Nondestructive testing method for blade defects of wind turbine generator
Wind power has potential to become an important part of future energy structure. But the fan blades often have defects and damage. At present, non-destructive testing methods used for fan blade defects include Portable Digital Radiography Systems, ultrasonics, acoustic emission, fiber optic sensors, and infrared thermal imaging detection technologies. However, each NDT equipment has its own advantages and limitations, and there is no perfect standard to specify the applicable stage of the detection method.
