Method for determining intensity of circumsolar radiation in solar-thermal power plant, involves determining course and intensity of signal during approaching of shadow tape to position of sun

摘要

The method involves measuring intensity of solar radiation with a light sensor (1) at a predetermined time. A shadow tape (3) is set to shade direct radiation of sun (5). The signal course resulting from shading of direct radiation is analyzed. The course and intensity of signal are determined during approaching of shadow tape to position of sun. The intensity of circumsolar radiation is determined during approaching of shadow tape to position of sun.
