You can use different control methods to either optimize or limit power output. 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.

the turbine hub and blades. As wind strikes the turbine’s blades, the hub rotates due to aerodynamic forces. This ro-tation is then sent through the transmission system to de-crease the revolutions per minute. The transmission system consists of the main bearing, high-speed shaft, gearbox, and low-speed shaft. The ratio of the gearbox .

6 FAQs about [What to do if the wind turbine blades lose 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.

Why do wind turbine blades fail?

Abstract – A review of the root causes and mechanisms of damage and failure to wind turbine blades is presented in this paper. In particular, the mechanisms of leading edge erosion, adhesive joint degradation, trailing edge failure, buckling and blade collapse phenomena are considered.

How do you stall a wind turbine?

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. Furling decreases the angle of attack, causing the edge of the blade to face the oncoming wind.

How to improve the safety of a wind turbine?

Besides, during an extreme disaster, e.g. earthquake or hurricane, the natural frequency of wind turbine will shift a little bit, which may invalidate some classical controls. Many solutions are developed to improve the safety of wind turbine such as deploying a robust control, deploying multi-directional dampers.

How to control wind turbine pitch?

Individual pitch control is an effective way to control fatigue loads and prolong the lifetime of wind turbines. Control of blade pitch and generator revolutions per minute (RPM) for protection against excessive stresses is another effective method.

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.
