Abstract

The invention discloses a train operation optimization method with limited energy and free time, comprising the following steps: S1: collecting basic data of trains, state information of trains, basic data of lines, basic data of energy consumption of auxiliary systems and on-board storage Basic data of energy system status; S2: Get the train running speed curve with the lowest cumulative energy consumption; S3: Determine whether the lowest cumulative energy consumption is less than the remaining power of the train battery, if so, go to step S4, otherwise go to step S5; S4: Get the minimum cumulative energy consumption The energy consumption train speed curve is used as the train speed optimization curve with the lowest cumulative energy consumption; S5: Use the constant speed coasting strategy to obtain the train speed optimization curve with the longest running distance. The invention is applicable to a class of trains with vehicle-mounted energy storage and power supply capabilities, and optimizes the running speed curve of the train in the self-rescue scene of catenary power failure, reduces the cumulative running energy consumption, and expands the running distance of the train with limited energy storage power.

Description

technical field [0001] The invention belongs to the technical field of energy-limited train operation optimization control, and in particular relates to an energy-limited and time-free train operation optimization method. Background technique [0002] With the rapid development of my country's rail transit, the number of trains in operation is huge, and a lot of power equipment is required. Any of these reasons will cause a power outage in the power grid, and the power of the train will be lost. At this time, the train can only rely on the on-board energy storage device for power supply. Due to the limited space of the train and in order to reduce unnecessary energy consumption, the weight and size of the on-board energy storage device should not be too large. Due to the limitation of current battery technology, the capacity of the on-board energy storage device is limited. The power supply of the on-board energy storage device How to safely and efficiently run the train to ...
