Abstract:

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.

Key words:
