1. A wind turbine control device comprising:
an acquisition unit configured to acquire 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;
a determination unit configured to execute 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 and execute an operation history determination process of determining whether or not a result of the operation history comparison process satisfies a prescribed first condition; and
a control unit configured to control 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,
wherein the acquisition unit acquires the operation history data at the time of plasma generation indicating a relationship between at least two types of physical quantities and the operation history data at the time of stopping plasma generation indicating a relationship between at least two types of physical quantities, and
wherein the determination unit determines whether or not the prescribed first condition in which the relationship between at least two types of physical quantities indicated in the operation history data at the time of plasma generation matches the relationship between at least two types of physical quantities indicated in the operation history data at the time of stopping plasma generation is satisfied in the operation history determination process.
