In this paper, a diagnostic technique for the detection of rotor inter-turn short circuit faults in Doubly Fed Induction Generators (DFIGs) for wind power systems is designed. The aim is to improve the monitoring system of the DFIG through an appropriate maintenance, enhance operation and increase the reliability to extract the maximum of the wind energy. In this context, an advanced maintenance strategy based on the combination of the Time Synchronous Averaging (TSA) method and Discrete Wavelet Transform (DWT) is established. The proposed strategy has been implemented and verified using simulations built in MatLab O SIMULINK environment. Various scenarios have been conducted for both faulty and healthy states of the rotor. The simulation results demonstrate the reliability and the efficiency of the proposed approach.

Today, with the rising cost of fossil combustible, thermal efficiency is a necessity in the design and the manufacture of all gears. In gas turbines, the thermal barrier coatings increase the thermal efficiency by providing a thermal protection to the parts operating at very high temperatures and avoids also accidents that have serious consequences, especially for airplanes and ships. Controlling the thickness uniformity of these thermal barrier coatings is very important to have a good thermal efficiency of the alloys and a good performance. In this work, using the data of pulsed and lock-in infrared thermography controls, a neural algorithm is proposed to evaluate the thicknesses of thermal barrier coatings irregularly deposited on alloys. The neural algorithm combines the neural network quality and the genetic algorithm advantages. The neural network is trained using the phases calculated by the Fourier transforms of the temperatures. The genetic algorithm is used to optimize the neural network by searching the initial weights matrix inducing a rapid convergence to the optimal solution. This method has improved the network learning by minimizing the mean squared error and the number of iterations. The obtained results by the neural algorithm have shown that both thermal control methods are very effective in estimating the thermal barrier coatings. The thicknesses have been estimated with uncertainties less than 5%.

In this paper, a state-space model of the three level boost converter (TLBC) is presented. A method of control of based on the self-turning fuzzy controller (STFC) is proposed in order to regulate the output voltage of the TLBC. A classical PI controller is used to ensure the balance between the two capacitor voltages. The simulation results show the validation of the proposed method, confirmed by MATLAB/Simulink.

This study focuses on the wind energy conversion systems which consist of a turbine, multiplier, generator and power electronic devices. In our case we opted for the doubly fed induction generator (DFIG); this choice is due to its advantages as well as its ability to adapt to changing wind. On the other hand, this machine is characterized with its non-linearity. Moreover, it is necessary to apply a control in order to have a maximum of power and to maintain the reactive power at zero. Therefore, we will start with the modeling of the system. Then, the maximization of the power using the strategy of maximum power point tracking (MPPT) will be detailed, finally, we will apply the two control techniques namely: direct field oriented control (DFOC) and indirect field oriented control (IFOC) in order to compare them. The results are presented in the Matlab/ Simulink environment to ensure the performance of the control.

In this paper, dye sensitized solar cells (DSSCs) based on triphenylamine-thiophene are investigated by using density functional computations. The main focus is on the C214 and C215 dyes and their resulting bridged free and adsorbed molecules on the semiconductor (TiO2)9, during the electron injection process. The optimized geometry of the molecule and complexes are calculated by using B3LYP/6-31G(d)//(base LANL2DZ for the titan atoms) level, in order to investigate the effect of the expansion, or bridging the thiophenic pi-conjugated spacer by the C(CH3)2 donor group on the adsorption energies, charge distribution, electron transfer and electronic parameters of the resulting dye. The computational results suggest that our bridging process promotes the adsorption on the semiconductor (TiO2)9 of the dyes having the bridged donor group close to the surface of (TiO2)9 C214-B, C215-D bridge dyes by a reinforcement of the donating as well as accepting electrons character, respectively, of the donor part (TPA-thiophenesbridged) and cyanoacrylic acid. This study may help to understand well the details of the electron transfer mechanism between the dye and the TiO2 semiconductor in DSSC dye solar cells.

Wastes generated during the production of olive oil are considered as the Achille’s heel of this activity. Indeed, they represent a serious threat for the environment. One of the alternatives to remedy this problem would be the exploitation of these wastes (especially olive pomace) as a source of energy, given their high calorific potential. The particles are composed essentially of a wet part, volatile matter, char and ash parts. During the combustion process the particle goes through several stages, including drying, devolatilization or pyrolysis (primary and secondary), and oxidation. The objective of this work is to predict the thermal behavior of the pomace particles and the concentrations of gases produced during the combustion in a fixed bed, using ANSYS Fluent CFD (Computational Fluid Dynamics) software.

The building sector is an activity where the potential for saving energy is important and Morocco is now placing the housing sector and energy efficiency and renewable energies among the national priorities in order to combine security of supply and reduction of dependence on energy, environmental preservation, reduction of energy consumption and thermal comfort. As part of the national energy strategy, several actions have been initiated, the Energy Efficiency Code in the building, including the Thermal Regulation of Construction in Morocco, through the Decree of Urbanism approving the General Construction Regulation setting the Energy Performance Rules for buildings. This paper presents the good practice of the control of the energy by using the principles of the passive architecture, solar architecture and bioclimatic architecture, and by adopting the passive energy efficiency for two house building case studies (Villa in Marrakech and modern Moroccan house in Midelt), both situated in severe climate conditions. The approach method analysis covers 3 thematic subjects: 1) the architecture and building relationship with the climate; 2) the usage and the thermal comfort; 3) the energy management and the performance according to the Moroccan thermal regulation. Investigation and methodological tools were based on the documentation, technical information including numerical modeling, plans, sections, photos, and survey of architects, occupants and building users to describe the process, from design to completion, technique and materials used, lessons learned in terms of the energy needs and the design of the indoor thermal comfort.

The purpose of the present work is to investigate the conception and realization of an electronic card comprised of three main blocs. This card monitors and drives the power supply of a household with wind energy. The device enables the optimization and the management of this power supply as well as that off the electric network, the protection of batteries from overloading and deep discharge following voltage threshold crossings of the temperature and finally the display and transmission of the different parameters of the generated electrical power by the wind energy system. The work is based upon simulation and experimentation. Proteus Isis environment is used for simulating the whole system. Focus is put on the power sources and the battery. The load is represented as a power demand to be satisfied. Moreover, the distribution grid contributes as an appoint system. The electronic card measures the different electrical parameters, through its electrical sensors, which are used in its command blocs built around the microcontroller PIC16F876. Satisfactory experimental results were achieved which allowed deepening our expertise in the design and management of an autonomous wind energy system. On the other hand, more investigation is needed in this field, which is actually being done.

In this paper, we proceed to a daily monitoring of module temperature T and incident solar irradiance G received on south faced tilted fixed photovoltaic solar module modelled by single diode equivalent electronic circuit. We assume that module series resistance Rs and shunt conductance Gp are constant and equal to values corresponding to standard test conditions (STC). We derive new analytical expressions describing variations of photocurrent Iph, ideality factor η and saturation current Is as functions of temperature T and irradiance G, using temperature coefficients available and irradiance coefficients extracted from manufacturer’s datasheet. We determine analytically and numerically variations of photocurrent, ideality factor and saturation current throughout a day. We deduce temporal evolving of maximum power point current Impp, maximum power point voltage Vmpp and module efficiency of Sunmodule plus SW255 polycrystalline silicon based photovoltaic solar module and compare with maximum power point and module efficiency experimental data. We raise a very good agreement between predicted values and experimental measurements.

According to an appropriate approach which takes into account the received and the transmitted irradiance across a solar front-glass, the performance ratio has been calculated. The experimental measurements were carried out over two years of exposure in our solar platform located in Rabat-Morocco. The soiling rate has been concluded via the performance ratio and the result obtained have shown that the soiling rate has marked 7 % during the period of exposure. Using only solar front-glass is simple but quite efficient since it has the utility of restricting losses that can arise in photovoltaic panels.
