FIELD: physics.
SUBSTANCE: group of inventions relates to a wind turbine, a pump for it, a system and a method for its installation and/or maintenance, a method for maintenance of a wind turbine power plant with a number of wind turbines. Wind turbine (1) comprises a mast and head (6) installed on the upper end of the mast with possibility of rotation around the axis of head (6). Air screw (9) is installed on head (6), made with possibility of rotation around screw (9) axis. There is hydraulic pump (10) driven by screw (9). Hydraulic pump (10) is made essentially inside screw (9). Hydraulic pump (10) is located in bushing (21) of screw (9) so that it is possible to extract hydraulic pump (10) from head (6) together with screw (9).
EFFECT: group of inventions is aimed at creation of a design of a wind turbine with a hydraulic pump, which is simple for production and / or maintenance.
