| The traditional catenary powered tram line has strict requirements on the clearance height,which not only has certain potential safety hazards in the downtown section,but also has a negative impact on the future expansion of the line network.Therefore,the hybrid power supply mode with vehicle energy storage device and catenary has become the current development trend.For this kind of power supply mode,it is very important to reasonably select the on-board energy storage configuration and ground charging scheme based on the actual line conditions and train characteristic parameters.On the premise of meeting the requirements of line operation,this paper puts forward an integrated optimization method of energy storage configuration and ground charging scheme of modern tram,which provides a reference for train selection and ground charging scheme design of modern tram project.The main research work of this paper is as follows: 1.The mechanical model,ATO model,on-board super capacitor model,platform charging device model and train energy consumption calculation model are established to realize the simulation of the whole process of train operation and line operation;2.Based on the non dominated sequencing genetic algorithm with elite strategy(NSGA-Ⅱ),the corresponding optimization evaluation function and on-board energy storage and distribution are designed The integrated optimization algorithm of device and ground charging scheme;3.Based on the analysis of the fault types of the platform charging device,the integrated optimization algorithm of the improved on-board energy storage configuration and ground charging scheme under the fault of the platform charging device is designed;4.Based on the analysis of the working principle of the energy storage platform charging device,the improved on-board energy storage device based on the energy storage platform charging device is designed Can configure and ground charging scheme integrated optimization algorithm;5.Using C + + language,develop the operation simulation and integrated optimization simulation software of tram in QT environment.The actual line data and train parameters of a tram line are used for simulation analysis and calculation.The simulation results show that the integrated optimization method of vehicle energy storage configuration and ground charging scheme proposed in this paper is effective and feasible,which provides data and theoretical support for train selection and line design in engineering projects,and has high use value and application prospect. |
