Reasonable train control can reduce energy consumption during train operation to a large extent.In order to effectively reduce the energy consumption of high-speed train operation,we start from the research on train operation mode.Firstly,the train traction calculation model and train operation energy consumption calculation model are established.Then,optimization performance of artificial bee colony algorithm(ABC algorithm)is compared with that of the particle swarm optimization algorithm(PSO algorithm),which proves that the ABC algorithm is better than the PSO algorithm.Therefore the method of combining ABC algorithm with train control sequence is proposed to optimize and determine the optimal transition point position and the speed of high-speed train control under the condition that the speed,time,range and other constrains in operation are satisfied.Finally,through the MATLAB simulation of the selected line,the ABC algorithm is very effective in reducing energy consumption of the train.The research shows that the results obtained by ABC algorithm satisfies the basic control strategy of optimal operation mode and achieve good optimization effect,which can better solve the problem of train energy-saving operation optimization.
