Blade Geometry Optimization for the Design of Wind Turbine Rotors
This paper describes a blade geometry optimization method for wind turbine rotors in which considerations are given to aerodynamics, structures, noise, and cost. An existing computer program named PROPGA, which is a genetic-algorithm based optimization method for wind turbines, provided part of the foundation for this work. The objective was to develop and implement structures and costs modelin...
متن کامل10 Lidars and wind turbine control – Part 2
Modern utility-scale wind turbines are typically controlled using yaw, generator torque, and blade pitch actuation (Pao and Johnson, 2011). The yaw motor is used to align the rotor with the wind direction for the purpose of maximizing power capture. Generator torque is controlled during below-rated (region 2) operation to maximize power capture by maintaining the optimal tip speed ratio. In abo...

متن کامل9 Lidars and wind turbine control – Part 1
In recent years lidar technology found its way into wind energy. The main application is still the site assessment, but the possibility to optimize the energy production and reduce the loads by nacelle or spinner based lidar systems is becoming an important issue. In terms of control the inflowing wind field is the main disturbance to the wind turbine and most of the wind turbine control is des...
متن کاملWind Turbine Blade Flow Fields and Prospects for Active Aerodynamic Control: Preprint
As wind turbines continue to grow larger, problems associated with adverse aerodynamic loads will grow more critical. Thus, the wind energy technical community has begun to seriously consider the potential of aerodynamic control methodologies for mitigating adverse aerodynamic loading. Spatial and temporal attributes of the structures and processes present in these flow fields hold important im...
