A sensor system for a wind turbine blade, the system comprising: a blade load sensor providing a load measurement; a processing unit interfaced with the blade load sensor and configured to provide a corrected load parameter as an output. The processing unit includes: an axial force estimation module that determines an estimated axial force on the wind turbine blade in a direction along the length of the blade; and a load calculation module that 10 determines the corrected load parameter based on the estimated axial force and the load measurement of the blade load sensor.

Blade load sensing system for a wind turbine

For optimising annual energy production in a wind turbine, the invention provides a method by which operation of the turbine in accordance with different pre-specified modes depending on the wind direction towards the turbine is enabled. The modes may include pitch and/or power control strategies. The invention further provides a control system for a wind turbine adapted to operate in accordance with the method, and a wind turbine with such a control system.
