WIND POWER GENERATING FACILITY STRESS ESTIMATION APPARATUS, WIND POWER GENERATING FACILITY STRESS ESTIMATION METHOD, AND WIND POWER GENERATING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a wind power generating facility stress estimation apparatus capable of measuring a stress of a wind turbine or monitoring the stress without providing a stress detection sensor beyond necessity.SOLUTION: A wind power generating facility stress estimation apparatus comprises: a similar wind condition selection unit 10 for selecting a similar wind condition of another wind turbine having the similar wind condition from input wind condition data; a stress value database 20 for storing stress values of a plurality of wind turbines; an estimated stress value calculation unit 30 for estimating a stress value of a stress-unmeasured wind turbine from the stress values stored in the stress value database 20 corresponding to the selected wind turbine; and a stress value database update unit 40 for updating the stress values of the plurality of wind turbines stored in the stress value database 20 on the basis of the estimated stress value S20 calculated by the estimated stress value calculation unit 30. The estimated stress value calculation unit 30 estimates the stress value of the stress-unmeasured wind turbine on the basis of a plurality of similarities of wind conditions selected by the similar wind condition selection unit 10 and a plurality of stress values extracted from the stress value database 20.SELECTED DRAWING: Figure 1
