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.

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.

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.

Input source for wind power generation in wind turbine is wind. Variation of wind is uncontrolled. Quality of power gener- ated in a windmill is very poor due to uncontrolled and fluctuated nature wind. As per International Electro-technical Commission standard, IEC-61400 norms the power quality and measurements of wind turbine is to be calculate. Electrical energy generated from wind power is based on minimum pollution of environment as comparative to conventional sources of generation. In a grid connected wind power system there are some power quality issues. In grid integrated wind power systems, quality of power is measured by active power, reactive power & variation of voltages measured under guidelines of national & international standards. In this proposed system, the energy generated by wind turbine is converted to DC & DC bus is charged. A microcontroller regulated PWM inverter convert this DC voltage to AC to feed it to grid. The pro- posed DC Bus is augmented by PV (photovoltaic) charged Battery Based PWM controlled STATCOM.

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.

Although mega-watt class onshore and offshore wind power systems are used to generate power due to their cost-effectiveness, small wind power systems are important for household usages. Researchers have focused on aerodynamic characteristics as a conceptual design from their previous studies on Archimedes spiral wind turbines. Here, we verified the design of a small wind turbine AWM-750D (100 W capacity) via both numerical simulation and experimentation. We used commercial code ANSYS CFX for numerical simulation and compared turbulence models and surface roughness for determining the performance. To obtain reliable and robust blades, we analyzed the effective manufacturing method with Moldflow. Through a test with an open-suction type atmospheric boundary layer wind tunnel, we varied wind speed from 4.0 m/s to the rated value of 12.5 m/s and obtained 106 W, equivalent to a power coefficient of 0.205. In addition, we compared the numerical and experimental power vs. rotational speed and found the former is 6.5% lower than the latter. In this study, we proved that numerical simulations can act as design verification methods to predict wind turbine performances and reliable manufacturing. Through our research, we provided the prototype of a small wind turbine with 100 W to act as an efficient electric power supplier for households and also the stable manufacturing process for complex spiral blades using injection molding.
