【摘要】
太阳能作为一种巨量的可再生能源,每天到达地球表面的辐射能量相当于数万吨石油燃烧的能量。开发和利用丰富、广阔的太阳能,可以大量减少对环境的污染,进一步实现无碳生态,太阳能既是近期急需的能源补充,又是未来能源结构的基础。但是由于传统不太重视光伏组件的搭配问题,造成很多的浪费,本文针对以往的系统设计方法中存在的种种缺陷和细节,提出了一种新的优化设计方法和组合。
本文概括介绍了光伏系统的组成、运行方式及其计算,着重讨论了对各部分数学模型的建立。主要包括太阳能辐射资源模型、太阳能电池方阵最佳倾角模型、太阳能电池方阵发电量模型、蓄电池状态模型、负载模型。
在此基础上,本文以光伏系统能量损失最小利用最大化为原则,着重研究了最大功率点跟踪的问题和逆变电路的选择、电池板的选用等,做到因地制宜。这些方案具有一定的理论基础和实际应用价值。
关键词: BUCK斩波电路综合优化设计自做实验模型及其应用理论
【Abstract】
Solar energy as a massive amount of renewable energy, daily radiation reaching the earth's surface energy equivalent to tens of thousands of tons of oil burning energy. Development and utilization of rich, broad solar, can greatly reduce the pollution to the environment, to further the realization of no carbon, solar energy is the recent much-needed energy supplement, also will be the future energy structure foundation. But due to the traditional less emphasis on PV module tie-in problem, cause a lot of waste, according to the previous system design method in existence all sorts of flaws and details, puts forward a new method of optimum design bination.
On the basis of this, this article to PV system energy loss minimization using the maximum principle, focuses on the study of maximum power point tracking problems and the selection of inverter circuit, battery plate selection, to suit one's measures to local conditions. These programs have a certain theoretical basis and practical
Keywords: BUCK chopper circuit, integrated optimization design,
since the experimental model and its application to theory
