Problems solved by technology

[0004] Due to the large number of parameters and strong coupling, the current research on energy management control strategies and the research on optimal driving are mostly separated, and this is also limited. Therefore, a method that considers both energy management and optimized driving is proposed. The control method is very meaningful for the safe and stable operation of the train and the maximum energy saving and emission reduction capacity

Embodiment Construction

[0041] like figure 1 Shown is the schematic diagram of the single-particle model of the train, where F dr Indicates the traction or braking force provided by the traction motor to the train (positive numbers indicate traction, negative numbers indicate braking), F f represents the resistance to the train, F N It represents the support force received by the train, and mg represents the gravity of the train. Accordingly, the train kinematics equation can be expressed as:

[0042]

[0043] In the formula, s represents the running distance of the train; v represents the speed of the train; M represents the equivalent mass of the train.

[0044] like figure 2 The equivalent circuit model of the power battery is shown. Among them, U ocv Indicates the open circuit voltage of the battery, R o Indicates the internal resistance of the battery, I bat Indicates the output current of the battery, P bat Indicates the output power of the battery. Therefore, the equation of stat...

Description

technical field [0001] The invention belongs to the technical field of optimal driving and energy management and control of rail vehicles, in particular to a control method integrating optimal driving and energy management of non-contact power supply trains. Background technique [0002] Lithium batteries are increasingly becoming an important part of train power systems due to their high efficiency, cleanliness and renewability. As the key technology of non-contact power supply train, the quality of energy management control strategy directly affects the energy utilization efficiency during train operation. In order to maximize the effect of energy saving and emission reduction for non-contact power supply trains under the constraints of the entire line operation, it is necessary to ensure that the energy management strategy has a good overall situation. [0003] The state of health of the lithium-ion battery is related to the change of the state of charge during the use o...
