介绍了调车机车燃料电池混合动力系统的设计和建模。对比了不同类型的机车燃料电池的应用,建立了燃料电池和辅助储能设备的模型,并且设计了整个系统的控制策略。利用提出的控制策略,功率控制系统调节了燃料电池和包括电池以及超级电容的辅助储能单元之间能量需求的分配。分析了典型调车机车功率占空比的试验数据。通过试验数据,验证了所提出的控制系统。结果显示,在不同电源供电时,这个控制系统有能力保持输出电压在确定的范围以内、保持电池的充电状态在最优区间,并满足机车对高效功率的要求。
The design and modeling of hybrid vehicle fuel cell system for shunting locomotive are introduced. The application of different types of locomotive fuel cell is compared, the model of fuel cell and auxiliary energy storage device is established, and the control strategy of the whole system is designed. With the proposed control strategy, the power control system regulates the distribution of energy requirements between the fuel cell and the auxiliary energy storage unit including the cell and the supercapacitor. The test data of the power duty cycle of a typical shunting locomotive are analyzed. Through the test data, the proposed control system is verified. The results show that under different power supply, the control system has the ability to keep the output voltage within a certain range, keep the battery state of charge in the optimal range, and meet the locomotive requirements for high efficiency power.
