风电齿轮箱润滑状态监测与故障诊断系统开发

Monitoring on lubrication condition of wind power gearbox and development of fault diagnosis system

齿轮箱是风电机组关键的子系统,其润滑系统的智能控制和管理是延长其使用寿命的重要因素。采用灰色理论对润滑监控参数进行预测,实现对齿轮箱润滑状态的实时监测和预判,采用故障树模型对润滑系统的故障进行诊断,提高诊断的效率和准确率。

Gearbox is the key subsystem of a wind power unit,and the intelligent control and management is a key to prolong service life of lubrication system. It forecasts lubrication monitoring parameters by taking the Grey theory,which achieves the real-time monitoring and prediction on gearbox lubrication condition. Fault tree model is used to diagnose the fault in lubricating system,which can improves the efficiency and accuracy of diagnosis.
