SOURCE LOCATION METHOD FOR GFRP WIND TURBINE BLADE USING ACOUSTIC EMISSION SIGNAL MAPPING

摘要

Recent social issues related to energy crisis and environmental pollution caused a concern for the renewable energy sources. One of the promising future energy, wind energy is taking its place as an alternative energy and the market of wind turbine system is growing steadily. Moreover wind turbine blades are getting large in size due to the demands of high power wind turbine application. As wind turbine blades increase in size, there is an increasing need to monitor the health of the structures.
