Individual Pitch Regulation for Wind Turbine

Abstract:

Article Preview

In order to reduce the tilt moment and yaw moment caused by asymmetric wind, aerodynamic model for individual pitch control of large-scale wind turbines was established. Because the aerodynamic model have characteristics of multiple variables, strong coupling and time-varying, First, it was converted into a linear time-invariant and non-coupled model utilizing a coordinate transformation, and so the controller design was simplified. Finally, take wind shearing as a disturbance and designed two independent PID controllers, simulated a 1.5MW wind turbines. The results show that individual pitch control greatly reduced the moment and yaw moment of wind turbine.
