Subway train delay adjustment method considering passenger flow influence and regenerative braking energy utilization

Abstract

The invention discloses a subway train delay adjustment method considering passenger flow influence and regenerative braking energy utilization, and the method comprises the steps: building a passenger flow prediction model based on an LSTM (Long Short Term Memory) in consideration of the constraint of a passenger flow factor on a dwell time adjustment upper limit after a train is delayed; in consideration of absorption and utilization of regenerative braking energy in the delay train adjustment process, a direct-current traction network energy consumption calculation model is established; a station dwell time model is established by simulating the getting-on and getting-off process of passengers; then, a subway train delay adjustment model is established in combination with the submodels, the minimum energy consumption variable quantity of a transformer substation in the adjustment process serves as an optimization target, and a solving process is designed for the model through a particle swarm optimization algorithm CDPSO based on center-discrete learning; and finally, performing simulation verification by using actual subway line data. The method is scientific, reliable and efficient, provides data and theoretical support for subway train delay adjustment, and has high use value and application prospect.

Description

technical field [0001] The invention belongs to the technical field of signal control in a subway operation system, and in particular relates to a subway train delay adjustment method considering the influence of passenger flow and the utilization of regenerative braking energy. Background technique [0002] With the rapid development of the subway operation system, its scale is constantly expanding, and the density of the subway network is also expanding. It has brought a lot of pressure to the operation department of the subway, and a small mistake may lead to the delay of the train. If the train is delayed and not adjusted in time, it will have a great impact on the subway operating system. Therefore, measures should be taken to adjust the operation of delayed trains so that they can resume on-time operation as soon as possible. [0003] When the delay of the train is relatively light, the ATS system of the subway train can adjust the arrival and departure time of the d...
