风电技术迅猛发展，风电场风力机故障频发，对风机的安全运行和故障诊断的研究已成为风电技术发展中的重要研究内容。国内对于风力机故障诊断技术的研究尚在起步阶段，且集中于对齿轮箱的研究，对转子不对中故障研究尚少。针对以上问题，用振动测试系统对异常工作风力发电机组进行振动测试，采集振动测试信号，对振动信号进行时域、频域分析，得到机组转子不对中故障信号特征，为风力机转子不对中故障诊断提供依据。
風電技術迅猛髮展，風電場風力機故障頻髮，對風機的安全運行和故障診斷的研究已成為風電技術髮展中的重要研究內容。國內對于風力機故障診斷技術的研究尚在起步階段，且集中于對齒輪箱的研究，對轉子不對中故障研究尚少。針對以上問題，用振動測試繫統對異常工作風力髮電機組進行振動測試，採集振動測試信號，對振動信號進行時域、頻域分析，得到機組轉子不對中故障信號特徵，為風力機轉子不對中故障診斷提供依據。

With the rapid development of wind power technology, faults of windmill generators happen frequently. Research of safe operation and fault diagnosis for the windmill generators has become an important topic. The domestic research of fault diagnosis technology of windmill generators is still in the initial stage and only focused on gearboxes. But researches of rotor misalignment fault diagnosis are few. In this paper, the vibration signal of the windmill generators in abnormal operation was collected by a vibration test system, and the rotor misalignment fault signal was detected by analyzing the vibration signal in both time-domain and frequency-domain. This work provides a reference for fault diagnosis of rotor misalignment.
