Abstract: With the rapid development of wind power technology, faults of wind turbine happened frequently. The research on the safe operation and the fault diagnosis of the wind turbine has become an important content in wind power technology development. The domestic research on the fault diagnosis technology of wind turbine is still in the initial stage and focus on the gear box a few in rotor misalignment fault. In view of these problems, the acquisition of vibration signal on the abnormal operation wind turbines was completed by the vibration test system and rotor misalignment fault signal was detected by analyzing the vibration signal in time domain and frequency domain. It will make contribution to rotor misalignment fault diagnosis.
