The amount of electricity produced from the windhas steadily grown since its introduction in the 1980s. Through support from the United States National Science Foundation (NSF) and specifically via the Network for Earthquake Engineering Simulation (NEES), a multiyear investigation into the seismic behavior or wind turbines is underway at the University of California at San Diego (UCSD). Building on the UCSD NEES shake-table test, the experimentation has explored the seismic response of an actural 65 kW turbine, standing over 80 feet tall, when subjected to strong earthquake motions. The NEES UCSD outdoor shake-table facility is the only location in the world that is capable of testing a full scale wind turbine. During the test, various types of sensors such as accelerometers, strain gages, displacement gages, and wired/wireless fiber Bragg grating (FBG) sensors on the wind turbine structure. This paper presents brief introduction to the test, wired/wireless FBG sensor system, measured data by FBG sensors, and signal processing results. Up to now it is on-going project, and detailed signal analysis is under investigation with UCSD. |
