However, their low thermal efficiency may make the continuous baseload operations a lossmaking alternative and threaten to continue. This fact is raising the importance of performing thermodynamic investigation according to the current operations� conditions. This paper aims to conduct a thermodynamic investigation for two Siemens V94.2 gas turbine (GT) units based on current operations� conditions. The reason for selecting these units is because they are operating at a much lower thermal efficiency than the designed thermal efficiency, and due to the age factor, the GTs are not suitable for major retrofitting due to poor return on investments. A numerical model is designed to simulate the overall thermodynamic process in the gas turbine using MATLAB SIMULINK. The obtained numerical results are validated by comparing them with the operational data collected from the stations. The thermal efficiency is increased by 30%, with a maximum output power equal to 140MW. The power output had decreased by 0.2% when the ambient temperature was increased by about 6.0 oC. A graphical optimization, where various conditions are plotted as graphs, is also carried out to achieve the maximum thermal efficiency and power output. Finally, a number of recommendations are made to address decreased thermal efficiency and output power. � 2021 The Author(s) Final 2023-05-29T09:05:31Z 2023-05-29T09:05:31Z 2021 Article 10.1016/j.egyr.2021.08.202 2-s2.0-85122838605 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85122838605&doi=10.1016%2fj.egyr.2021.08.202&partnerID=40&md5=32d4197a758350caae4263120ba7c4a4 https://irepository.uniten.edu.my/handle/123456789/25910 7 5722 5732 All Open Access, Gold, Green Elsevier Ltd Scopus |
