Heliostat Shape and Orientation by Edge Detection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heliostats of central receiver solar power plants reach dimensions up to 150 m2 with focal lengths up to 1000 m. Their optical properties and tracking accuracy have great influence on the ...
Slope Measurements of Parabolic Dish Concentrators Using Color-Coded Targets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new fast and highly accurate method for measuring the slope errors of parabolic dish concentrators has been developed. This method uses a flat target with colored stripes placed close to ...
Beam Characterization and Improvement with a Flux Mapping System for Dish Concentrators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A flux mapping system able to measure the flux distribution of dish/Stirling systems in planes perpendicular to the optical axis was built and operated at the Plataforma Solar de Almerı́a ...
Slope Error Measurements of Parabolic Troughs Using the Reflected Image of the Absorber Tube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new and fast method for optically measuring the reflector slope of parabolic troughs with high accuracy has been developed. It uses the reflection of the absorber tube in the concentrator, ...
Validation of Two Optical Measurement Methods for the Qualification of the Shape Accuracy of Mirror Panels for Concentrating Solar Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The solar field is the major cost component of a solar thermal power plant and the optical quality of the concentrators has a significant impact on the field efficiency and thus on the ...
Parabolic Trough Optical Performance Analysis Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analysis of geometry and optical properties of solar parabolic trough collectors uses a number of specific techniques that have demonstrated to be useful tools in prototype evaluation. These are ...
