Abstract
A method of controlling a wind turbine is provided, comprising identifying an out-of-vertical load acting in a first direction on the wind turbine. A direction of a wind load acting on the wind turbine is determined. If there is a degree of alignment between the direction of the wind load and the first direction, the wind turbine is controlled to reduce the wind load.
Claims20
A method of controlling a wind turbine comprising:
- identifying an out-of-vertical load acting in a first direction on the wind turbine;
- determining a direction of a wind load acting on the wind turbine;
- determining whether there is a degree of alignment between the direction of the wind load and the first direction;
- and
- when there is a degree of alignment between the direction of the wind load and the first direction, controlling the wind turbine to reduce the wind load, and
- wherein the out-of-vertical load comprises a solar-induced out-of-vertical load caused by solar radiation heating of the wind turbine.
3 more elements
A wind turbine control system comprising:
- a wind load block configured to determine a wind load acting on a wind turbine;
- and a controller configured to receive the wind load from the wind load block;
- wherein the controller is configured to control the wind turbine in accordance with an operation, comprising:
- identifying an out-of-vertical load acting in a first direction on the wind turbine;
- determining a direction of a wind load acting on the wind turbine;
- determining whether there is a degree of alignment between the direction of the wind load and the first direction;
- and
- when there is a degree of alignment between the direction of the wind load and the first direction, controlling the wind turbine to reduce the wind load, and
- wherein the out-of-vertical load comprises a solar-induced out-of-vertical load caused by solar radiation heating of the wind turbine.

A wind turbine, comprising:
- a tower;
- a nacelle disposed on the tower, the nacelle housing a generator;
- a rotor mechanically coupled to the generator;
- a plurality of blades coupled to a distal end of the rotor;
- and
- a wind turbine control system configured to perform an operation, comprising:
- identifying an out-of-vertical load acting in a first direction on the wind turbine;
- determining a direction of a wind load acting on the wind turbine;
- determining whether there is a degree of alignment between the direction of the wind load and the first direction;
- and
- when there is a degree of alignment between the direction of the wind load and the first direction, controlling the wind turbine to reduce the wind load, and
- wherein the out-of-vertical load comprises a solar-induced out-of-vertical load caused by solar radiation heating of the wind turbine.
