Abstract

The invention provides a wind turbine generator blade icing detection method, device and system and a storage medium, and belongs to the technical field of wind power generation. The detection method comprises the following steps of acquiring image information of a whole fan blade or a specific area, wherein the image information comprises a red mark; the red mark is pre-marked on the fan blade; reading the characteristic value of the red mark in the image information; the characteristic value of the red identifier comprises one or more of the brightness, ambiguity and RGB value of the red identifier in the image information; and according to the characteristic value of the red identifier, judging the freezing state of a current fan blade. Based on a computer image processing technology, the characteristic value of the red mark is identified from the image information, and the current freezing state of the fan blade is judged. According to the detection method, judgment of the freezing degree of the fan blade is more visual, and it is avoided that due to the fact that inherent operation parameters or environment parameters of a fan or the fan blade are adopted, judgment of the freezing degree of the fan blade is inaccurate.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a method, device, system and storage medium for detecting icing of blades of a wind turbine. Background technique [0002] Wind energy is a clean and renewable energy, and wind power generation is the process of converting wind energy into electrical energy. Northeast China, North China, and Northwest China are rich in wind energy resources, which are very conducive to wind power generation. However, the lowest winter temperature in these places is lower than -20°C, and the critical rain, snow, fog, dew, etc. are easy to freeze on the surface of the fan blades. Icing on the surface of fan blades changes the aerodynamic shape of the blades, thereby reducing the wind energy utilization coefficient and output. In severe cases, the unit cannot be started, and the fatigue of the unit components is increased due to the unbalanced ice load, causing many proble...
