Study on Fitting Key Parameters of Traction Energy Consumption Model for Urban Rail Trains
In terms of energy saving of urban rail transit,traction energy consumption of trains occupies a large proportion.In order to find a balance between transport capacity optimization and energy saving,traction energy consumption of trains with flexible grouping should be analyzed as a reference for convenience and economy of coordination.A mathematical model of train traction energy consumption is established according to classical mechanics,and an ideal model of traction energy consumption is established for the convenience of research.By analyzing the historical operation data of a Hangzhou Metro line,the key parameters are fitted and the robustness of the relationship curve of fitted key parameters is verified.Based on the actual data of a Hangzhou metro line,the ideal model of traction energy consumption is simulated and verified.The fitting results provide data support for the ideal model of traction energy consumption,and lay a foundation for the deidealization of the ideal model of traction energy consumption.It can be popularized and applied in practical projects,and has good theoretical value and practical significance.
