Abstract A synchronous monitoring system for vibration acceleration of a wind driven generator, hat of its pylon, and a wind wheel wake was constructed using the devices of PULSE19 and TR-PIV. The vibration features and turbulent vortex near blade tip of a 1.4m-diameter horizontal axis wind turbine were measured and analyzed, it was shown that there is a close relation between wind wheel vibration and wake; the energy of the first harmonic vibration component caused due to the wind wheel rotating is the highest. Comparing frequency spectra of wind wheel’s vibration acceleration and wake, it was found that the characteristic frequency of acceleration peak and that of wake energy peak are very close，so the wind wheel vibration energy is transmitted into the flow field; after the wind turbine has a yaw, the energy transfer between the third harmonic vibration component due to wind wheel rotating and the first harmonic component of the wake is blocked; when yaw angle is less than 10°, the wake energy value is more sensitive to the change of wind wheel vibration acceleration; with increase in yaw angle, the relevance between them decreases.
