Train fast and energy-saving operation control method without idling condition

Abstract

The invention relates to a train fast and energy-saving operation control method without idling condition. The method includes Step S1: canceling the idle condition of the train, and setting the target behavior curve of the fast running of the train with the shortest time as the optimization target, and with the station spacing, the specific line condition and the train performance as the constraints; Step S2: in the actual operation, the high-speed train uses the fast-running target behavior curve as a reference to adjust the train behavior, and uses the electric energy storage device to recover, store, manage, and reuse the regenerative electric energy generated by the braking during the start of the train to the station-stopping period. Compared with the prior art, compared with the situation that the current high-speed train has idle working conditions in the running process, the maximum running speed of the train can be slightly reduced on the premise that the rapidity is guaranteed to be improved, and the energy consumption of the train operation is further reduced.

Description

technical field [0001] The invention relates to a train control method, in particular to a fast and energy-saving operation control method of a high-speed train without coasting conditions. Background technique [0002] In the field of rail transit, research on energy-saving operation of trains has accumulated a large number of achievements, mainly reflected in the optimization of energy consumption in the microscopic behavior of trains, and the utilization of regenerative electric energy based on train schedules in the macroscopic perspective. [0003] The optimization of energy consumption for the microscopic behavior of trains is basically to achieve energy-saving operation by prolonging the train’s coasting time as much as possible, because during the coasting period, the train completely relies on the resistance generated by the wheel-rail interaction, the additional resistance of the ramp or curve, and Air resistance is used to reduce the running speed, and no traction...

Problems solved by technology

[0005] (1) The imbalance of population distribution and economic development leads to the imbalance of time and space distribution, flow direction and flow of transportation tasks. Therefore, it is extremely difficult to compile an "abnormally perfect" timetable for the recovery and direct use of regenerative electric energy. can't do it

[0006] (2) The utilization of regenerative electric energy based on the train timetable is not based on the premise of canceling the train's idle behavior, and the existence of the idle phase affects the speediness of the train operation, thus affecting the establishment of the train timetable. The two are mutually causal. In terms of energy saving and quickness, it will fall into the trap of circular paradox
