摘要
针对聚光光伏电站接触器经常替换影响发电效益的问题,采用了建立接触器替换经济性模型的方法,对装置的追日效率和接触器使用频度分析,设计出新的调度方案。通过对聚光电池模组的入射角和短路电流进行分析,建立接触器经济性模型;设计出均分成不同档数的程序;并对所分成的档数进行验证。试验结果表明,光照较强的情况下,适宜采用3档的分档方式,经济效益最优,当光照较弱时,均分5档经济效益最优。
The study is based on CPV tracking control system, making models of electric energy production and economical efficiency of replacing contactor by experiments and numerical simulation. Thus, we can analyze the dispatching mode. The results prove that： if you divisive the whole data equally, the more you divisive the higher efficiency you will get. Meanwhile, we analyze the case that divisive unequally, and design a program to get the division threshold. Finally, we get the most optimal scheduling mode, which can improve the precision of sun tracking device, and reduce the changing frequency for contactors.
