Abstract

The invention relates to a surface defect detection system for a wind turbine generator vane, and a detection method, and belongs to the field of wind power fault detection. The system comprises an imaging array device used for identifying defects, a positioning array device, an image processing server, an array control device, a communication cable and an alternating current power supply, wherein the positioning array device is used for positioning whether a whole visual field range is full of the vane and is used for assisting in regulating the shooting angle of the imaging array device; the imaging array device is connected with the positioning array device; the image processing server is connected with the array control device; and the positioning array device and the array control device are both connected with the alternating current power supply through the communication cable.

Description

technical field [0001] The invention relates to a detection system and a detection method for a surface defect of a wind turbine blade, belonging to the field of wind power failure detection. Background technique [0002] In recent years, the annual growth rate of global renewable energy utilization has reached 25%. The use of renewable energy will be dominated by the power sector, and the share of electricity generation from non-hydro renewable energy renewable energy sources will triple. According to statistics, the consumption of renewable energy in 2030 will exceed 2.2 billion tons of oil equivalent. Wind power generation is the most mature renewable energy power generation except for hydropower, and its installed capacity accounts for the vast majority of the total installed capacity of renewable energy power generation. However, the limitation of the performance of power electronic devices has caused a certain bottleneck to the development and application of large-ca...
