Abstract
A method for lubricating a bearing, in particular a rotor bearing, of a wind turbine, includes: determining a load condition of a load acting on the bearing, determining an operating condition of the bearing dependent on the determined load condition, determining a damage potential of the bearing dependent on the determined operating condition, providing a lubricant supply signal dependent on the determined damage potential, wherein the lubricant supply signal includes information about supplying lubricant to the bearing.

1-15. (canceled)
A method for lubricating a bearing of a wind turbine, the method comprising:
- determining a load condition of a load acting on the bearing;
- determining an operating condition of the bearing in dependence upon the determined load condition;
- determining a damage potential of the bearing in dependence upon the determined operating condition;
- and,
- providing a lubricant supply signal in dependence upon the determined damage potential, wherein the lubricant supply signal includes information about supplying lubricant to the bearing.
A lubricant supply system for a wind turbine, the lubricant supply system comprising:
- a control unit including a processor and a non-transitory computer readable storage medium having program code stored thereon;
- a lubricant supply device;
- said control unit being configured to control said lubricant supply device;
- said program code being configured, when executed by said processor, to:
- determine a load condition of a load acting on a bearing;
- determine an operating condition of the bearing in dependence upon the determined load condition;
- determine a damage potential of the bearing in dependence upon the determined operating condition;
- and,
- provide a lubricant supply signal in dependence upon the determined damage potential, wherein the lubricant supply signal includes information about supplying lubricant to the bearing.
A wind turbine comprising:
- a bearing;
- a lubricant supply system coupled with said bearing to supply lubricant to said bearing;
- said lubricant supply system having a lubricant supply device and a control unit including a processor and a non-transitory computer readable storage medium having program code stored thereon;
- said control unit being configured to control said lubricant supply device;
- said program code being configured, when executed by said processor, to:
- determine a load condition of a load acting on said bearing;
- determine an operating condition of said bearing in dependence upon the determined load condition;
- determine a damage potential of said bearing in dependence upon the determined operating condition;
- and,
- provide a lubricant supply signal in dependence upon the determined damage potential, wherein the lubricant supply signal includes information about supplying lubricant to said bearing.
