    Abstract: A method of measuring load on a wind turbine, and a wind turbine for such load measuring, are disclosed. The wind turbine comprises at least one rotor blade and at least one load sensor associated with the rotor blade. At least one load sensor is located at a position on the rotor blade remote from both a flap bending moment axis and an edge bending moment axis of the rotor blade. At the position, a flap bending moment component and an edge bending moment component of the load on the rotor blade are measurable. A load value is measured from the load sensor, and the measured load value is used to determine a flap bending moment component of the load and an edge bending moment component of the load, and optionally or additionally an axial force component of the load.

    Abstract: A yaw sensor for a wind turbine is described. The yaw sensor comprises a plurality of rotary switches, each configured to be coupled to a yaw drive gearbox of a wind turbine nacelle, the rotary switches each being operable to activate and deactivate respective associated electrical contacts in dependence on an amount of yaw rotation of the nacelle relative to a start position. Each electrical contact is active at a plurality of first yaw rotation ranges with respect to the start position, and inactive at a plurality of second yaw rotation ranges with respect to the start position, the first and second yaw rotation ranges being interleaved. The first yaw rotation ranges of the electrical contacts do not overlap each other between the start position and a first rotational position in a first rotational direction from the start position, and do not overlap each other between the start position and a second rotational position in a second rotational direction from the start position opposite to the first rotational direction. All of the electrical contacts are activated at the first rotational position and the second rotational position. The electrical contacts each generate a respective electrical signal when active. The activation of one or more of the electrical contacts between the first and second rotational positions confirms that the rotary switches are operating correctly, reducing the requirement for regular safety checks, and permitting yaw sensor supervision to be conducted by comparing pulses generated by the electrical contacts with the output of an angular encoder.
