摘要
通过研究由太阳能电池板、蓄电池、变流器和开关电器组成的光伏发电系统,并根据太阳能电池板和蓄电池特性,以及现场实际情况和系统稳定运行要求,在太阳能电池最大功率点跟踪(MPPT)控制技术和蓄电池充放电控制等方面提出了独特的设计方案。对蓄电池电能并、离网两种工作模式的控制策略进行了深入研究,设计出额定功率为50 kW的光蓄互补发电系统用变流器和光蓄互补实验平台。利用该实验平台进行MPPT实验、蓄电池充放电和离、并网实验。实验结果验证了提出的硬件设计和控制策略的正确性和有效性。
The photovohaic power generation system is studied,which composed by solar panels, battery, converter and switching electrical.According to the characteristics of solar panels and battery,the actual situation and the requirements of the stable system,the unique design is put forward,which in maximum power point tracking(MPPT) and charging and discharging control of battery.The control strategies of the two kinds operating mode of electric power grid and battery from nets are researched.The test platform of photovohaic battery hybrid power generation system which rated power 50 kW is designed.Experimental results verify the correctness and effectiveness of the proposed design.
