ANFIS and ANN models to predict heliostat tracking errors [PDF]
Heliyon, 2023 The efficiency and performance of solar tower power are greatly influenced by the heliostats field. To ensure accurate tracking of reflectors often requires an evaluation of the beam reflected positions. This operation is costly time-consuming due to the

On-Line Measurement of Tracking Poses of Heliostats in Concentrated Solar Power Plants [PDF]
SensorsThe tracking pose of heliostats directly affects the stability and working efficiency of concentrated solar power (CSP) plants. Due to occlusion, over-exposure, and uneven illumination caused by mirror reflection, traditional image processing algorithms ...

Progress in track-mounted heliostat [PDF]
AIP Conference Proceedings, 2020 A novel concept is presented for a track-mounted heliostat for central receiver plants, intended to be manufacturable at low cost and to reach an installed cost of∼$60/m2 when implemented in high volume. Cost reduction is achieved by using steel in the structurally most efficient form of spaceframe structures. These spread the load broadly, halving the

Closed loop optical tracking of heliostats [PDF]
AIP Conference Proceedings, 2019 Accurate tracking of heliostats is a key requirement for cost-effective commissioning and operation of central receiver concentrating solar thermal plants. We explore sensor-based options to enable pointing accuracy of ±1 mrad or better. A driver for this work is the concept of a ‘Drop-in’ heliostat, which has been developed as part of the Australian ...
