摘要
以碱性水电解制氢系统为例，阐述了系统各部分的耗电原理及功能，分析了不同负荷下电解槽和辅助系统的电耗变化趋势。研究发现：电解槽交流电耗受直流电耗、法拉第效率和电源效率共同影响，辅助系统电耗与运行套数有关；当电解槽工作负荷在50%以下时，减少辅助系统运行套数可降低系统总电耗；当电解槽工作负荷为50%~80%时，电解槽交流电耗和辅助系统电耗双重影响达到平衡，系统总电耗最低；当电解槽工作负荷在80%以上时，系统电耗主要受电解槽交流电耗影响而升高。最后，对大规模制氢系统的设计和运行提出建议。Abstract
In order to analyze the economic operation of the hydrogen production system,the power consumption principles and functions of each part were illustrated, and the power consumption change trends of the electrolyzer and the auxiliary system under different loads was analyzed taking the alkaline water electrolysis hydrogen production system as an example. The research findings are as follows: The AC power consumption of the electrolyzer is jointly affected by DC power consumption, Faraday efficiency and power supply efficiency, while the power consumption of the auxiliary system is related to the number of operating units. When the load of the electrolyzer is below 50%, the total system power consumption reduces with the decreased number of operating units of the auxiliary system. When the electrolyzer load is between 50% and 80%, the dual influences of the electrolyzer\'s AC power consumption and the auxiliary system\'s power consumption reach a balance, and the total system power consumption is the lowest. When the electrolyzer load is above 80%, an increasing trend of the system power consumption was observed, which can mainly be attributed to the influence of the electrolyzer\'s AC power consumption. Based on this, the author puts forward suggestions for the design and operation of large - scale hydrogen production systems. 关键词
