Abstract

Thermal steam power plants are indispensable for global electricity generation. However, assessing their performances under different working loads is crucial for their enhancement. This study aims to develop a comprehensive model using Matlab to simulate the performance of an existing thermal steam power plant (Achouat plant), enhanced with regeneration and re-superheat features. Additionally, an energy analysis is conducted to evaluate its efficiency under both full and partial load conditions. This analysis aims to certify and compare the performance and parameters of different plant components across various operating loads. The obtained results demonstrate that the developed model performs well in modeling the studied plant under various loads. Moreover, the findings affirm that the plant operates most optimally at full load and higher operating loads, showcasing an overall energy efficiency ranging from 33.24% to 37.38% across operating loads from 20% to 100%. 

Keywords
