基于坐标系变换的双轴跟踪聚光光伏电站布局策略

AN ARRAY COORDINATE SYSTEM BASED DUAL-AXIS TRACKING CPV POWER STATION LAYOUT STRATEGY

提出一种基于空间坐标系变换的双轴跟踪光伏电站布局优化策略。通过将地平坐标系中的坐标点转换到矩阵坐标系中,可以精确计算出任意地形上、任意时刻下光伏矩阵间的相互遮挡面积,应用该策略,在有朝向限制或倾斜的场地上布局,能有效避免光伏矩阵在运行时段互相遮挡,同时能充分地节约电站的占地面积。

This paper proposes a dual-axis tracking PV power station layout strategy based on the spatial coordinate system transform. Shadow area between CPV arrays can be accurately calculated by transferring point coordinates from horizon coordinate system to array coordinate system. Applying the recommended policy, the CPV power station layout is optimized in condition sites to avoid CPV arrays shadowing caused by others and to save land consumption.
