分布式光伏电站阴影计算模型与实例分析是电力学报中的一篇学术文章，主要探讨了分布式光伏电站因周边障碍物产生的阴影对发电效率的影响。在分布式光伏系统中，尤其是在工商建筑屋顶上安装的光伏阵列，由于受到建筑物或其他物体的阻挡，会形成阴影，导致光伏阵列的功率输出下降。文章提出了一种基于屋顶平面坐标的阴影轨迹数学几何模型，旨在精确计算障碍物的阴影范围。

作者构建了一个基于屋顶平面坐标的阴影轨迹模型。这个模型考虑了平屋面和坡屋面等各种复杂工况下的阴影计算。通过数学公式，他们得出了在不同条件下障碍物阴影长度的理论计算方法。这种方法使得在设计和优化光伏系统布局时，能够更准确地预估阴影的影响，从而提高光伏发电系统的整体效率。

接着，文章结合实际案例，运用PVsyst软件对提出的计算方法进行了验证。PVsyst是一款广泛用于光伏系统设计和性能模拟的专业软件，其结果的准确性被业界认可。验证表明，提出的阴影计算模型能够有效地应用于实际场景，预测出阴影对光伏阵列的影响。

进一步的研究通过实例分析了障碍物对光伏方阵采光效率的影响程度。研究发现，光伏方阵距离障碍物越近，年辐射损失就会越大，这直接影响到光伏系统的年发电量和经济效益。因此，在分布式光伏电站的设计阶段，应充分考虑障碍物的阴影效应，合理布置光伏组件，以减少阴影带来的负面影响。

总结来说，这篇论文的核心知识点包括：

1. 分布式光伏电站的阴影问题：由于建筑物和其他障碍物的存在，光伏阵列的功率输出受到影响。

2. 屋顶平面坐标下的阴影轨迹模型：提供了一种数学几何方法来精确计算阴影范围，适用于平屋面和坡屋面。

3. PVsyst软件验证：通过实际案例和专业软件验证了阴影计算模型的准确性。

4. 阴影对光伏系统效率的影响：距离障碍物越近，年辐射损失越大，影响发电量。

这些知识点对于分布式光伏电站的设计、建设和优化具有重要的参考价值，可以帮助工程师更好地理解和解决实际工程中的阴影问题，提高太阳能资源的利用效率。
