DEVICE, METHOD AND PROGRAM FOR ADJUSTING RESTRICTION ON OPERATION OF WINDMILL

摘要

An object is to suppress reduction of energy production as much as possible while ensuring an expected lifetime. There is provided a device of adjusting a curtailment strategy for a wind turbine (10), the device including: a fatigue equivalent load calculation unit (11) that calculates a fatigue equivalent load for evaluating a fatigue damage of the wind turbine in a predetermined time period by using load data of the wind turbine; and a setting value update unit (12) that compares the fatigue equivalent load with a reference load determined by an expected lifetime of the wind turbine, and, when a difference between the fatigue equivalent load and the reference load exceeds a predetermined threshold value, updates the condition setting value for the curtailment that is currently employed according to the difference.
