Suggestion of temporarily for forecast diagnosis on blade of small wind turbine

Abstract

The development of a fault diagnosis system for small wind turbines is necessary; recently, the system of wind-generated power has continued to become outdated, and there have been many cases of damages to the blades of small wind turbines and to the internal areas of the generator due to flying objects and lighting. The early failure diagnostic system of the small wind turbine using impact sensor was proposed, and the failure level was discovered. When the damage at 20 mm exceeded the change of a shock wave, it turned out that the waveform change notably appeared.
