Abstract: A drive assembly for a heliostat is described, wherein the drive assembly may be configured to dynamically adjust the position of an attached reflector in concentrated solar power applications. The drive assembly may be further configured to provide for biasing of the reflector to reduce backlash due to external loads. The biasing force may be provided by at least one of a spring, counterweight, or offset of the center of gravity of the reflector or other attachment, or some combination thereof.

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: A system and method for detecting heliostat failures in a concentrating solar plant, the system comprising a plurality of stationary lights and cameras mounted to towers that surround, or are situated within, a field of heliostats. Heliostats may be commanded via a control system to move to a position wherein light may be expected to be reflected from a given stationary light to a given camera, whereupon a first set of images of the heliostat are taken. Heliostats may then be commanded via the control system to move to a position wherein light may no longer be expected to be reflected from said stationary light to said camera, whereupon a second set of images of the heliostat are taken. An image processor may search the first and second set of images to determine if reflected light is present. If reflected light from said stationary light is not found in the images, the heliostat may be determined to have experienced a failure mode. Failed heliostats may then be flagged for inspection, repair, or replacement.

Abstract: An automated deflectometry system and method for assessing the quality of a reflective surface for use in a concentrating solar power plant. The deflectometry system comprises a holding fixture for mounting a heliostat reflector opposite a target screen having a known pattern. Digital cameras embedded in the target screen take pictures of the known pattern as reflected in the surface of the reflector. Image processing software then detects the features of the pattern in the reflector images and calculates the slope profile of the reflective surface. The slope field can be calculated by comparing the images of the reflective surface to those of a reference surface. Based on the slope profile of the reflective surface, a ray tracing calculation can be performed to simulate flux as reflected from the reflective surface onto a receiver and a quality metric can be ascribed to the heliostat reflector. The result of the quality assessment can displayed using a graphical user interface on an automated assembly line.
