Numerical simulation of solar gas turbine power plant with combined cycle in South Algeria

Abstract

Modelling and thermodynamic study of concentrated solar power plants are essential to understanding and predicts the performance of these installations. This paper aims to design a central solar tower gas turbine with a capacity of 11.5 MWe by an adapted simulator and to assess the potential improvement in this installation by adding a Rankine combined cycle with a capacity of 3.5 MWe. The simulation and the modelling study of the installation will be done initially by calculating the matrix of effectiveness of the solar field (Monte Carlo method), then we will proceed a numerical simulation by the software TRNSYS16 and its library STEC.03, of the different components of the installation with taking into account the performances of each element. The main objectives of this study are presented by an energetic and exergetic analysis, and to assess the feasibility of the installation for the climatic conditions of Bechar area located in southern Algeria.
