Abstract
A solar tower CSP power plant with a thermal storage system was simulated for comparison between the cities of Dagget (California/USA) and Petrolina (Pernambuco/Brazil) using solar data files of the Meteonorm software, from the Meteotest swiss company, in the Typical Metrological Year 2 format. The computational programs used for the solar power plant simulation were the EES, SAM and TRNSYS. The EES software was used to write the code of the power block subsystem that outputted its needed parameters, for 41,2% of thermal efficiency, in TRNSYS. The SAM software was used to determine the parameters of the solar field and the thermal storage subsystems, in their most profitable setups, used in TRNSYS simulation, for each city. Finally, the solar tower CSP power plant was simulated in the TRNSYS software outputting the interrelationships between the three subsystems during a typical year. The behaviors of the plant in the solstices and equinox were plotted and the simulated power plant in the city of Petrolina had a solar field with 55.4% more heliostats for an annual energy production and a capacity factor 11.2% and 8,5% lower than Dagget respectively.
