Abstract

A solar thermal power system includes a solar receiver for heating thermal energy storage fluid and be stored and utilised from a thermal energy storage arrangement having hot and cold storage tanks. The system includes a steam generator arrangement, which utilises the heat of the thermal energy storage fluid to produces steam to run a turbine. The arrangement includes a bypass line configured to bypass the hot storage tank from the steam generator arrangement, and to supply the hot thermal energy storage fluid from the solar receiver directly to the steam generator arrangement , during day times, when the solar receiver the steam generator arrangement are both in operating mode, thereby recovering stored potential energy available in the down corner hot thermal energy storage fluid from the solar receiver.

Description

technical field [0001] The present disclosure relates generally to the field of concentrated solar energy, and more particularly to a concentrated solar thermal plant with a thermal energy storage fluid that utilizes concentrated solar energy to store thermal energy and utilizes the stored thermal energy to generate electricity. Background technique [0002] A direct steam central receiver (DSCR) based solar thermal plant consists of a large field of heliostats and solar receivers placed on towers of sufficient height. Heliostats focus direct sunlight onto a solar receiver to generate steam that runs a steam turbine to generate electricity. Typically, solar thermal plants operate on a diurnal cycle during clear sunny hours and are shut down at night or in cloudy weather. However, solar thermal plants need to be operable regardless of the availability of solar radiation, ie at night or in cloudy weather, if they are to meet the increased electricity demand. The realization ...
