Défauts liés aux systèmes photovoltaïques autonomes et techniques de diagnostic - Etat de l’art

L’efficacité de la production de l’énergie solaire photovoltaïque (PV) dépend essentiellement des conditions auxquelles est soumis le générateur photovoltaïque. Ces conditions peuvent être environnementales, opérationnelles liées au processus de…

Degradation of macrolide antibiotic in water by heterogeneous photocatalysis

Le présent travail porte sur la dégradation photocatalytique d’un antibiotique macrolide nommé tylosine (TYL) dans un réacteur batch en utilisant du dioxyde de titane en poudre (TiO2) et une irradiation artificielle 'lampe 9W-UV. L'efficacité de la…

Design and Construction Criteria of Twin Tunnel: Taking an Adverse Wind Condition Effects on Air Pollution Short Circuit at Tunnel Portals as a case

This paper aims to study the influence of the tunnel portal designs, wind conditions and ventilation rate on the amount of air pollution short circuit from one tunnel tube to the other. These effects are investigated by Computational Fluid Dynamics…

Design and simulation of shortcut current MPPTracking technique to control boost converter

This paper presents the control of boost converter using MPPT techniques in photovoltaic system. The short circuit current technique is characterized by its simplicity and easily realized. The technique is based on the measure of the short circuit…

Design of a neural network control scheme for the maximum power point tracking (MPPT)

This paper proposes a control method for the maximum power point tracking (MPPT) of a photovoltaic system and this with the aim of increasing the output power of a photovoltaic system. An electronic controller is built-in between the photovoltaic…

Design of an autonomous photovoltaic power supply system for Nyabikenke Hospital (Burundi) using the ETAP tool

Our energy future must be based on non-polluting energies with significant resources. Renewable energies are the best candidates, but the intermittency of their production requires finding efficient and environmentally friendly storage means. Solar…

Design of an efficient and compact non hydraulic cotton module builder

The need to produce a better quality product for sale to the cotton textile mills and to reduce labour costs during processing has led to considerable interest in machinery optimization concepts for cotton module builders and gins. Commercial module…

Détection et classification de défauts pour un GPV: Etude comparative entre la méthode de seuillage et réseaux de neurones

Comme tout processus industriel, un système photovoltaïque peut être soumis, au cours de son fonctionnement, à différents défauts et anomalies conduisant à une baisse de la performance du système et voire à son indisponibilité. Permettre de…

Détermination de la vitesse de séchage du Curcuma par analogie au modèle de sorption de Bradley

In Madagascar, the drying of Curcuma consists of exposing them directly to the Sun. This is not always productive. This work aims to provide information on the drying of turmeric by determining the drying curve in order to consider industrial drying.…

Determination of the heat transfer coefficient by convection, according to shape of the baffles (solar air collector)

This experimental study and mathematical modelling aim to improve the heat transfer by convection in different cases of transversal baffles inside a duct of a solar air collector. The study enabled us to formulate a mathematical equation of the heat…
