All over the world, energy companies are investing in technologies to make better use of renewable energy to generate electric power. Wind energy is the renewable energy source that had a higher growing in the last decades and can be considered a hope in future based on clean and sustainable energy. The development of tools that allows operators and maintenance personnel to correlate machinery related...
In this paper, a functional structure of a wind energy conversion system is introduced, before making a comparison between the two typical wind turbine operating schemes in operation, namely constant-speed wind turbine and variable-speed wind turbine. In addition, the modeling and dynamic behavior of a variable speed wind turbine with pitch control capability is explained in detail and the turbine...
The operation and management of a wind turbine power plant are not significantly different from that for a traditional power station, yet offers unique challenges. The lessons-learned from successful management of traditional power plants are just as applicable to this technology and will ultimately improve the safety, reliability, and investment returns of the wind power facility. This paper will...
This paper proposes a new solution for wind electrical energy generating system (WEEGS). The system here taken into account is moved by a modular multiple blade fixed pitch wind turbine (MMBFPWT) and foresees a new MPPT algorithm whose main characteristics are low cost, low noise, buildings simplicity and modularity. The mathematical model of the entire WEEGS has been here developed taking into account...
Because of energy shortage and environment pollution, the renewable energy, especially wind energy has become more and more considerable all over the world. Vertical-axis wind turbine (VAWT) has some advantages. The heavy parts such as gearbox, generator and control system can be placed on the ground and they can be maintained easily. The head of horizontal-axis wind turbines (HAWT) must be rotated...
The report describes the design criteria for high efficiency small-scale wind turbines. While the overall wind to electrical conversion efficiency for large diameter rotors can be set at around 50%, the design of conventional wind turbines with diameters below 0,5 m is limited by air turbulence and low electrical efficiency. Coupling a ring shaped generator with ducted blades an overall efficiency...
The global electrical energy consumption is still rising and there is a steady demand to increase the power capacity. The production, distribution and the use of the energy should be as technological efficient as possible and incentives to save energy at the end-user should be set up. The deregulation of energy has lowered the investment in larger power plants, which means the need for new electrical...
This paper deals with the design, analysis and simulation of wind turbine associated with a storage unit to generate a constant active power through the grid for all wind conditions. Variable speed wind turbine with a doubly fed induction generator which allows a large speed variation and so a large range of wind is employed. Associated with an inverter controlled with power reference, it is possible...
