A fuel cell hybrid train optimal operation control method

Abstract

The invention discloses a fuel cell hybrid train optimal operation control method, comprising the steps of: inputting train information and line information, and performing offline analysis; based on an online energy management method, comparing, etc. The effective hydrogen consumption and regenerative braking energy recovery rate indicators are used to obtain the speed-position curve; the speed limit constraint of the line interval is added to improve the speed-position curve; the running time constraint is added, and the coasting is carried out through the method of coasting in advance and multi-objective optimization The offset improvement of the braking point and the braking point is obtained to obtain the final speed-position curve; the driver controls the operation of the train through the final speed-position curve manipulation. The invention can effectively improve the energy utilization rate in the whole running of the train, utilize the regenerative braking energy to the greatest extent on the basis of punctuality and comfort, greatly reduce the workload of the driver, and improve the comfort of the passengers.

Description

technical field [0001] The invention belongs to the technical field of fuel cell hybrid trains, and in particular relates to a method for controlling optimal operation of fuel cell hybrid trains. Background technique [0002] A fuel cell is a power generation device that converts hydrogen energy into electrical energy, and it is clean, environmentally friendly, efficient and safe. At present, fuel cells have been applied in the field of transportation, especially in rail transportation, and its development prospects are even broader. [0003] At present, in the field of rail transportation, related vehicles have been developed at home and abroad, such as station shunting, locomotives, trams, intercity trains, etc. The development trend of fuel cell rail transit vehicles is: passenger train and marshalling. Therefore, it is necessary to study the operation of fuel cell hybrid trains. When analyzing trains powered by conventional power supply systems or energy storage syste...

Problems solved by technology

When the existing control method controls the whole running of the train, due to the limitation of the energy storage system, it is impossible to realize the contractual utilization of energy, which makes the energy utilization rate of the whole train running low; and the energy storage capacity of the fuel cell hybrid train Limited, the regenerative braking energy can be fully recovered, it cannot effectively guarantee the safe and stable operation of the train, and the stability of the energy storage system is poor; it is necessary to control the train after the driver has followed up the current running status of the train in real time to make empirical judgments, so that the load of the train driving process , which increases the workload of the driver and greatly reduces the comfort of the passengers
