城市轨道交通列车节能控制策略研究

Energy saving control strategy of urban rail transit train

以广州地铁信号系统所控制的列车为例,根据城轨列车运行过程中的受力情况构建单列车的运动方程,依据单列车的运动方程构造哈密尔顿函数、共轭函数、互补松弛函数,研究了列车运行过程的数学模型和模型成立的条件。由此得出单列车运行过程中的最节能控制策略。针对最快速度列车运行控制策略和最节能列车运行控制策略,分别在列车运行仿真环境和广州7号线进行了对比实验,结果表明,最节能列车控制策略能够减少能量消耗14.8%,同时,显著提高列车运行平稳性。

Taking the train controlled by the Guangzhou subway signal system as an example,the motion equation of the single train was constructed according to the force condition in the running process of the urban rail transit train.Based on the motion equation of the single train,the Hamilton function,the conjugate function and the complementary relaxation function were constructed.The mathematical model of the train operation process and the conditions for the establishment of the model were studied.The most energy saving control strategy in single train operation was obtained.Facing with the fastest speed train operation control strategy and the train operation control strategy of the most energy saving,the comparison experiments were carried out in the simulation environment of train operation and the Guangzhou No.7 line respectively.The results show that the most energy saving train control strategy can reduce the energy consumption by 14.8%,significantly improve the running stability of the train.
