Your library or personal account may give you access

Abstract

Concentrating solar thermal systems operate on the beam component of solar radiation and may experience severe operating transients when dense clouds partially or totally obstruct the collector field. Nowcasting with camera systems aim to predict cloud passage over a collector field at the time scales of 0 to 30 minutes in order to maintain acceptable operating conditions and prevent thermal fatigue of materials. This presentation offers an overview of ground based imaging for nowcasting research activities at the Australian National University.
