100KW光伏-燃料复合发电系统设计

北京理工大学珠海学院2020届本科生毕业设计Design of 100KW photovoltaic-fuel cell composite power generationsystemAbstractWith the rapid development of society and the reduction of fossil energy storage,theenergy crisis is becoming more and more serious,so the use of new energy power generationinstead of fossil energy power generation is the future trend.At present,photovoltaic powergeneration technology has become increasingly mature in China.For independent solarphotovoltaic energy systems,the use of photovoltaic power generation systems is restricteddue to the problems of large pollution,short life,and intermittent sunlight.The combinationof fuel cells and photovoltaic cells can be used reasonably,so that when the light intensity iscontinuously lower than the average value,the output curve of the photovoltaic cell will notfluctuate greatly.This design refers to the successful cases of photovoltaic fuel cell composite powergeneration systems at home and abroad,focusing on photovoltaic power generation systems,fuel cells as supplements,combined with electrolytic systems and hydrogen storage systems,to design a set of medium-sized photovoltaic fuels that are suitable for factory electricityCompound power generation system.This design selects materials and equipment by comparing the advantages anddisadvantages of different types of solar panels and fuel cells.Then,the structure and powersupply mode of the entire system are designed,priority generation is used,and the remainingenergy is sold to the national grid through grid-connected operation.Finally,the relevant datais calculated to provide a theory for the establishment of a plant photovoltaic-fuel cellcomposite power generation system reference.Keywords:Photovoltaic power generation;fuel cell;photovoltaic-fuel hybrid powergeneration system;electrolyzer;hydrogen storage device
