摘要(Abstract)：

制氢系统建模对于降低能耗、研究综合能源系统中不同能流的交互特性具有重要的意义。分析碱性电解水制氢系统工作原理及物理特性，通过电化学方程和参数拟合，建立了碱液制氢电解槽静态模型。在静态模型的基础上，进一步分析得出电解槽负载的等效电路动态模型，通过采用直流加小干扰电压的方法得到电解槽的宽频域阻抗谱，利用傅里叶分析计算出模型中各阻抗参数的具体值。最后基于所得参数值在MATLAB环境下搭建模型进行仿真，通过与实测数据的比较验证了动态模型的准确性。
Modeling of the hydrogen production systerm is of great significance to energy consumption reduction and the study of the interaction characteristics of different flows in integrated energy systems. The working principle and physical characteristics of the alkaline electrolytic water hydrogen production system are analyzed. A static model of the alkaline electrolyzer for hydrogen production is established through electrochemical equations and parameter fitting. Based on the model, a dynamic model of the equivalent circuit of the electrolyzer load is analyzed. The broadband impedance spectrum(BIS) of the electrolyzer is obtained by using DC plus small disturbance voltage. The values of impedance parameters in the model are calculated by Fourier analysis. Finally, the values are simulated by a model established in MATLAB environment. The accuracy of the dynamic model is verified by in comparison to the measured data.
