  摘要:大型地面电站及分布式屋顶电站是现阶段大规模利用光伏发电的主要方式。在实际应用过程中往往存在位于偏远地区、屋顶资源分散、太阳能辐照仪所绘制的辐照曲线与实际发电曲线不能完全匹配的问题。
 
  本课题针对当前大型地面电站及分布式屋顶电站系统运行特点,结合信号采集理论,对各类光伏电站的汇流箱进行改造,增加基于Internet的数据采集系统。该系统除完成光伏系统的常规电压、电流数据采集以外,还可以实现间接测量数据的采集,包括根据光伏电池组短路电流计算太阳能辐射值的测量,输入输出功率的测量。该系统避免了使用价格昂贵太阳能辐射仪的测量方法,还可供监控人员进行远程监测。

  Abstract:Recently,large-scale PV stations and distributed-rooftop PV stations are the two main modes of PV stations.Large-scale PV stations always locate in remote areas. Roof resources are scattered. And the curves drawn by solar radiation meter are not exactly matched the output power curves of PV stations.
 
  The thesis according to these characteristics ofPV stations and Data Acquisition Theory, gives a method of transforming the junction box and adding the Internet-based communication module. In this way, the new junction box could not only collect the photovoltaic system voltage and current data, but also collect the indirect data. Such as daily solar radiation calculated by the short circuit current of PV string; input and output power of the PV system. The thesis avoids the using of expensive solar radiometer, and can be monitored by the operators.
 
  Key words: Photovoltaic power generation system; Daily solar radiation; Data collection
