本文讨论了燃料电池混合动力机车动力系统的设计和建模。比较了适合机车应用的不同类型的燃料电池，建立了燃料电池和辅助存储装置的模型，并提出了整个系统的控制策略。通过使用所提出的控制策略，功率控制系统调节燃料电池和辅助存储单元（包括电池和超级电容器）之间的功率需求的共享。分析了典型转辙机机车功率占空比的试验数据。所提出的控制系统进行了测试，使用实验数据。结果表明，该控制系统能够将不同电源的输出电压保持在一定范围内，电池的荷电状态保持在最佳范围内，以较高的效率满足机车的功率需求。
This paper discusses the design and modeling of power system for a fuel cell hybrid locomotive. Different types of fuel cells for appropriate application to locomotives were compared, fuel cell and auxiliary storage devices were modeled, and a control strategy for the overall system was developed in this paper. By using the proposed control strategy, the power control system regulates the sharing of power demand between fuel cell and auxiliary storage units including batteries and ultracapacitors. Experimental data of the power duty cycle of a typical switcher locomotive is analyzed. The proposed control system is tested using the experimental data. Results show that the control system is able to maintain output voltage from different power sources within a certain range, keep the state of charge of the batteries within an optimal range and meet power demand of the locomotive at a high efficiency.
