Abstract
A method of adjusting at least one rotor blade of a wind turbine which includes the steps of receiving a command for adjustment of the rotor blade at an adjustment speed, ascertaining a current moment of inertia of the rotor blade and acceleration of the rotor blade until reaching the adjustment speed, wherein the acceleration until reaching the adjustment speed is limited in dependence on the ascertained moment of inertia. A system and a wind turbine.
Claims20
A method of adjusting a rotor blade of a wind turbine, the method comprising:
- receiving a command for adjusting the rotor blade to an adjustment speed,
- determining a current moment of inertia of the rotor blade, and
- accelerating the rotor blade until reaching the adjustment speed, wherein the accelerating is limited in dependence on the current moment of inertia.
A wind turbine comprising:
- a system configured to:
- receive a command for adjusting a rotor blade to an adjustment speed,
- determine a current moment of inertia of the rotor blade, and
- accelerate the rotor blade until the adjustment speed is reached, wherein the accelerating is limited in dependence on the current moment of inertia,
- a power supply,
- a rotor blade,
- a pitch drive coupled to the rotor blade, and
- a controller, wherein the power supply is configured to supply the pitch drive of the rotor blade, and wherein the controller is configured to determine acceleration of the rotor blade in such a way that a maximum power is not exceeded.
