Embodiment Construction

[0027] The examples of the present invention will now be described in detail, and examples of the embodiments are illustrated in the drawings, wherein the same reference numerals always refer to the same components. The embodiment will be described below to explain the embodiments to explain the invention.

[0028] figure 1 A flow chart showing a gust detection method according to an exemplary embodiment of the present invention.

[0029] Refer figure 1 In step S110, it is determined that the thrust from the wind turbine is.

[0030] As an unlimited example, the thrust of the wind turbine can indicate the thrust in a direction perpendicular to the plane of the blade. However, the present invention is not limited thereto, and the direction of the thrust of the wind turbine can be predetermined as a force in other directions. Further, in the present invention, the thrust of the wind turbine can be determined periodically or unmetly.

[0031] Here, the thrust from the wind turbine c...

Abstract

The invention provides a gust detection method, a gust controller and a wind power generation system. The gust detection method comprises the steps that the thrust borne by a wind turbine is determined; the speed of a tower of the wind turbine in the forward-and-backward direction is determined; the acceleration of the tower of the wind turbine in the forward-and-backward direction is determined; the gust intensity is calculated on the basis of the thrust, the speed, and the acceleration; the calculated gust intensity is compared with a predetermined threshold value, so that whether a gust exists is detected.

Description

Technical field [0001] The present invention relates to the field of wind power, and more particularly to a gust detecting method, a gust controller, and a wind power system. Background technique [0002] The presence or absence of a gust usually affects the performance of the wind power system. Therefore, the detection of the gust is very important to the wind power generation system. [0003] The existing gust detection method typically uses laser radar to measure the wind speed in front of the wind turbine to detect its gust before the wind turbine is hitting the wind turbine. However, laser radar tends to cost the price, making the detection of the cost of the gust of gusts. Inventive content [0004] An exemplary embodiment of the invention is to provide a gust detecting method, a gust of wind controller, and a wind power generation system. [0005] According to an exemplary embodiment of the present invention, there is provided a gust detecting method including: determinin...
