Abstract

There is described a method of determining an angular position of a nacelle (4) of a wind turbine (1), the nacelle (4) being rotatably mounted at an upper end of a tower (3), the lower end of the tower (3) being supported by a foundation (2). The method comprises obtaining and storing (21) a foundation angular position corresponding to a foundation reference point (13), the foundation angular position being relative to true north, determining (22) a tower angular position based on the foundation angular position and information indicative of an angular relation between foundation and tower, the tower angular position corresponding to a tower reference point (D), receiving (23) an encoder signal indicative of the angular position of the nacelle (4), detecting (24) that a sensor (15) mounted to the nacelle (4) is located in the vicinity of the tower reference point (D), and in response to the detecting: updating (25) the encoder signal such that the indicated angular position of the nacelle (4) corresponds to the tower angular position. Furthermore, a controller for a wind turbine, a wind turbine, and a wind farm are described.
