碱性电解水制氢系统建模与仿真OA

The existing alkaline electrolysis hydrogen production technology primarily focuses on performance testing of electrolyzers and optimization of flow fields in electrolysis cells,and little attention is paid to overall description of the hydrogen production system as well as the mechanism modeling and simulation of key equipment.To solve this problem,using gPROMS process simulation software and referencing chemical process simulation methods,a distributed parameter model based on mechanism analysis was established for a 200 m³/h(standard condition)alkaline water electrolysis hydrogen production system.The key equipment of the system was finely modeled and simulated.By comparing the simulation results with experimental data,the results show that the simulated values of the main performance parameters of the system have good consistency with the measured data.The calculated average error is less than 5%,which verifies the effectiveness of the model.The established model can describe and predict the changes in system parameters,providing methods and support for subsequent system design,optimization,and control.
