Effectiveness of Plasma Actuator on the Performance of a Wind Turbine: An Aeroelastic Simulation

DOI

説明

Large wind turbines can experience significant vertical and horizontal shear and varying turbulence over blades span.Since, both these factors may result in flow separation over blades, active flow control devices such as plasma actuators(PA) have been receiving interest as they may alleviate the loadings on blades and maintain turbine efficiency. The current study investigates the overall effect of PA on the control response and performance of a wind turbine. To that end, aero-servo-elastic simulations with and without PA are performed for a 300 kW wind turbine for both steady and uniform, and turbulent inflow conditions. The effect of PA is implemented as lift and drag coefficients which were obtained from separate wind tunnel experiments. It is found that control parameters (rotor speeds and blade pitch angles) have no effect of PA and responses with and without PA overlapped in both steady and uniform, and turbulent cases. Similarly, thrust forces and power outputs as well as their fluctuations showed similar characteristic for the simulations with and without PA. Further analysis shows that the turbine mostly operated around the angle of attacks which are below the stall angles of the airfoils. Since PA is not effective at such lower angle of attack the difference between results with and without PA is negligible.
