Abstract
The inventive solar heat collection system reduces the risk of damage to heat transfer pipes of a high-temperature heat collection device. The low-temperature heat collection device () heats water by sunlight heat to generate steam. The steam-water separation device () separates a water-steam two-phase fluid generated in the low-temperature heat collection device into water and steam. The high-temperature heat collection device () heats the steam separated by the steam-water separation device by use of heat of sunlight reflected by a plurality of heliostats (), thereby generating superheated steam. The heliostat control device () controls angles of the plurality of heliostats so that metal temperature of the high-temperature heat collection device is maintained not to be higher than a threshold temperature set to prevent overshoot of steam temperature at an outlet of the high-temperature heat collection device.
