Abstract: A heliostat array having a variable field density for use in a concentrating solar power (CSP) plant. Heliostats are arranged into subgroups and configured to track the sun and reflect light to a receiver tower. Heliostats are deployed onto structures, wherein the structures can be arranged in rows separated by a service gap. The structures can comprise cross members that can be varied in size. By altering the size of cross members in a structure, heliostats in one row can be deployed farther apart or closer together than heliostats in a different row. Heliostat field density can vary with distance from the receiver tower, wherein heliostats close to the receiver are more tightly packed and heliostats further from the receiver are spaced farther apart. Heliostat subgroups can exhibit variable heliostat density using one or more of the following features: variable spacing of heliostats within the same row, variable spacing of heliostats mounted to the same structure, or by varying the width of the service gap between rows. The result is a field configuration that reduces the blocking and shading of heliostats by their neighbors.

Abstract translation: 一种具有可变场密度的定日镜阵列，用于集中太阳能发电（CSP）设备。 定向日光灯被安排成亚组，并配置成跟踪太阳并将光反射到接收塔。 定向器部署在结构上，其中结构可以排列成由服务间隙分开的行。 结构可以包括尺寸可以变化的横向构件。 通过改变结构中的横梁的大小，一行中的定日镜可以与不同行中的定日镜更远或更近地部署。 定向射线场的密度可以随距接收器塔的距离而变化，其中靠近接收器的定日镜更紧密地包装，并且远离接收器的定日镜间隔更远。 使用以下特征中的一个或多个可以显示日光反应器密度变化的定日照射密度：同一行内的定日镜的可变间距，安装在相同结构上的定日镜的可变间隔，或者通过改变行之间的服务间隙的宽度。 结果是一个现场配置，可以减少其邻居对定日镜的遮挡和遮蔽。
