Energy-saving operation method of train

Abstract

The invention provides an energy-saving manipulation method for a train. The energy-saving manipulation method comprises the steps that the train is pulled to be at a certain speed with the maximum traction force at the starting stage, and then according to information such as the operating speed, line speed limiting, the ramp situation and operating resistance of the train, coasting and constantspeed operating strategies are alternately selected till the train is accurately parked at a target parking point of a station through the maximum braking working condition before pulling in; and on the basis of reading-in of train parameters, line data and the planned operating time, the switching position of a working condition sequence is optimized through a Brute-Force algorithm, and the mostenergy-saving train manipulation scheme is obtained by traversing the solution space. According to the energy-saving manipulation method, ramp potential energy can be fully utilized to provide kineticenergy for the train, the duration of the traction working condition is reduced, and traction energy consumption of the train is reduced.

Description

technical field [0001] The invention relates to the technical field of train operation control, in particular to an energy-saving control method for trains. Background technique [0002] Under the same section running time, there are many different strategies and schemes for subway train manipulation. Different maneuvering strategies and schemes lead to different traction energy consumption of trains. Reasonable train handling methods can achieve the purpose of reducing train traction energy consumption by optimizing the sequence of traction, cruising, coasting, braking and other working conditions and their transition positions during train operation. [0003] At present, the widely used train energy-saving control method in the prior art is maximum traction-cruising-coasting-maximum braking, and the train uses four working conditions in sequence during operation. According to this control method, when the train is running on a section with a relatively gentle slope, the ...

[0004] The disadvantage of the energy-saving control method for trains in the prior art is that when the train is running on a section with a long downhill slope, the traditional four-stage control method based on maximum traction-cruising-coasting-maximum braking may have a long cruising section. A situation where time uses the brakes to maintain a constant speed, a process that does not make efficient use of the ramp-addition force provided to the train by the downhill ramp

Although regenerative braking energy can be generated for use by the vehicle or other vehicles during braking, there must be losses in the process of generation, transmission and utilization of regenerative braking energy, which is not conducive to train traction and energy saving.

In addition, the braking process will generate a large amount of heat energy, resulting in an increase in the temperature in the tunnel, which may affect the stability and safety of electrical equipment in severe cases, and will also increase the energy consumption of the platform air conditioner
