传统飞机的辅助动力装置噪声大、碳排放量大、效率低,已无法满足多电/全电飞机的发展要求。而燃料电池具有高能量密度、零排放、使用寿命长、低噪声和高效率等优势。本文建立了燃料电池模型并进行优化,以更好地体现其稳态和瞬态性能。建立了由燃料电池和超级电容组成的混合系统作为飞机辅助能源单元的模型,验证了其电能质量满足GJB181A-2003标准,并与传统辅助动力装置进行对比,显示其在响应速度、效率以及功重比上具有明显优势。
The traditional aircraft auxiliary power plant noise, carbon emissions, low efficiency, has been unable to meet the multi-electric / all-electric aircraft development. The fuel cell with high energy density, zero emissions, long life, low noise and high efficiency and other advantages. This paper establishes a fuel cell model and optimizes it to better reflect its steady-state and transient performance. The hybrid system composed of fuel cell and supercapacitor was established as a model of aircraft auxiliary energy unit, and its power quality was verified to meet the GJB181A-2003 standard. Comparing with the traditional auxiliary power unit, the hybrid system showed its response speed, efficiency and weight Than on the obvious advantages.
