| description | The invention relates to the field of wind power and can be used for creating and modifying wind energy installations such as to operate more efficiently in a wide range of wind conditions, including at low annual average wind speeds (3-6 m/s). A wind energy installation is controlled with the aid of an adjustable wind turbine power take-off system consisting of: a permanent magnet synchronous generator with a rotor position sensor; an active rectifier with a microprocessor controller; a power supply; a braking system; a ballast; and a down converter. An adjustment method for a wind energy installation of this type is proposed which increases the power coefficient across the entire range of working speeds and stabilizes the electromagnetic torque on the generator shaft when the wind speed is higher than a projected speed corresponding to a nominal power value. The adjustment method is based on controlling the rotation frequency of the wind turbine in accordance with a rotation frequency optimization algorithm which evaluates the change in energy generated across a set period of time and establishes a new rotation frequency value. |
