Wind turbines consists of three key parts, namely, wind wheels (including blades, hub, etc.), cabin (including gearboxes, motors, controls, etc.) and the tower and Foundation. Wind turbine wheel is the most important part ,which is made up of blades and hubs. Blade has a good aerodynamic shape, which will produce aerodynamic in the airflow rotation, converting wind energy into mechanical energy, and then, driving the generator into electrical energy by gearbox pace. Wind turbine operates in the natural environment, their load wind turbine blades are more complex. Therefore load calculations and strength analysis for wind turbine design is very important. Wind turbine blades are core components of wind turbines, so understanding of their loads and dynamics by which the load on the wind turbine blade design is of great significance.

Modeling wind energy conversion systems is a difficult task that requires the use of a unified language gathering all aspect of energies involved such as kinetic energy, mechanical energy, and electrical energy. Bond Graph methodology is an appropriate tool to analyze wind turbine dynamic behavior since the whole system is modelled in the same frame. Herein, a methodology for HAWT's rotor modeling is proposed based on Bond Graph, aerodynamic laws and Rayleigh Beam theory. It takes into consideration the profile, chord, and twist change along the blade. The model is validated using 20-Sim software and then compared to other models from literature. Simulation results show a better value of power coefficient in comparison with works using the same tools.

The country or region where energy production is based on imported coal or oil will become more self-sufficient by using alternatives such as wind power. Electricity produced by the wind produces no CO2 emissions and therefore does not contribute to the greenhouse effect. Wind energy is relatively labour intensive and thus creates many jobs. Wind energy is the major alternative of conventional energy resources. A wind turbine transforms the kinetic energy in the wind to mechanical energy in a shaft and finally into electrical energy in a generator. The turbine blade is the most important component of any wind turbine. In this article is considered the single airfoil National Advisory Committee for Aeronautics (NACA) 0018 and a computational fluid dynamics (CFD) analysis is done at different blade angles 0º, 10º, 15º, and 30º with a wind velocity of 4 m/s. The analysis results show that a blade angle of 10º gives the best possible power and pressure and velocity distributions are plotted for every case.

Abstract: In the present situation power becomes basic need for human life. Energy is responsible for major developments of any country’s economy. Conventional energy sources generate most of the energy of today’s world. But the population is increasing day by day and the conventional energy sources are diminishing. Moreover, these conventional energy sources are polluting and responsible for global warming. So, nonconventional sources are needed to be developed for power generation which are clean, environment friendly and sustainable. In this research we propose a renewable non-conventional energy source based on speed breaker mechanism. Our project is to enlighten the streets utilizing the jerking pressure which is wasted during the vehicles passes over speed breaker in roadside. We can tap the energy generated by moving vehicles and produce power by using the speed breaker as power generating unit. The kinetic energy of the moving vehicles can be converted into mechanical energy through rack and pinion mechanism and this mechanical energy will be converted to electrical energy using generator which will be used for lighting the street lights. Therefore, by using this mechanism we can save lot of energy which can fulfill our future demands. Keywords: kinetic energy, speed breaker, rack & pinion, generator, non-conventional energy, street light.

Pollution free power production, quick installation and commissioning capability, less operation and maintenance cost and taking benefit of by means of free and renewable energies are all advantages of using wind turbines as an power generators. Along with these advantages, the main drawback of this source is the conditional nature of wind flow. Therefore, using reliable and efficient apparatus is necessary in order to get as much as energy from wind during the limited period of time that it flows strongly. Wind power is the fastest increasing renewable energy resource and wind power penetration in power systems increases at a significant rate. The high access of wind power into power systems in the present and near future will have several impacts on their planning and operation. A wind turbine transforms the kinetic energy in the wind to mechanical energy in a shaft and ultimately into electrical energy in a generator. Turbine blade is the mainly important part of any wind turbine. In this paper we consider single airfoil NACA 0018 and done CFD analysis at different blade angles 00,100,150 and 300 with constant wind velocity of 6 m/s. The analysis results show that blade angle 15º gives best possible power.

<p class="IJOPCMKeywards"><span lang="EN-US">Wind power is dominant energy converted into electricity through wind turbine generators used in wind energy conversion systems. Technological developments produce various types of generators for use in wind power plants of various scales. Permanent magnet generator (PMG) has advantage of being able to produce electrical energy of 500 watts at rotation 600 rotate per minute with an input wind speed of 2.5-12 m/s. The potential for average wind speed throughout the year in Aceh is around 1.5-6.5 m/s cannot be generate electric power because mechanical energy from turbine rotation is not sufficient to meet the minimum demand for RPM generators. The design of a horizontal axis wind turbine (HAWT) with Air Foil Naca 2410 is used to increase the efficiency of the turbine rotation. It’s influenced by variations in the number of blades and material used. Stages of simulation are prioritized to get efficient variations of the number of blades and the most effective material testing is performed. The results showed that variation of the axis of a three-blade wind turbine type has a higher coefficient of power that is 50 percent compared the other, the type of material wind turbines made from pinus more optimal than fiberglass</span><span lang="EN-US">.</span></p>

Continuous Power

Wind power is a domestic source of energy, harnessing a limitless local resource and is a potential source of clean electricity generation. Wind is utilized to create electrical energy by means of the kinetic energy formed by air into movement. This energy is changed to electrical energy by wind speed turbines or also called as wind energy exchange systems. Wind speed power generation creates a progressively more significant position in the method the humans power the world. During the process of wind power generation, a variety of characteristics are to be controlled for efficient working of the system and to avoid failure of continuous power supply. In this project we are aiming to control a few such characteristic such as pitch angle, voltage sag and faults that influence wind power generation. The DC link voltage of the Doubly Fed Induction Generator (DFIG) is also monitored. In this wind turbine system consists of wind turbine, AC generator and controllers are considered. The major purpose of the paper is to find out the mathematical model of the wind turbine, authenticate it by simulation, and devise a suitable controller to present a common aim of outlook regarding the use of this type of clean energy production. Various rudiments are connected collectively and the complete arrangement is modelled and also simulated. The simulation results verify the accuracy of the mathematical models developed and can be utilized for a improved design of systems. Wind turbines make use DFIG which consists of wound rotor type induction generator and a PWM converter of IGBT bases of AC/DC/AC. The stator winding is connected directly to the 60 Hz grid while the rotor is fed at variable frequency through the AC/DC/AC converter. The DFIG machinery permits pulling out highest energy from the wind from lowest wind speeds and optimizing the speed of the turbine there by decreasing mechanical stresses on the turbine during gusts of wind. The most favourable turbine speed producing increased mechanical energy for a given speed of the wind which is directly proportional to the wind speed. The other merit of the DFIG expertise is the capability for the converters of power electronics to produce or take in reactive power, thereby reducing the need for putting in capacitor banks as done for the generators of squirrel-cage induction motor type.
