Analyse de la Performance Energétique de la Centrale de Production d’Electricité de Ras-Djinet

Abstract

A training in situ at the Ras-Djinet power plant of the electricity production company SPE Sonelgaz is carried out. The combined cycle process of the plant is modelled by the Aspen hysys 11 software. The comparison of the operating data calculated and collected on site shows that the model is valid enough to predict the operating parameters of the combined cycle of the plant. The model makes it possible to analyse the sensitivity of the specific overall energy consumption of the cycle (CSE) and the temperature of the exhaust gases of the gas turbine under different operating conditions. The results show that the excess combustion air and the fraction of hydrogen in the combustible gas mixture at the entrance to the combustion chamber of the gas turbine have a very significant influence on the specific energy consumption. For the other parameters, the intensity of the CSE remains insignificant.
