100KW 光伏-燃料复合发电系统设计100KW 光伏-燃料电池复合发电系统设计摘 要随着社会的快速发展和化石能源的储存量逐渐减少,能源危机愈加严重,因此利用新能源发电是未来的趋势。目前,光伏发电技术在我国已日趋成熟。对于独立太阳能光伏能源系统,由于蓄电池具有污染大、寿命短以及太阳光具有间歇性等问题,使光伏发电系统的使用受到限制。合理地将燃料电池和光伏电池组合使用,可以在光照强度连续低于平均值的时候,使光伏电池的输出曲线不会出现较大的波动。本设计通过参考国内外的光伏燃料电池复合发电系统的成功案列,以光伏发电系统为主,燃料电池为辅,结合电解系统和储氢系统,设计一套满足工厂用电的中型光伏燃料复合发电系统。本设计通过比较不同类型太阳能板和燃料电池的优缺点,对材料和设备进行选型。然后对整套系统的结构和供电模式进行设计,采用优先级发电,剩余的电能通过并网的运行形式出售给国家电网,最后对有关数据进行计算,为建立厂房光伏-燃料电池复合发电系统提供理论参考。关键词:光伏发电;燃料电池;光伏-燃料复合发电系统;电解槽;储氢装置北京理工大学珠海学院 2020 届本科生毕业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 generation systemAbstractWith the rapid development of society and the reduction of fossil energy storage, the energy crisis is becoming more and more serious, so the use of new energy power generation instead of fossil energy power generation is the future trend. At present, photovoltaic power generation technology has become increasingly mature in China. For independent solar photovoltaic energy systems, the use of photovoltaic power generation systems is restricted due to the problems of large pollution, short life, and intermittent sunlight. The combination of fuel cells and photovoltaic cells can be used reasonably, so that when the light intensity is continuously lower than the average value, the output curve of the photovoltaic cell will not fluctuate greatly.This design refers to the successful case...
