牵引策略对动车组运行能耗的影响
|
摘要
通过理想化假设,分析曲线、坡道、桥梁、隧道对动车组受力的影响,建立动车组牵引能耗仿真计算模型,并根据实际线路运行结果对模型进行验证。在实际线路参数的基础上,通过能耗模型模拟计算研究启动加速阶段、中间运行阶段以及制动阶段的不同牵引策略对动车组的运行时间、能耗的影响,并提出评价动车组牵引能耗的时间-牵引能耗经济性指标,以考察各种牵引策略的节能、节时潜力。研究结果表明:在惰行终点速度为110 km/h时,动车组牵引能耗达到1个能耗局部最低点。
The effect of curve, ramp, bridge and tunnel on the force of CRH was analyzed to establish a calculation model of traction energy consumption of CRH, which was verified by field results. The calculation model was used to study the effect of traction strategy on traction energy consumption and running time of the CRH in different operation stages. In order to evaluate the energy-saving and time-saving potential of different traction strategies, the traction energy consumption time-economy index was put forward. The results show that the traction energy consumption of the CRH is the lowest when the coasting speed is 110 km/h.
