高速列车运行图节能优化研究现状及展望OA北大核心

To clarify the research context of energy-saving optimization for high speed train working diagrams,this paper primarily summarized relevant research in China and abroad focusing on energy-saving operation modes,construction of energy-saving working diagram models,and algorithm designs for high speed trains.The results indicate that the energy-saving operation of high speed trains is characterized by various coexisting energy-saving methods and the intersection of different disciplines.The research content extends from optimizing train control strategies in a single section to optimizing train working diagrams.Model constraints transition from considering simple speed limits and time limits to considering multiple factors such as train safety time intervals,complex line conditions,and electric phase division areas.The algorithm concept evolves from using the basic Pontryagin principle to employing various heuristic algorithms for facilitating rapid solutions,along with using accurate algorithms for preprocessing to enhance solution accuracy.Future studies can delve into the influence of driving strategies and operation plans of high speed trains on energy consumption under complex operation conditions,as well as energy storage devices for regenerative braking energy of high speed trains.
