摘要:

摘要:齿轮箱是风电机组的主要传动装置,齿轮箱状态监测对保障风电机组安全运行至关重要。风电机组受风速波动影响较大,其转速实时变动,增加了齿轮箱状态监测的难度。通过分析某风电场两台运行机组齿轮箱的振动信号,揭示了齿轮箱振动信号与转速之间的线性关系,提出将任意转速下的振动信号有效值转化到额定转速下的措施,有效降低了转速对振动信号的影响,提高了监测指标的趋势性,可为齿轮箱的状态监测提供有效的监测指标。

Abstract:Gear box is the main actuator for wind turbine unit and its state monitoring is essential for the safety operation of wind turbine unit. Because that wind turbine unit is greatly influenced by wind speed fluctuation, its revolving speed changes in real time, which increases the difficulty of gearbox state monitoring. Through analyzing the gear box vibration signals of two units for a certain wind power plant, this paper revealed the linear relationship between vibration signals and revolving speed. And after that, it proposes the solution of converting the vibration signals under arbitrary speed to rated speed, which effectively reduces the influence of revolving speed to vibration signals, improves the trend of monitoring indictors, and provides effective monitoring indictors for gear box state monitoring.
