in real time. Based on the real train traction energy consumption power curve, the model is built to verify the effectiveness of the strategy proposed in this paper, and the relationship curve between running time and traction energy consumption of Hangzhou-Haining intercity railway is drawn.

Key words: energy saving, ramp, intercity railway
