WIND TURBINE WHICH HAVE NACELLE FENCE

摘要

PURPOSE: A wind turbine having a nacelle fence is provided to minimize the vortex in a lower end of a blade by installing a fence in a nacelle along a flow direction of air. CONSTITUTION: A wind turbine comprises one or more nacelle fences(50). The nacelle fences are separately installed at constant intervals in a downstream direction of a rotor blade(30), and formed on an upper part of a tower. The nacelle fences are extended from a surface of a nacelle(20) along a flow direction of air. A cross section of the nacelle fence is inclined at a predetermined angle to a rotary shaft. The cross section of the nacelle fence is oppositely inclined to the rotary direction of the blade.
