Embodiment Construction

[0028] Wind turbines generate electricity for electrical systems. Typically, many wind turbines are geographically arranged in arrays to more efficiently utilize wind energy. Wind turbines are more efficient when they face directly into the wind direction (wind bearing). As the wind direction changes, the wind turbine may rotate the orientation of the wind turbine (turbine orientation) to face the wind orientation. Accurately determining turbine orientation relative to a known reference orientation (eg, true North) is desirable to increase the efficiency of wind turbines and wind turbine arrays.

[0029] figure 1 One example of a wind turbine array 100 is shown. Array 100 includes a row of wind turbines 102 . Line 104 shows the azimuth line corresponding to the turbine azimuth. The figure above depicts an example of the orientation of the array 100 when the wind direction is perpendicular to the array. When the wind direction is perpendicular to the array, there is no ob...

Abstract

The invention relates to a systems and methods involving wind turbine bearing detection and operation, especially a method for determining a bearing of a wind turbine (200) comprises: receiving a signal (205) from a satellite (203) at a first antenna (208) disposed on a wind turbine (200), receiving the signal (205) from the satellite (203) at a second antenna (210) disposed on the wind turbine(200), determining a position of the first antenna (208) responsive to receiving the signal (205), determining a position of the second antenna (210) responsive to receiving the signal (205), calculating a line of bearing (302) intersecting the position of the first antenna (208) and the position of the second antenna (210), determining an angle of the line of bearing (302) relative to a reference bearing, and defining the bearing of the wind turbine (200) as the angle of the line of bearing (302) relative to the reference bearing.

Description

technical field [0001] The subject matter disclosed herein relates to wind turbines and [0002] A method and system for beaaring direction of a turbine. Background technique [0003] Wind turbines are often used to generate electricity. Wind turbines are most efficient when they face the direction of the wind and the wind is not obstructed. As the direction of the wind changes, wind turbines are designed to rotate to face the wind as the direction of the wind changes. The wind turbines are arranged in a grid pattern designed to efficiently take advantage of the prevailing wind at a given location. Wind turbines rotate as the wind direction changes, but some wind directions can cause obstructions (e.g., natural, man-made, or from other wind turbines in the array), resulting in undesired wind turbulence for specific turbines in the array (wake effect) . If the orientation of the wind turbines is precisely known, the operation of the array can be adjusted to compensate fo...
