Shadows calculation for a set of distances between elements of a PV grid connected plant.
阴影计算光伏电网连接植物的元素之间的距离为一组。

描述----------Description----------
The optimum distance between trackers or static structures of a PV grid connected plant depends on two main factors: the ground requirement ratio (defined as the ratio of the total ground area to the generator PV array area), and the productivity of the system including shadow losses. Therefore, the optimum separation may be the one which achieves the highest productivity with the lowest ground requirement ratio.
跟踪器或静态结构的光伏电网连接植物之间的最佳距离取决于两个主要因素：接地要求比（定义为发电机光伏阵列区域的总接地面积的比例），和该系统包括阴影的生产率的损失。因此，最佳的分离可能是一个与最低地面率达到最高的生产率。
However, this definition is not complete since the terrain characteristics and the costs of wiring or civil works could alter the decision. This function is a help for choosing this distance: it computes the productivity for a set of combinations of distances between the elements of the plant.
然而，这个定义是不完整的，因为地形特征和接线或民用工程的成本可能改变决定。这个函数是一个可供选择，这个距离的帮助：它为一组植物的元素之间的距离的组合计算的生产率。

参数----------Arguments----------
参数：lat
numeric, latitude (degrees) of the point of the Earth where calculations are needed. It is positive for locations above the Equator.
数值，纬度（度）的地球所需的计算点。这是积极的赤道上空的位置。
参数：modeTrk
character, to be chosen from 'fixed', 'two' or 'horiz'. When modeTrk='fixed' the surface is fixed (inclination and azimuth angles are constant). The performance of a two-axis tracker is calculated with modeTrk='two', and modeTrk='horiz' is the option for an horizontal N-S tracker. Its default value is modeTrk='fixed'
字符，选择'fixed'，'two'或'horiz'。当modeTrk='fixed'的表面是固定的（倾斜角和方位角为常数）。两轴跟踪器的性能计算modeTrk='two'和modeTrk='horiz'是一个水平NS跟踪的选项。它的默认值是modeTrk='fixed'
参数：modeRad, dataRad, prom, mapa, bd
Information about the source data of the global irradiation. See calcG0 for details. For this function the option modeRad='bdI' is not supported.
全球照射的源数据的信息。见calcG0的详细信息。对于这个功能的选项“modeRad='bdI'不被支持。
参数：prev
Deprecated, dataRad should be used instead. A G0 object (or something that can be coerced to a G0 object). It is used when modeRad='prev'.
已过时，dataRad应该被用来代替。 AG0对象（或东西，可以强制转换为一个G0对象）。它是用来当modeRad='prev'。
参数：sample
character, containing one of 鈥 |
