以某氢氨谷综合能源一体化项目为研究对象,分析了风光耦合制氢合成氨系统的工作流程,基于光伏发电系统、风力发电系统、质子交换膜电解池、氢储罐系统和合成氨系统建立了系统的整体机理模型。基于SIMULINK实现了系统在四季条件下的整体模型仿真,从风光出力特性、氢氨产率特性和反应器温度特性对系统展开整体特性分析。研究结果表明风光耦合技术可大幅提高系统供能稳定性；质子交换膜电解池的负荷响应速度较快,而合成氨系统则具有约1 h的负荷响应时间,成为制约风光耦合制氢合成氨系统整体负荷响应速度的主要因素；产氢速率通过改变原料气与催化剂的接触时长影响氨合成效率,从而使得其与反应器温度呈负相关关系。

Taking a comprehensive energy integration project of hydrogen and ammonia valley as the research object, the work flow of the wind-solar coupled hydrogen and ammonia production system was analyzed, and the integral mechanism model of the system was established based on photovoltaic power generation system, wind power generation system, proton exchange membrane electrolytic cell, hydrogen storage tank system and ammonia synthesis system. The integral model simulation of the system under four seasons was realized based on SIMULINK, and the integral characteristics of the system were analyzed from the characteristics of solar power output, hydrogen ammonia yield and reactor temperature. The results show that the wind-solar coupling technology can greatly improve the energy supply stability of the system. The load response speed of the proton exchange membrane electrolytic cell is relatively fast, while the load response time of the ammonia synthesis system is about 1 h, which is the main factor restricting the integral load response speed of the wind-solar coupled hydrogen production ammonia synthesis system. The hydrogen production rate affects the ammonia synthesis efficiency by changing the contact time between feedstock gas and catalyst, which makes it negatively correlated with the reactor temperature.
