Embodiment Construction

[0039] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0040] figure 1 A flowchart showing a method for monitoring blade icing of a wind power generator according to an exemplary embodiment of the present invention.

[0041] refer to figure 1 , in step S10, the image of the blade is captured by the camera.

[0042] As an example, images of the blade may be taken periodically by the camera.

[0043] As an example, the camera may be mounted on the nacelle of the wind turbine. As another example, the camera can take a clear image under conditions of low brightness (for example, at night) through an infrared supplementary light.

[0044] In step S20, the area where the blade is located is detected from the captured image. ...

Abstract

Provided are a method and an apparatus for monitoring icing of wind turbine blades. The method comprises the following steps of: photographing an image of a blade through a camera; detecting an area where the blade is located from the captured image; removing image information of a background area other than the area where the blade is located from the photographed image to obtain a blade image; the obtained leaf image being input to a leaf icing identification model trained based on a sample set including a plurality of leaf images indicative of the leaf icing to determine whether the photographed leaf is iced. According to the method and the device, whether the blade of the wind turbine freezes or not can be quickly and accurately monitored.

Description

technical field [0001] The present invention generally relates to the field of wind power generation, and more specifically relates to a method and device for monitoring icing of blades of a wind power generator. Background technique [0002] In view of the negative impact of fossil fuel consumption on the ecological environment, renewable energy has attracted much attention in recent years, and it is the general trend to replace traditional energy with new clean energy. With the wide application of new energy technology and the rapid development of wind energy technology, the installed capacity of wind power generators continues to hit new highs. Due to its short construction period and high power generation efficiency, it has been favored by more and more people. Wind power has become my country's new energy power generation. main force. The development and utilization of renewable clean energy resources such as wind energy is in line with the trajectory of energy developm...
