Fuel cell hybrid locomotive system based on equivalent consumption minimization strategy

Abstract

In order to bring the simulation system closer to the actual locomotive run properties, ease to observe locomotive system response in real-time. The fuel cell hybrid locomotive system established in this paper, consists of 150 kW proton exchange membrane fuel cell (PEMFC) power generation system, DC/DC converter, battery energy store system, three-phase asynchronous traction motor, etc. And designs the fuel cell hybrid power systems energy management strategy based on equivalent hydrogen consumption minimum. As simulation tests shows, Based on traction inverter-fed induction motor of hybrid system, in the energy management strategy of equivalent hydrogen consumption minimum, when the load and speed changes, fuel cell hybrid locomotive system with Inverter-fed induction motor traction can respond accurately and rapidly. Meanwhile, equivalent hydrogen consumption Minimum energy management strategy to reduce the total equivalent hydrogen consumption of the system, reduces the volume and weight of the hydrogen storage device, and improve the economy.
