In this report, response acceleration of the tower section of an existing wind power generation facility was continuously measured. Vibration models were constructed from these results, and the vibration control effects of single TMD and multiple TMDs were verified for each of the following cases: at standstill, at annual average wind speed, and at rated wind speed. The RMS values of response acceleration and displacement were reduced by about 15% and more than 50%, respectively, at the most frequent annual average wind speed, confirming the vibration reduction effect of the multiple TMDs.
