| Summary: | The energy-saving operation control curves, which contained working conditions such as maximum traction & braking stage, minimum traction & braking stage, rest stages and coasting, were deduced from the constructed mathematical model of operating energy consumption according to running speed, traction & braking characteristic, railway line features. The division sequence was derived from running section discretization, and the velocity turning sequence was composed of speed transition points on the railway section; then, the optimal control strategy of energy economizing operation, which combined some working modes such as maximum traction & braking, rest stages and coasting mode, was obtained according to optimum speed turning sequence; the velocity, energy consumption and mileage relationship curves were deduced by simulation analysis of operating conditions such as minimum running time, driver manipulation and energy saving mode based on actual track data and EMUs parameters. The effectiveness of energysaving operation control strategy was verified by analysis & comparison between simulation results and practical test data. |
