Targets for heliostat health monitoring

摘要

Disclosed is a system and method including targets for heliostat health monitoring. A controller in communication with a target and the heliostat may be operable to determine heliostat health. The disclosed system and method may be used to automatically focus individual heliostats, as needed, and to generally increase the overall health of a heliostat field.

主权项

1. A heliostat system, comprising:
a heliostat; a target, wherein the target includes an array of photocells; and a controller in communication with the target and the heliostat, the controller operable to determine heliostat healthy by comparing a size and a distribution of a mapped image to a predetermined image, the mapped image corresponding to the light reflected onto the target by the heliostat, comparing the distribution and a shape of light at the array to a predetermined image, and ordering a heliostat adjustment when the shape exceeds the bounds of the predetermined image.
