A method for predicting a wind turbine oil filter wear level wherein a differential pressure exists between upstream and downstream sides of the filter. The method includes extracting features from wind turbine sensor data to provide extracted data and selecting features from the extracted data that correlate with a change in the differential pressure. The method also includes estimating a filter condition by learning a filter regressive linear model that uses filter direct environment operating conditions data obtained from the extracted data. In addition, the method includes forecasting at least one operating condition scenario represented by three features obtained from the extracted data. Further, the method includes forecasting a filter wear level wherein the filter model uses the at least one forecasted operating condition scenario represented by the three features.

Systems, methods, and computer-program products for fluid analysis and monitoring are disclosed. Embodiments include a removable and replaceable sampling system and an analytical system connected to the sampling system. A fluid may be routed through the sampling system and data may be collected from the fluid via the sampling system. The sampling system may process and transmit the data to the analytical system.

A temperature of an oil pump unit is estimated to operate an electric oil pump to supply a hydraulic pressure to a transmission, based on the required hydraulic pressure and driving status information. An output torque is then adjusted based on the estimated temperature.
