A CONTROL METHOD FOR REDUCING WIND LOAD OF A WIND GENERATOR UNIT DEPENDED ON EXTERNAL ENVIRONMENT

摘要

According to an embodiment of the present invention, a control method for reducing a load depending on an external environment may comprise: an external environment measurement step of measuring a wind speed from a wind speed sensor installed in a wind power generation unit; a turbulence intensity derivation step of deriving turbulence intensity (TI) from a real-time wind speed measured by the wind speed sensor; and an operation control step of reducing an output (P) by applying an additional generator set speed to pitch control logic in accordance with the measured external environment to increase a pitch angle.
