Title:
SYSTEM AND METHOD FOR MONITORING GREASE OF WIND POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2018/207464
Kind Code:
A1
Abstract:
The present invention carries out steady monitoring and predictive diagnosis of grease used for important rotating components (bearings) of a wind power generator, such as the main shaft, generator, yaw bearing, and pitch bearing. The present invention is a system for monitoring grease supplied to a mechanical drive unit of a wind power generator. This system is provided with a server, or the like, essentially comprising an input device, processing device, storage device, and output device. The input device receives measurement data obtained from an optical sensor disposed in at least a part of a grease route and receives an operation parameter for the wind power generator. The processing device generates a physical parameter for the grease from the measurement data. The storage device stores the physical parameter as a time series. The processing device predicts a future physical parameter on the basis of the physical parameter time series and the operation parameter.
