低碳环保、节能减排是铁路未来的发展趋势,为减少城市轨道列车的能耗,将列车处理为单质点模型,近似地认为城市轨道列车在两站间只经历牵引、惰行和制动3个阶段,在此基础上建立具有代表性的城市轨道交通系统单列车能耗优化的非线性规划模型,利用序列二次规划法(SQP)优化求解,并给出算例验证其可行性。
Low-carbon environmental protection and energy conservation and emission reduction are the future development trends of the railway. To reduce the energy consumption of urban rail trains, the train is treated as a single-mass point model. It is assumed that urban rail trains only experience traction, coasting and braking 3 between the two stations On this basis, a typical non-linear programming model of single train energy consumption optimization for urban rail transit system is established. The SQP (Sequential Quadratic Programming) method is used to optimize the nonlinear programming model. An example is given to verify its feasibility.
