Modelling and power regulation of horizontal variable speed wind turbines
This paper deals with the development of a nonlinear model of a horizontal variable speed wind turbine, the obtaining of an appropriate linear model and the design and analysis of a linear quadratic controller with disturbance estimation. The optimisation criteria will have to define an acceptable compromise between the limitations of the power level in the above rated wind speeds and the maint...

متن کاملA comparison between the dynamics of horizontal and vertical axis offshore floating wind turbines.
The need to further exploit offshore wind resources in deeper waters has led to a re-emerging interest in vertical axis wind turbines (VAWTs) for floating foundation applications. However, there has been little effort to systematically compare VAWTs to the more conventional horizontal axis wind turbine (HAWT). This article initiates this comparison based on prime principles, focusing on the tur...
متن کاملPower curves for wind turbines
The concept of a power curve is introduced, as well as the principles of the power conversion performed by a wind turbine. As an appropriate approach for the estimation of the annual power production of a wind turbine, the procedure to determine the power curve after the international standard IEC 61400 of the International Electrotechnical Commission (IEC) is discussed. As another approach is ...
متن کاملSimulation of Vertical Axis Wind Turbines With Variable Pitch Foils
A dynamic computer model of a turbine was developed in MATLAB in order to study the behavior of vertical axis wind turbines (VAWTs) with variable pitch (articulating) foils. The simulation results corroborated the findings of several empirical studies on VAWTs. The model was used to analyze theories of pitch articulation and to inform the discussion on turbine design. Simulations of various mod...
