TLDR
In this paper, a wind power turbine tower is provided to control the vibration characteristics of a turbine tower by a movable mass, to have the required vibration characteristics regardless of mechanism or a structure or the rotational speed of a blade in a wind turbine tower, and to correspond appropriately by controlling vibration characteristics under unexpected circumferences.Abstract:
PURPOSE: A wind power turbine tower is provided to control the vibration characteristics of a wind power turbine tower by a movable mass, to control the vibration characteristics of a wind power turbine tower to have the required vibration characteristics regardless of mechanism or a structure or the rotational speed of a blade in a wind power turbine tower, to reduce the cost of planning, manufacture and construction of a wind power turbine tower, and to correspond appropriately by controlling vibration characteristics under unexpected circumferences. CONSTITUTION: A wind power turbine tower(100) comprises a tower type structure(200) installed to a power generation site using wind power, a power generation unit(300) provided to the top of the tower type structure, a blade unit(400) connected to the power generation unit and composed of plural blades(410), and a vibration characteristics control unit(500) including a mass(M) provided to the inside or the outside of the tower type structure to be movable and moving the mass to control the vibration characteristics of the whole wind power turbine tower.read more
