POLYWIND ROTARY POWER SYSTEM OF CONTINENTAL APPLICATION Russian patent published in 2014 - IPC F03D3/02 

FIELD: power industry.

SUBSTANCE: invention can be used for power conversion of medium-velocity winds to electric power. Power system consists of a load-carrying mast, at the top of which there is a turning assembly with radially and opposite directed cross beams of equal length, on which at least two identical supporting grids are installed. In grid meshes of the same size there arranged are wind rotors with equal mass-dimensional parameters; their orthogonal turbines are combined into units on vertical shafts transmitting rotation through one- or two-stage multiplexers. Grids converge in vertical planes symmetrically to the mast a sharp angle, and their centres of gravity, which are assembled with wind rotors, are balanced relative to rotation axis of the turning assembly. Besides, in one of the horizontal tiers of supporting grids from their vertical symmetry axis and to leeward side there installed are flat orienting elements projecting beyond the basic structure outline.

EFFECT: generating electric power of high industrial duty at improvement of self-orientation of the device to wind and operating conditions of the turning assembly.
