How Wind Power Works

The two primary aerodynamic forces at work in wind-turbine rotors are lift, which acts perpendicular to the direction of wind flow; and drag, which acts parallel to the direction of wind flow. Turbine blades are shaped a lot like airplane wings -

6 FAQs about [Wind turbine blade direction control]

How do you control a wind turbine?

You can control a turbine by controlling the generator speed, blade angle adjustment, and rotation of the entire wind turbine. Blade angle adjustment and turbine rotation are also known as pitch and yaw control, respectively. A visual representation of pitch and yaw adjustment is shown in Figures 5 and 6. Figure 5: Pitch adjustment.

How can a vertical axis turbine be controlled?

Alternative strategies at the turbine level to control the performance of vertical-axis turbines are intracycle control of the turbine’s rotational velocity 12, 38 or blade pitching 11, 25, 39. These two strategies modify the unsteady blade kinematics within one turbine rotation with the goal to control the overall turbine power.

What is pitch control in a wind turbine?

The purpose of pitch control is to maintain the optimum blade angle to achieve certain rotor speeds or power output. You can use pitch adjustment to stall and furl, two methods of pitch control. By stalling a wind turbine, you increase the angle of attack, which causes the flat side of the blade to face further into the wind.

How do wind turbine blades work?

Furling decreases the angle of attack, causing the edge of the blade to face the oncoming wind. Pitch angle adjustment is the most effective way to limit output power by changing aerodynamic force on the blade at high wind speeds. Yaw refers to the rotation of the entire wind turbine in the horizontal axis.

What are the three types of control techniques for wind turbine rotors?

In this paper, state-of-the-art control techniques for wind turbine rotors adopted by researchers are viewed and categorized according to the three types of controllers for WTs: pitch control, yaw control, and torque control. 2. Pitch Control Technique

What are wind turbine control systems?

However, wind turbine control systems are important factors in determining the efficiency and cost-effectiveness of a wind turbine (WT) system for wind applications. As wind turbines become more flexible and larger, it is difficult to develop a control algorithm that guarantees both efficiency and reliability as these are conflicting objectives.
