Abstract
A rotor of a wind turbine is disclosed with a pitch system locking arrangement to lock the position of a wind turbine rotor blade. A rotor comprises a rotor hub and a rotor blade, whereby the rotor blade is connected to the hub via a bearing, to be rotatable in respect to the hub in a pitch movement. The rotor blade comprises a root section, and the root section comprises a plate, that at least partially covers the cross section of the rotor blade. A certain predetermined rotational position of the rotor blade with respect to the hub is a locked position. The hub includes a locking pawl. The plate comprises an opening, and the locking pawl is at least partially located in the opening of the plate, when the rotor blade is in the locked position.
