SCADA-Based Heliostat Control System with a Fuzzy Logic Controller for the Heliostat Orientation

Applied Sciences, 2019
In central receiver systems, there are local controls that modify the position of the heliostats, where the trend is to increase the intelligence of the local controls in order to give them greater autonomy from the central control.

Characterization of heliostat corrosion

Solar Energy Materials, 1980
Abstract Corroded mirrors from a heliostat exposed at Livermore, CA, for seven months have been characterized by a variety of techniques including optical and electron microscopy, reflectance and transmission spectroscopy, and surface-enhanced Raman spectroscopy.

Review of heliostat calibration and tracking control methods

, 2020
Large scale central receiver systems typically deploy between thousands to more than a hundred thousand heliostats. During solar operation, each heliostat is aligned individually in such a way that the overall surface normal bisects the angle between the

The determination of space parameters of the heliostatic collector field [PDF]

Acta Montanistica Slovaca, 2006
The assurance of perpetual perpendicular insolation of solar collector absorber surface may increase the insolation energy byca 42-45 %.. A consequence of theincrease in the energy production may be the reduction of the solar collectors’ surface area ...

Dynamic conversion of solar generated heat to electricity [PDF]

The effort undertaken during this program led to the selection of the water-superheated steam (850 psig/900 F) crescent central receiver as the preferred concept from among 11 candidate systems across the technological spectrum of the dynamic conversion ...

Developing Deformable Facets for Heliostats: An Increased Solar Concentration for Thermochemical Applications with Central Tower Receivers

SolarPACES Conference Proceedings
In the present article a new design of a deformable facet and a heliostat with several deformable facets is presented. Previous work has been made around designing heliostats with concentrating facets in the facilities of the Plataforma Solar de ...

Extrasolar Planet Transits Observed at Kitt Peak National Observatory

, 2012
We obtained J-, H- and JH-band photometry of known extrasolar planet transiting systems at the 2.1-m Kitt Peak National Observatory Telescope using the FLAMINGOS infrared camera between October 2008 and October 2011.
