1. A vertical wind turbine comprising:
a plurality of vertical blades that are supported by a plurality of angularly spaced rotor arms of a rotor that extend from a rotor hub, which are each fastened to a respective vertical blade axis such that they are pivotable around a respective blade rotation axis independently of one another and are supported rotatable on a common circular path around a vertical rotor rotation axis, the plurality of vertical blades having one or more pitch motors,
wherein:
the vertical wind turbine is configured to control a pitch angle of the blades at least in a partial load mode of the vertical wind turbine such that the blades rotate with a constant tip speed ratio; and
devices mounted to allow components to be assembled and disassembled without using a crane, wherein the devices comprise a mobile cable winch on the ground and deflection sheaves in a tower supporting the rotor, and wherein the vertical blades can be assembled to and disassembled from the rotor by a crane placed on a rotor arm from the plurality of rotor arms.
