A method for optimize operation control of fuel cell hybrid electric train

Abstract

The invention discloses a method for optimize operation and control of a fuel cell hybrid electric train. The method includes the steps of: inputting train information and line information for off-line analysis; based on the online energy management method, comparing the equivalent hydrogen consumption and the regenerative braking energy recovery rate index without obtaining the speed limit constraint and time constraint, obtaining the speed-position curve; increase the line interval speed limit constraint, improve the speed- position curve; increase the running time constraint, improve the offset of the idle line point and the braking point by the advance idle line and multi-objective optimization method to obtain the final speed position Curve; the driver controls the train operation through the final speed-position curve.The invention can effectively improve the energy utilization rate in the whole train operation process, and utilizes regenerative braking energy to the maximum extent on the basis of punctuality and comfort. It greatly reduces the driverworkload and improves the comfort of 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
