Abstract
An azimuth angle measurement system includes a rotatable ring, a wire coupled at a first end to the ring, a length measurement device configured to measure a length of a portion of the wire that extends from the ring, and a control system configured to determine an azimuth angle based on the length of the portion of the wire extending from the ring.
Claims20
An azimuth angle measurement system, comprising:
- a rotatable ring;
- a wire coupled at a first end to said ring;
- a length measurement device configured to measure a length of a portion of said wire that extends from said ring;
- and,
- a control system configured to determine an azimuth angle based on the length of the portion of said wire extending from said ring.
A wind turbine, comprising:
- a tower;
- a nacelle rotatable with respect to the tower;
- and,
- an azimuth angle measurement system comprising:
- a ring coupled to said nacelle and configured to rotate with said nacelle;
- a wire coupled at a first end to said ring;
- a length measurement device coupled with respect to said wire, said length measurement device configured to measure a length of a portion of said wire that extends from said ring;
- and,
- a control system configured to determine an azimuth angle based on the length of the portion of said wire extending from said ring.
A method for measuring an azimuth angle of a wind turbine using an azimuth angle measurement system including a wire coupled to a nacelle of the wind turbine, a plumb coupled to the wire, and a length measurement device coupled with respect to the wire to measure a position of the plumb, said method comprising:
- measuring a displacement of the plumb from an initial position using the length measurement device;
- determining the azimuth angle based on the displacement of the plumb;
- and,
- outputting the determined azimuth angle.
