electricity by a hybrid thermal power plant exploiting the solar field on the one hand and
natural gas on the other hand. This work concerns firstly the evaluation of the thermodynamic performances of a solargas hybrid thermal power system with a power of 150 MW, the method of energy analysis was used in this thesis. This method is used to determine the main parameters in order to achieve improvements in system performance. The development of the analysis model in this thesis is carried out by determining the thermal and solar efficiency as well as the efficiency of solar electricity. Due to the calculation of the thermal and solar performances in typical days and an average of the days of the year, we used simulation software "Aspen Plus" to determine the thermodynamic parameters of the hybrid plant in the case of Algerian weather conditions. As well as the System Advisor Model (SAM), this gives a methodology and
information particularly on cylindro-parabolic shapes concerning the part of the solar field in the system studied. The results are calculated hour by hour from sunrise to sunset. The second part of this work is being improved in the overall efficiency of the plant with two levels of pressure that directly affects the capacity of the steam turbine in the power block. In the third part, an optimization of the power at the level of the steam turbine is also carried out. The optimization was carried out in the power block which contains two gas turbines and a double pressure steam cycle where the high pressure part is only heated. Preliminary simulations for this system have shown that the steam turbine cycle can achieve optimum conditions for reheating and low vapor pressure, which would enhance the performance of the system. The fourth part concerns the comparison of the key parameters of the thermal power plant in different sites based on the economic factor (LCOE), the configuration of the solar field section and the line spacing or the so-called effect of shading. The exploitation of the "Aspen plus" and "SAM" software enabled us to establish models of optimal hybrid power plants (solar-gas) in the arid zone of Algeria. Such a study is a reference for the construction and site selection of the installation of this type of power plant.Diplôme : Doctorat en sciences En ligne : ../theses/gmecanique/MIL7126.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=10476 Etude du champ solaire d’une centrale thermique hybride de production d’electricite.

Currently, solar drying is among the most important applications of solar energy. This type of drying is one of the most suitable solutions for preserving agricultural products, especially in developing countries. In order to improve the solar drying process, a new indirect solar dryer with natural convection was designed, built, and tested in the climatic conditions of the Adrar region (Algerian Sahara). The construction and experimentation phases were preceded by modeling of the dryer. The heat balances of its main components, drying chamber and solar collector, were established, and the resulting equations were solved by the 4th order Range Kutta method. The effect of many parameters on the drying kinetics was examined. In order to validate on the one hand the numerical results and to demonstrate on the other hand the efficiency of the proposed prototype, measurement companions of many parameters (solar radiation, temperatures of the horizontal and vertical absorbers of the solar collector, temperatures in and at the outlet of the latter, temperature, and humidity of the drying air, water content of tomato and henna products), were carried out for four days, one per season. The results obtained strongly encourage the installation of the proposed indirect solar dryer in the Saharan environment. Such a device will undoubtedly make it possible to conserve the surplus crops of agro-food products and medicinal plants, limit or even eliminate the significant losses recorded each year. Such a device will undoubtedly make it possible to conserve the surplus crops of agro-food products and medicinal plants, limit or even eliminate the significant losses recorded each year. The device will undoubtedly contribute to the socioeconomic development of these desert regions.
