  • For a wind turbine, which parts do not seem to play an important role in wind power generation?

    Adjust the direction, when the direction of the fan impeller's scavenging surface is not correct, it will lead to the inconsistency of air flow velocity on both sides of the stern rudder, and the pressure will also be different. The surface of the impeller of the wind turbine is always perpendicular to the wind direction through the tail fin. According to the trigonometric function of energy loss, when perpendicular to the wind direction, the tangent of the angle between the impeller and the wind direction is 1, and there is no loss. The wind energy can be fully converted into the rotational kinetic energy of the wind wheel.

    When the wind blows, if there is an angle between the tail and the wind direction, a tangential force will be exerted to push the fan around the tower until the angle with the wind direction is 0. This can automatically adapt to the wind direction. In addition, there is no tail on a large wind turbine because it is too heavy and can't rotate freely. The connection between large wind turbine and tower is usually through large roller bearing or slider ring gear, and the rotation of engine room is controlled by yaw drive.

    The wind direction is measured by the wind speed and direction indicator on the left and right sides of the tail. The custom anemometer is an ultrasonic generator receiver. The ultrasonic transmission time of two anemometers is affected by the wind speed and wind direction between them. Hidden in the tail of a large wind turbine is a huge water-cooled radiator. It's used to cool the generator.
