Abstract
A method for monitoring the condition of oil contained within a gearbox of a wind turbine is disclosed. The method generally includes receiving a signal corresponding to a measurement of an oil parameter of the gearbox, comparing the measurement to a predetermined limit for the oil parameter, assigning a severity level based on the comparison of the measurement to the predetermined limit and determining a recommended course of action for the wind turbine based on the severity level.
Claims20
A method for monitoring the condition of oil contained within a gearbox of a wind turbine, the method comprising:
- receiving a signal corresponding to a measurement of an oil parameter of the gearbox;
- comparing the measurement to a predetermined limit for the oil parameter;
- in the event that the measurement exceeds the predetermined limit, assigning a severity level to the measurement based on the extent to which the measurement exceeds the predetermined limit;
- and,
- implementing a predetermined logic sequence for the assigned severity level.
A method for monitoring the condition of oil contained within a gearbox of a wind turbine, the method comprising:
- receiving signals corresponding to a plurality of measurements of an oil parameter of the gearbox;
- determining a time measurement of a service interval of the gearbox;
- comparing the time measurement to a predetermined time limit;
- and,
- in the event that the time measurement exceeds the predetermined time limit, determining a recommended course of action based on analysis of the plurality of measurements.
