METHOD FOR OPERATING A THERMOELECTRIC SOLAR PLANT

SUMMARY Method of operating a solar thermoelectric power plant that allows operation of high-, medium- and low-pressure superheating turbines with both superheated steam and saturated steam. The plant needs to have energy storage in high-pressure steam tanks. The method described allows the direct introduction of saturated steam into a superheated steam turbine. This steam receives an intermediate reheating between the high-pressure turbine and the low- and medium-pressure turbines to achieve conditions of superheated steam. The mode of operation proposed in the invention facilitates the operation of the plant in periods without sunshine (during transient periods, such as passing clouds or night time) or during discharge of accumulators (saturated steam tanks at high-pressure).
