SOLAR THERMAL POWER STATION WITH EXERGETIC MANAGEMENT OF HEAT

摘要

The invention relates to a solar thermal power station with exergetic management of heat, in order to operate under nominal conditions for long periods of time every day. The power station is divided into sectors with different heating functions, in which each sector has its own heating fluid, but all of the sectors consecutively receive the same working fluid for the thermodynamic cycle. Each sector includes: an array of solar collectors (1), a main exchanger (2) in thermal contact with the working fluid, an indirect heat storage system and a direct heat storage system, as well as the pumps, valves and instrumentation necessary to configure each sector according to three different circuits, thereby allowing heat energy to be stored when the captured solar radiation is above the nominal value and for this heat to be used to operate the thermodynamic cycle under nominal conditions when the radiation value falls below the nominal value.
