WIND POWER PLANT AND METHOD OF WIND POWER PLANT OPERATION Russian patent published in 2017 - IPC F03D7/02 

FIELD: power industry.

SUBSTANCE: wind power plant includes a rotor (106) comprising at least two rotor blades (108); an electric generator (200) directly or indirectly connected to the rotor (106) of the wind power plant and generating electric power when the rotor (106) rotates; and a control unit (120) for controlling the operation of the wind power plant. The control unit (120) activates the first operating mode in the event of a malfunction if the power supply (130) parameters exceed or decrease below the threshold value. The control unit (120) in the first mode of operation incase of a fault is configured to reduce the rotation speed of the rotor (106) to zero and to activate the electric consumer (400) to consume electric power generated by the generator (200) in the fault mode. The control unit (120) is configured to activate the second operating mode in the event of a malfunction if the power network parameters exceed or decrease below the threshold value. The control unit (120) in the second mode of operation in the event of a malfunction is configured to control the wind power plant in such a manner that said control unit takes power from the supply network and consumes said power by the electrical consumer (400).

EFFECT: increase the responsiveness to the power network malfunction to which the wind power plant is connected.
