Abstract: A wind turbine control device acquires operation history data at the time of plasma generation indicating an operation history of a first wind turbine when a plasma has been generated by plasma electrodes installed on a blade and operation history data at the time of stopping plasma generation indicating an operation history of the first wind turbine when no plasma has been generated by the plasma electrodes, executes an operation history comparison process of comparing the operation history data at the time of plasma generation with the operation history data at the time of stopping plasma generation, executes an operation history determination process of determining whether or not a result of the operation history comparison process satisfies a prescribed first condition, and controls at least one of the plasma electrodes and at least one of the first wind turbine and a second wind turbine different from the first wind turbine on the basis of a result of the operation history determination process.
