This wind farm is located in a mountainous area at an altitude of over 2,000 meters and has 80 wind turbines with a single-unit capacity of 3 MW, each with blades 68 meters long. Traditional manual inspections require workers to climb to the top of the turbines, taking about 2 hours to inspect each turbine, with a risk of falling from heights. After introducing drone inspections, drones equipped with high-definition zoom cameras and ultrasonic flaw detectors can complete a comprehensive inspection of a single turbine blade within 15 minutes.

Using the high-resolution images and flaw detection data captured, minor cracks and coating defects on the blade surface can be accurately identified. In 2023, the wind farm discovered a total of 23 blade damages through drone inspections, enabling timely repairs and preventing shutdown accidents caused by blade failures. Each turbine reduced downtime by about 120 hours per year, increased power generation by approximately 360,000 kWh, and enhanced annual economic benefits by over 2 million yuan.
