Description

technical field [0001] The invention relates to the technical field of wind power generation measurement and control, in particular to a method and system for monitoring the running track of blades of a wind power generating set. Background technique [0002] With the development of science and technology, material technology has been updated day by day, thus promoting the rapid development of wind power generation technology, and wind power generation technology is becoming more and more mature. Although the wind resources are unlimited, the land resources available for installation are limited, so wind turbine towers are getting taller and wind turbine blades are getting longer and longer. In the industry, large-scale wind turbines refer to wind turbines with a power greater than 600kW. [0003] The wind farm environment is usually very harsh, and the working conditions of wind turbines are complex and changeable, which makes wind turbines prone to failure. The cost of w...
