基于坡道的城际铁路节能操纵策略

Energy Saving Control Strategy of Intercity Railway Based on Ramp

提出一种在线计算列车运行工况转换点的节能操纵策略,根据城际列车性能、线路数据和阻力特征,计算坡道终点的命令速度,预测列车在坡道终点的运行速度,实时判断列车是否可以进入节能工况。基于真实列车牵引能耗功率曲线进行建模,以此验证提出的策略有效性,并绘制杭海城际铁路区间运行时间与牵引能耗的关系曲线。

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 eff ectiveness 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.
