Abstract
The present disclosure relates to methods (100, 200) for estimating an actual value of an operational parameter (67) of a wind turbine (10). A method (100) comprises determining (120) which sensors of a plurality of sensors (61) of the wind turbine (10) are reliable and which sensors of the plurality of sensors (61) are unreliable. The method (100) further comprises estimating (130) the actual value of the operational parameter (67) based on a mathematical model and on data related to the operational parameter (63) measured by the reliable sensors.

1-15. (canceled)
A method for estimating an actual value of an operational parameter of a wind turbine, the method comprising:
- receiving data related to the operational parameter from a plurality of sensors in the wind turbine;
- from the received data, determining which of the plurality of sensors are reliable sensors and which of the plurality of sensors are unreliable sensors;
- and
- estimating the actual value of the operational parameter based on a mathematical model and on the data related to the operational parameter received from the reliable sensors.
A wind turbine controller comprising a processor and a memory, wherein the memory comprises instructions that, when executed by the processor, cause the processor to:
- receive data related to the operational parameter from a plurality of sensors in the wind turbine;
- from the received data, determine which of the plurality of sensors are reliable sensors and which of the plurality of sensors are unreliable sensors;
- and
- estimate the actual value of the operational parameter based on a mathematical model and on the data related to the operational parameter received from the reliable sensors.
A method for estimating a value of an operational parameter of a wind turbine, the method comprising:
- measuring data related to the operational parameter with a plurality of wind turbine sensors;
- determining which of the plurality of sensors are reliable sensors and which of the sensors are faulty or excessively noisy sensors;
- performing an initial estimation of the actual value of the operational parameter with a mathematical model;
- and
- correcting the initial estimation with data directly indicative of the operational parameter based on measurements by the reliable sensors.
