    In many places of the earth crust there are fine sediments of eolian origin with collapsible characteristics, and residual soils with expansive features. In general, these soils are found with very low degrees of saturation. When the degree of saturation in fine eolian sediments increases, they suffer collapse because of the leaching of the calcium carbonates and the softening of the little clay, holding the intergranular structure. In the case of residual soils of expansive characteristics, the increase in the degree of saturation produces a reduction in the bond between the grains and the swelling of the clay mineral takes place, inducing important changes in the mechanical behavior such as irregular vertical displacements of the ground surface and of the engineering constructions on top of it. It is therefore, necessary to learn the quantitative parameters that govern the static and dynamic behavior of this type of soils with respect to the moisture-related environmental changes. Basic investigation is important and required in soil mechanics and foundation engineering and it shall be performed on the different types of soils found in nature. [Spanish] En multiples lugares de la corteza terrestre existen sedimentos eolicos finos de caracteristicas colapsibles y suelos residuales con propiedades expansivas, los que en general se encuentran con grados muy bajos de saturacion. Cuando aumenta el grado de saturacion en los sedimentos eolicos finos, que sufren un colapso, debido a la lexiviacion de los carbonatos de calcio y al reblandecimiento de la poca arcilla, que sostienen la estructura intergranular. En el caso de los suelos residuales de caracteristicas expansivas, el aumento en el grado de saturacion provoca reduccion de la adherencia entre los granos e hinchamiento del mineral de arcilla, ocasionandose cambios importantes en el comportamiento mecanico. Lo anterior provoca deformacion irregularse en la superficie de los suelos y en las construcciones que se

    Sizing an electric energy system requires an analysis of investment, maintenance and operating costs. In the case of a generation system that uses renewable sources, optimal capacity becomes more complex compared to a conventional system, because of the randomness of renewable resources (wind, solar) and the still high costs of wind and photovoltage generator modules. This work presents the optimal sizing of a wind-solar-fuel cell generation system, minimizing the costs of the system while satisfying the energy demands of an isolated charge. The optimization method used is based on an evolutionary programming technique known as particle swarms (PSO-particle swarm optimization). The generation of energy with a hybrid system is discussed, based on the profile of insolation and wind availability at the site, with the objective of satisfying a specific electric demand. [Spanish] El dimensionamiento de un sistema de generacion de energia electrica requiere un analisis de los costos de inversion, mantenimiento y operacion. En el caso de un sistema de generacion que utiliza fuentes renovables la capacidad optima resulta mas compleja con respecto a un sistema convencional, debido a la aleatoriedad de los recursos renovables (eolico, solar), y a los aun altos costos de generadores eolicos y modulos fotovoltaicos. En este trabajo se presenta el dimensionamiento optimo de un sistema de generacion eolico-solar-celda de combustible minimizando los costos del sistema que satisfaga la energia demandada por una carga aislada. El metodo de optimizacion utilizado esta basado en una tecnica de programacion evolutiva conocida como enjambre de particulas (PSO por sus siglas en ingles: particle swarm optimization). Se plantea la generacion de energia del sistema hibrido con base a la insolacion y el perfil del viento disponible en sitio, con objeto de satisfacer una demanda electrica determinada.

    instrumentation used for this aim. In chapter 5 the exposition of the design of experiments is realized and the first tests are reviewed to find the variation of the coefficient of damping with respect to the parameters that more affect it. The realized test results are shown in chapter 6. Finally in chapter 7, the conclusions and recommendations are given about this work. The main conclusion was that the mass is the factor that produces more variations of the damping coefficient. For the factors of the length and the moment of inertia a significant variation of the damping is not produced. [Spanish] En Mexico asi como en todo el mundo, las lineas de transmision de energia electrica se ven sometidas a vibracion que puede variar segun las caracteristicas del flujo del aire que las produce; para atenuar la vibracion y con esto, las fallas que se pudieran producir, principalmente fallas por fatiga o fractura, se han empleado desde la decada de 1930 amortiguadores eolicos tipo Stockbridge para disipar esta energia. Los principales parametros de un amortiguador tipo Stockbridge son: la masa del contrapeso, el momento de inercia, la longitud del cable mensajero, el coeficiente de amortiguamiento, las propiedades del cable mensajero, etc. Uno de los parametros mas importantes en el diseno de los amortiguadores eolicos es el coeficiente adimensional de amortiguamiento, por lo que es vital saber si este parametro varia conforme cambian las caracteristicas del amortiguador eolico. La presente investigacion se centra en conocer si existe o no una variacion en el coeficiente adimensional de amortiguamiento con respecto a los parametros del amortiguador. En el capitulo 1 se introduce al fenomeno de la vibracion eolica y a sus caracteristicas principales. Se describen los equipos utilizados para la reduccion de la vibracion eolica llamados amortiguadores tipo Stockbridge, y se plantean la definicion y el objetivo de las tesis.

    The most important aspects of wind energy in Mexico, including the potential for generating electricity and the major projects planned are presented here. In particular, the generation costs are compared to those of other energy sources. The results from the simulation of a 100MW wind farm in the Tehuantepec Isthmus are also presented. In addition, the environmental impacts related to the wind farm in the mentioned zone are analyzed. Finally, some benefits of using Probabilistic Safety Analysis are discussed with respect to evaluating the risks associated with events that can occur in wind parks, being especially useful for design and maintenance of the parks and the wind turbines themselves. In particular, an event tree was developed to analyze possible accident sequences that could occur when the wind speed is too great. Also, fault trees were developed for each mitigating system considered, in order to determine the relative importance of the wind generator components to the failure sequences, in order to evaluate the yield of suggested improvements and the optimization of maintenance programs.

    The present investigation project pretends toward analyze the possibility of pumping water using Aeolian energy from the Soto la Marina River to the Contadero Lagoon, through an eight kilometers channel. In order to obtain this objective it is necessary to analyze diverse configurations for Aeolian energy converters as well as to determine the Aeolian potential of the site. An isolated Aeolian energy pumping system will be analyzed, that is to say, without interconnection with the electric power network and another interconnected with this network. In addition, with the installation of meteorological monitoring stations a partial evaluation of the Aeolian resource in the zone will be made. This research project was born as a result of an invitation of the Dr. Eric Gustafson, President of Conservation Mexico A.C. and of Ing. Virgilio Garza, President of the Vigia Group, to participate in a project called Laguna Flamingo. Such project deals with the restoration of a habitat of aquatic birds in the Contadero Lagoon, property of Ing. Virgilio Garza in Soto la Marina, Tamaulipas, Mexico.

These project solutions aim at mitigating the visual impact caused by the wind aerogenerators. Besides the usual location of the wind aerogenerators on the skyline, these alternatives within the project design relate to the placement of wind turbines in the middle and at the bottom of the hillside. Other possible mitigation forms relate to the dimensions and the colour of the wind towers. This study proposes both a non-monetary and monetary analysis of the visual impact related to each project proposal. The final aim of the paper is to analyze economic and financial costs-benefits for each alternative to find out the economic optimal solution.

    The huge amount of information needed to select and characterize wind potential and wind power production has as a common characteristic being susceptible to be mapped. Therefore, the existing information concerning, environmental restrictions, electric network, land use, among others, was used to build maps representing the restrictions to the wind energy exploitation and introduced into a GIS as input data, together with resource maps generated in order to represent the wind parameters necessary for the wind energy characterisation. Some applications were then built in order to enable the calculation of areas, distances, the selection of favourable wind potential regions to wind energy exploitation, and also used to estimate the sustainable wind potential on the Portuguese mainland, as well as the need to reinforce the national electric grid for the optimised development of this form of renewable energy.

    Wind energy is nowadays one of the most cost-effective and practical options for electric generation from renewable resources. However, increased penetration of wind generation causes the power networks to be more depend on, and vulnerable to, the varying wind speed. Modeling is a tool which can provide valuable information about the interaction between wind farms and the power network to which they are connected. This paper develops a realistic characterization of a wind generator. The wind generator model is incorporated into an algorithm to investigate its contribution to the stability of the power network in the time domain. The tool obtained is termed dynamic power flow. The wind generator model takes on account the wind speed and the reactive power consumption by induction generators. Dynamic power flow analysis is carried-out using real wind data at 10-minute time intervals collected for one meteorological station. The generation injected at one point into the network provides active power locally and is found to reduce global power losses. However, the power supplied is time-varying and causes fluctuations in voltage magnitude and power flows in transmission lines. [Spanish] La energia eolica es hoy en dia una de las opciones mas efectivas y practicas para la generacion de electricidad a partir de energias renovables. Sin embargo, el incremento de la penetracion de energia eolica provoca que los sistemas de potencia se vuelvan mas dependientes y vulnerables a las variaciones de la velocidad del viento. El modelado es una herramienta que provee informacion valiosa de la interaccion dinamica entre las turbinas eolicas y las redes de potencia a las que se conectan. El presente articulo desarrolla una caracterizacion realista de un modelo de la turbina eolica. El modelo de la turbina eolica se incorpora a un algoritmo para el analisis de su contribucion a la estabilidad de una red electrica en el dominio del tiempo. La herramienta obtenida se conoce como flujos dinamicos de potencia. El modelo de la turbina toma en cuenta las velocidades del viento y la potencia reactiva consumida por el generador de induccion. El analisis de los flujos dinamicos de potencia que se presenta aqui, se realiza en funcion de los datos reales de la velocidad del viento recolectados en una estacion de monitoreo del estado de Zacatecas en intervalos de 10 minutos. La generacion inyectada en una parte de la red proporciona potencia localmente, reduciendo las perdidas globales del sistema. Sin embargo, la variacion de la potencia entregada por la central eolica causa fluctuaciones de la magnitud de voltaje y de los flujos de potencia en las lineas de transmision.

    Purposes the application of a methodology to optimize the implantation cost of an wind-solar hybrid system, to potencies between 2.250 W and 3.750 W. The developed mathematical model was obtained through the Multiple Linear Regression technique, on the basis of the previous knowledge of variables: necessary capacity of storage, total daily energy demand, wind power, module power and module number. These variables are gotten by means of sizing. Parametric statistical: T-student tests had been used to detect the significant difference in the average of total cost to being considered the diameter of the wind. Parametric statistical T-student tests had been used to detect the significant difference in the average of total cost to being considered the diameter of the wind, F-Snedecor in the variance analysis to test if the coefficients of the considered model are significantly different of zero and test not-parametric statistical by Friedman, to verify if there is difference in the total cost, by being considered the photovoltaic module powers. In decision of hypothesis tests was considered a 5%-significant level. The configurations module powers showed significant differences in total cost of investment by considering an electrical motor of 3 HP. The configurations module powers showed significant differences in total cost of investment by considering an electrical motor of 5 HP only to wind speed of 4 m/s and 6 m/s in wind of 3 m, 4 m and 5 m of diameter. There was not significant difference in costs to diameters of winds of 3 m and 4 m. A computational program was developed to assist the study of several configurations that optimizes the implantation cost of an wind-solar through considered mathematical model. (author)

    The objective of the work is to model wind field in the surroundings of the Spanish Antarctic Base (BAE in the following). The need of such a work comes from the necessity of an energy source able to supply the energy demand in the BAE during the Antarctic winter. When the BAE is in operation (in the Antarctic summer) the energy supply comes from a diesel engine. In the Antartic winter the base is closed, but the demand of energy supply is growing up every year because of the increase in the number of technical and scientific machines that remain in the BAE taking different measurements. For this purpose the top of a closed hill called Pico Radio, not perturbed by close obstacles, has been chosen as the better site for the measurements. The measurement station is made up with a sonic an-emometer and a small wind generator to supply the energy needed by the sensors head heating of the anemometer. this way, it will be also used as a proof for the suitability of a wind generator in the new chosen site, under those special climactic conditions.

    The Donana area holds important fluvial marshes and also hundreds of small-to-medium size wetlands (ponds, water courses and crypto- wetlands) on a sandy cover (an eolian mantle). The wetlands are mostly groundwater dependant and their hydrological properties are controlled by the particular location within the regional groundwater flow net. Intensive groundwater pumping since early in the 1980's has dramatically changed the groundwater flow regime in many areas. Accumulated inter-annual lowering of the piezo metric levels of deep aquifer layers, the preferentially exploited ones, induced a progressive water-table drawdown. This resulted in a decrease of natural water discharge through seepage and phreatic evapotranspiration, thus modifying wetlands water source and hydro period. Hydrogeochemical, environmental isotopes and modelling studies developed allowed to know wetlands functioning and gave insight about how much groundwater pumping and vegetation management contributed to the modification of wetlands hydrology. The system needs about 30 years to go midway between a previous state and the final state after a change has been produced. Currently the system is under unsteady state, and springs, seepages and river flows tend to decrease if current pump age persists. In some areas this is partially compensated by the eradication of eucalyptus trees planted some decades ago. (Author) 55 refs.

    The state of the Ceara imports most of its consumed energy, configuring itself as a region eminently energy importer. However, the manufacture of its wind power Atlas demonstrated a high potential for the generation of electric energy originated from this renewable source. It is known, also, through studies, that this state possesses high potential for the exploitation of solar energy also for the generation of electric energy. A clean option to obtain hydrogen is the utilization of such renewable sources. This work presents results of the application of a model of solar-wind hydrogen energy for the Ceara state and variables such as population, gross intern product, energetic demand, energy imports, fossil fuel and hydrogen prices, income from hydrogen sale, and others parameters. The hydrogen will be produced from the sea water desalinisation, using solar and wind energies. The produced hydrogen eventually will be introduced in Ceara State through three scenarios which are one of, fast introduction, other of slow introduction and other of no introduction of hydrogen.

    The wind behavior of a region can be described by frequency distribution that provide information and characteristics needed for a possible deployment of wind energy harvesting in the region. These characteristics, such as the annual average speed, the variance and shunting line standard of the registered speeds and the density of aeolian power average hourly, can be gotten by the frequency of occurrence of determined speed, that in turn must be studied through analytical expressions. The more adjusted analytical function for aeolian distributions is the function of density of Weibull, that can be determined by numerical methods and linear regressions. Once you have determined this function, all wind characteristics mentioned above may be determined accurately. The objective of this work is to characterize the aeolian behavior in the region of Botucatu-SP and to determine the energy potential for implementation of aeolian turbines. For the development of the present research, was used an Monitorial Young Wind anemometer of Campbell company installed a 10 meters of height. The experiment was developed in the Nucleus of Alternative Energies and Renewed - NEAR of the Laboratory of Agricultural Energize of the Department of Agricultural Engineering of the UNESP, Agronomy Sciences Faculty, Lageado Experimental Farm, located in the city of Botucatu - SP. The geographic localization is defined by the coordinates 22 deg 51' South latitude (S) and 48 deg 26' Longitude West (W) and average altitude of 786 meters above sea level. The analysis was carried through using registers of speed of the wind during the period of September of 2004 the September of 2005. After determined the distribution of frequencies of the hourly average speed of the wind, it was determined function of associated Weibull, thus making possible the determination of the annual average speed of the wind (2,77 m/s), of the shunting line standard of the registered speeds (0,55 m/s), of the coefficient of variation (20%) and of the density of aeolian power average hourly (24,58 W/m{sup 2}).

    With the increasing of energetic demand in several production sectors, the search for renewable energy sources which do not cause negative environmental impacts has become more and more relevant. Amongst all the important factors to decide for installing isolated generation systems as renewable sources or diesel and taking the distribution network to isolated communities, it should be considered the economic viability of those benefits. This study aimed to analyse the hybrid solar-aeolian system installed in an isolated community, in Jalapao/TO. Three scenarios were analyzed: first of them, getting the capital back with MRI = 6% per year; second one, getting the capital back with MRI = 0; and third, without getting the investment back. In all the three cases, O and M costs were considered. The proceeds were calculated from the production at the community workshop, in which the electricity was available. The results indicated that this technology is economically viable if the generated energy is used for production process. It also demonstrated that the third scenario is more interesting for the community, since the contribution per family is only 8% of its incomes. (author)

    The wind energy is an abundant source of renewable energy, clean and available almost everywhere. For its use, studies are needed to adequately describe its intensity for statistical methods and design for wind turbines. The objective is to structure the mathematical methods used to conduct a general description of the wind, to establish a description of the wind regime using the parameters described using the Weibull function and the analytical model of power from a wind turbine, as well as applications of these methods show. This work was developed at Rural Empowerment Lab of FCA/UNESP in Botucatu-SP. For the application of methods were utilized measurements of wind speed and direction, between 2004 and 2005, obtained by anemometer RM Young Wind Monitor-Campbell. As a result, they estimated the wind behavior and distribution of wind in the region, with 78 kWh of energy production, relatively low potential to supply a small house. Moreover, this energy could possibly be applied in ambient illumination, power supply for electric fences and irrigation of vegetables. (author)

    Nowadays Brazil has many isolated communities. This isolation occurs mainly due to territorial conditions. Besides this aspect, the lack of structure produces another isolation, much more harmful, the social one. To promote social inclusion and sustainable development, some requirements are essential. Amongst all of them, the provision of electricity is the most prominent. This study aimed to provide electricity to an isolated community in the Jalapao region, Mateiros city, in the state of Tocantins. It was installed a hybrid aeolian-photovoltaic system, with capacity to produce 9676.80 kWh per year. This electricity system aims to improve the production process, so it was installed at the local community workshop. The results indicate that the system can be sustainable if the community makes use of the electricity generation, using it in the production process. (author)

    The work developed a methodology fuzzy and simulated its use in control of a hybrid system of electric power generation, using solar-photovoltaic and wind energy. Using this control system, we get the point of maximum energy generation and transfer all the energy generated from alternative sources, solar-photovoltaic and wind energy to charge and / or batteries. The model uses three input variables, which are: wind (wind speed), sun (solar radiation) and batteries (charge the battery bank). With these variables, the fuzzy system will play, according to the rules to be described, what is the source of power supply system, which will have priority and how the batteries are loaded. For the simulations regarding the use of fuzzy theory to control, we used the scientific computing environment MATLAB. In this environment have been analyzed and simulated all mathematical modeling, rules and other variables described in the fuzzy system. This model can be applied to implement a control system of hybrid power generation, providing the best use of renewable energy, solar and wind, so that we can extract the maximum possible energy of these alternative sources without compromising the environment.

    Among the different renewable energy technologies, wind provides better possibilities in regions in which this resource is available. The advantages of wind, as well as solar energy technologies are less or none fuel costs and less environmental impacts. According to the current available technology development, the use of hybrid systems of photovoltaic and wind energy presents large opportunities to cover the energy needs of isolated areas, specially in facilities that don't have connection to the national transmission grid. This study presents the different environmental impacts that hybrid systems have (incorporing the landscape impacts as well as socioeconomical impacts) for the electricity generation in Cuba. We conclude that these systems allow an important power generation in Cuba, and that they have neglected impacts to the environment. The use hybrid systems in Cuba are particularly important in ecotourism facilities and other small industries.

    The development and integration of hybrid systems of electrical generation (SHGE) of small capacity: The intention of these developments is its implementation in isolated or far away communities from conventional electric networks, that contribute in the own productive processes of these towns. As part of these work a system of control for their hybrid system wind-photovoltaic- internal combustion machine was developed that operates nowadays in a system installed in Pachuca, Hidalgo, Mexico. However, in the two past years, the GENC has worked, altogether with the Management of Control and Instrumentation of the Instituto de Investigaciones Electricas (IIE) and the Centro Nacional de Investigacion y Desarrollo Tecnologico (CENIDET) (National Center of Research and Technological Development), to incorporate an intelligent control technique in the regulation of the hybrid systems of wind-photovoltaic-machine of internal combustion type. Lemos de Pereira rises that the main problems of the present technology of the SHGE are related to the control and supervision of the power systems. The system that is in charge of the actions of load control and dispatch is denominated supervisory control. This controller supervises the operation of all the components, regulates the entry or exiting of operation of the generation systems, as well as the loads.

    In the last 10 years, more than 15 GW of wind power (Asociacion Empresarial Eolica (Spanish Wind Energy Association), Nota de prensa (Press release) 17 de enero de 2008. http://www.aeeolica.org/doc/NP_080117_Espana_supera_los_15000_MW_eolicos.pdf) have been installed in Spain, of which more than 3.5 GW in 2007. Furthermore, plans are to reach 20 GW by 2010 and there are expectations of an installed capacity exceeding 40 GW by 2020. This article will present the innovative solutions for technical and economical integration that allow to reach such high level wind penetration objectives (the system peaks at around 44 GW and is almost isolated). It will be described how the regulation has evolved from a pure Feed-in-Tariff to a market+premium option, where technical and economic integration has been a priority. Today, approximately 97% of installed wind capacity accesses the Spanish wholesale electricity market. Market integration has been crucial, sending the correct signals to participants to look for the optimum technical solutions. Technical improvements have come from both wind power producers (fault-ride-through capabilities, visibility and controllability of wind power, power production forecasting, reactive power control) and the system operator (specific control centre dedicated to Renewable Energy Sources (RES), new security analysis tools, gaining technical confidence of wind capabilities).

    Renewable energy technologies, as wind turbines, have had a remarkable penetration in power systems worldwide, causing that actual power grids became dependent and vulnerable to the variability of the energy generated by this type of resource. In that sense, power converters provide a crucial function in the performance of the overall electrical system when they are used as links between this type of generators and the power system. In this paper, a matrix converter is proposed as link device, to cope with distorted and variable voltages as the ones found in wind turbines operation where generated voltages are directly dependent on wind's speed. An analysis of its main functional characteristics when it operates subject to distorted input-voltage condition, in order to synthesize a set of output voltages with constant magnitude and frequency and without harmonic distortion, is presented. Numerical simulations and experimental results from a laboratory-scale prototype are presented to validate the converter performance. [Spanish] La gran penetracion que ha tenido la generacion de energia mediante recursos renovables, como los generadores eolicos, en el mercado energetico, han ocasionado que las redes electricas sean mas dependientes y vulnerables a la variabilidad de la energia que se genera con este tipo de recursos.

En el presente trabajo se propone la utilizacion del convertidor matricial como dispositivo de enlace y se analizan sus caracteristicas operativas en casos donde se requiere la generacion de senales de voltaje sinusoidales y con valores constantes tanto en magnitud como en frecuencia a partir de senales variables, situacion que se presenta comunmente en los aerogeneradores donde el voltaje generado depende directamente de la velocidad del

    El Oyameyo, is an ecological site located to the South-West of the Topilejo town, D.F., 19 degree 25` North latitude, 99 degree 5` West longitude and at an altitude of 3100 m. At present, there are 10 families living at this place. They have energy generators to produce their own electricity by means of solar or wind energy using photovoltaic (PV) technology and eolic systems, respectively. There are three different configurations of energy generators: DC regulated PV systems, AC regulated PV systems and one PV-Wind hybrid system. The electrical power installed for the stand alone PV systems are from 48 W-p up to 768 W-p range. Among these, there are 4 PV systems that are configurated in DC regulated systems, and other 6 are AC regulated systems. All these systems use lead-acid battery (scaled or vented) banks to store the energy produced daily by the systems. The PV-Wind hybrid system in formed, at present, by a 5.0 kW wind generator, a PV array of 768 W-p, a 37.8 kW-h storage battery bank and a 5.0 kW DC/AC inverter. In this work, we report the electricity generated, load pattern and overall system performance of the photovoltaic-wind hybrid system. The technical characteristics, energy test on the hybrid system and the experience obtained from energy handling and system maintenance for all the systems are presented. We found that all the systems had shown good performance and users` satisfaction. [Espanol] El Oyameyo es un lugar ecologico localizado al Sur-Oeste del pueblo de Topilejo, D.
