Modeling and performance study of large parabolic trough solar power plant
using molten slat storage tank is conducted and presented for three different locations
in Egypt (Aswan, Al-Arish and Hurghada) using 16 h storage system. The
simulation algorithm and solar modeling have been created and simulated by MATLAB/
SIMULINK program.Acomparison between studied cities is introduced to select
the best location for constructing the solar plant based on selection criteria; hot header
outlet temperature, volume (hot and cold) variations during charging and discharging,
and cycle power efficiency. A full design of the thermal power plant with the storage
tanks is also conducted using a molten salt (60% NaNO3 and 40% KNO3). Moreover,
hourly electricity plant output to obtain the influence of the thermal storage tank on the
plant performance was calculated and presented. The results indicated that Aswan city
is the optimum location to construct a 500 MW solar power plant under the Egyptian
climate. A comparison for current model validation between simulated results and
the actual results of existing plant (Archimede) was fulfilled and good agreement was obtained by maximum error 5%. |
