  • Yaw control-by-rudder type tidal stream power generation apparatus and yaw control method of the same
    Patent number: 9494130
    Abstract: A yaw control-by-rudder type tidal stream power generation apparatus includes: a nacelle used in a tidal stream power generator that converts flowing energy of a tidal stream to generate electric power, and located in the tidal stream to be rotatable about a first rotating shaft; a rotor provided at one side of the nacelle with reference to the first rotating shaft, and configured to be rotated by the flowing energy of the tidal stream; a rudder unit provided at the other side of the nacelle with reference to the first rotating shaft, and including a rudder fixed to the nacelle and a variable rudder rotatably connected to the nacelle; and a control unit configured to control the rotation of the variable rudder. When the flow direction of the tidal stream is changed, the rotation of the variable rudder is controlled by the control unit.
