WIND FARM Russian patent published in 2017 - IPC H02J3/38 

FIELD: electricity.

SUBSTANCE: wind farm (1) for wind power generation comprises of at least two wind turbines (2) for generating electric power and a common device (8) for supplying the generated electric power or a part thereof to the power supply network (14). The wind turbines (2) and the supply device (8) are connected via a DC voltage electrical network (4) to supply electric power, generated by the respective wind turbines (2) as DC current, to the common supply device (8). The DC voltage network (4) has a DC voltage in the range of 5-10 kV, and each wind turbine (2) comprises of the following elements: an AC generator (18), a rectifier (20) for rectifying the generated AC to the first DC having the first DC voltage, and a step-up converter (30) for stepping up the first DC and the first DC voltage to the second DC and the second DC voltage which is greater than the first DC voltage. The DC voltage includes a bus (6) and a plurality of line connections, and wherein the second DC voltage is supplied to the wind farm DC voltage network.

EFFECT: increased operational characteristics inside a wind farm and increased efficiency of its operation.
