Site Measurement, Wind Tunnel Test and Numerical Simulation of the Aerodynamic Load Acting on Wind Turbine Generator

Effect of Wind Speed and Load Correlation on ELCC of Wind Turbine Generator

Utilization of wind turbines as economic and green production units, poses new challenges to the power system planners, mainly due to the stochastic nature of the wind, adding a new source of uncertainty to the power system. Different types of distribution and correlation between this random variable and the system load makes conventional method inappropriate for modeling such a correlation. In...

Design of a Wind Tunnel Scale Model of an Adaptive Wind Turbine Blade for Active Aerodynamic Load Control Experiments

Within wind energy research there is a drive towards the development of a “smart rotor”; a rotor of which the loading can be measured and controlled through the application of a sensor system, a control system and an aerodynamic device. Most promising solutions from an aerodynamic point of view are trailing edge flaps, either hinged or continuously deformable. An experiment was considered neces...

Aerodynamic design and economical evaluation of site specific horizontal axis wind turbine (HAWT)

This paper presents the aerodynamic design and economical evaluation of a 200 kW site specific wind turbine for the province of Semnan in Iran. By designing site specific wind turbines, the cost of energy which is calculated out of the annual energy production and also the cost of manufacturing the rotor are minimized. The aerodynamic design is based on the well-known blade element momentum...

Aerodynamic Analysis and Wind Tunnel Test for Flapping-wing Mavs

A lightweight flapping-wing micro air vehicle (MAV) was designed and built and successfully filed in the sky. The unsteady aerodynamics associated with this MAV was detailedly studied by using the method of computational fluid dynamics (CFD).The variations of different parameters of the flapping MAV, such as flapping amplitude, pitch amplitude and flapping frequency, were investigated with nume...
