不同运行工况下风力发电机塔架的振动响应分析

The Vibration Response of Wind Turbine Structure Under Different Operating Conditions

风机所处环境极为恶劣,受天气影响明显,在环境激励和运行激励作用下,塔架振动形式复杂,振动幅值过大会造成风机塔架损伤,严重时将导致风电事故。通过对风机长期的振动监测,得到实时的结构振动原型监测数据,分析数据得到风机的振动响应特征,为风机结构振动问题提供科学依据,对于避免风电事故的发生具有重要意义。

The wind turbine is operating in harsh environment,which is obviously affected by the weather.The vibration response of wind turbine structure is complex under different operating conditions.If the vibration response is too large,the wind tower structure will be damaged.Through the long-term vibration monitoring,the response data can be obtained,and the vibration response characteristics can be obtained by analyzing the data,so as to provide a scientific basis for the vibration problem of the wind turbine structure,which is of great significance to avoid wind tower accident.
