摘　　要： 为合理有效利用太阳能资源,研究实现了车棚棚顶太阳能发电系统。提出采用光电单轴追踪及超级电容—蓄电池混合电源系统的设计,克服了传统独立光伏系统的缺点,通过在超级电容与蓄电池之间加入boost-buck变换器保证蓄电池充放电的平稳性。结合车棚使用特点,利用储能蓄电池直接对电动自行车进行充电的DC-DC方案来减少因整流逆变造成的损耗。设计了一种基于光电传感器的新型光强追踪结构,采用双推杆进行光强追踪控制。系统的实际测试效果表明,该系统能够准确、有效运行,并具有较大的节能潜力。 To use solar energy reasonably and efficiently, the shed roof solar power system is designed. The design of photoelectric single axis tracking and super capacitor-battery hybrid power supply is proposed to overcome the disadvantages of traditional stand-alone photovoltaic systems. Boost-buck converter is added between super capacitor and battery to keep the charge and discharge current of battery stable. Considering the using characteristics of the shed, a method of charging the electric bicycle directly by DC-DC converter and battery is used to reduce the loss caused by the rectification and inversion. A new light intensity tracking structure based on photoelectric sensor is designed and double push rod structure is used to control the angle adjustment mechanism. The results of actual tests show that the system can run accurately and effectively, and has a great potential for energy saving.
