Performance Analysis of 50MW Parabolic Trough Solar Thermal Power Plant under Makkah City Climatological Conditions

This study examines the energetic and exergetic performance of a concentrated solar power (CSP) plant that uses parabolic trough collectors (PTC) based on Makkah Climatological Conditions. by utilizing steam power block with six heaters and turbine extraction lines, three heaters also are running at high pressure., letting the remaining three be operated at low pressure along with a deaerator, The (CSP)plant produces 50 MW of electricity. Additionally, a calculation model was created to predict the plant's energy generation utilizing the proposed CSP plant concept design and solar irradiation data of Makkah city. Investigations are made into the study of the first as well as second laws of the cycle thermal in addition to exergy efficiency. The results show that with LS-3 collector type a 246, 885m^2of aperture area and a full plant area of 976, 416 m^2is enough to cover annual electricity of 117.2 GWh. The solar field outlet temperature is 3920C with a corresponding daily energy efficiency of 65.6%.The daily average power cycle energy and exergy efficiencies are found to be 39.4%, and 33.5%, respectively.
