| Summary: | 碩士 === 國立成功大學 === 化學工程學系碩博士班 === 101 === In recent years, the global warming has become important issue due of using excessive fossil fuels. In order to reduce the usage amount in fossil fuels, a design of combination solar energy and hydrogen energy for hybrid power generation system in this study. Considering the steady state process, the results indicated that the hydrogen yield can be improved to a certain content in terms of the autothermal reforming of methanol process. Moreover, a combination of PEM fuel cell and solar cell is a novel design to obtain the load requirement.
The present study employed Aspen Plus to simulate hydrogen production process to gain a fundamental insight into autothermal reforming of methanol. At first, We obtain the optimal operation conditions in steady state process, and then remove the disturbance and the tracer of hydrogen set point in dynamic process. Therefore, We can understand the change of loads how to influence hydrogen yield. Than using MATLAB/Simulink to get a block diagram of the mathematical model to simulation each power generation system, analysis the dynamic of its components that change with the load requirements of its voltage, current, power, efficiency and other changes.
According to the results above, dynamic simulation of autothermal reforming of methanol is successfully established in this study. Based on the domestic power consumption in Taiwan, the power generation in hybrid power system is investigated with different time interval.
