Abstract
A solar thermal electric power system, in which a solar collector, a heat storage vessel filled with a thermal storage material adapted to effect a phase change between solid and liquid internally, a turbine, a condenser, a condensate storage tank, a feed water pump are connected in a closed loop by suitable conduits. A first control valve is provided en route between the solar collector and a heat storage vessel. An steam accumulator filled with water is connected via a second control valve in a pipe route between the solar collector and the first control valve, as well as to a pipe route between the first control valve and the heat storage vessel via a third control valve. The temperature of a fluid flowing out of the solar collector is detected, and when the temperature detected is to be lower than a set temperature, then the first control valve is controlled so as to be closed, while the second control valve is opened.
