1、2010届本科生毕业论文I风光互补发电系统进入二十一世纪,人类面临着实现经济和社会可持续发展的重大挑战,而能源问题日益严重,一方面是常规能源的廣乏,另一方面石油等常规能源的开发带来系列的问题,如环境污染、温室效应等。人类需要解决能源问题,实现可持续发展,只能依靠科技进步,大规模开发利用可再生能源和新能源。而太阳能和风能被看做是最具有代表性的新能源和可再生能源,作为这两种能源的高级利用太阳能发电和风力发电技术受到世界各国的高度重视。由于风力发电和太阳能发电系统均受到外部条件的影响,光靠独立的风力或太阳能发电系统经常会难以保证系统供电的连续性和稳定性,因此,在采用风光互补的混合发电系统來进行
2、和互补充,实现连续、稳定地供电。风光互补发电以其独特优势成为新能源研究的热点之一。木文针对风光互补发电系统设计了一套小型模拟装置,包括太阳能电池模拟,用直流电机对风机的模拟和交错并联Buck-Boost蓄电池充电主电路,并对交错并联Buck-Boost电路和交错并联Cuk斩波电路进行了研究、仿真,以及进行了模拟风机装置的调试。系统控制全部采用Frccscalc公司的56F8013DSP控制实现,给岀了各部分流程图。对于软硬件的关键问题还给fllTffl应解决方案。:风光互补Buck-Boost电路DSP2010届本科生毕业论文IIWind&SolarHybridGeneratingSys
