Wind turbine wake calculation device and wind turbine wake calculation method

摘要

Problem to be solved: to provide a wind turbine wake calculation device and a wind turbine wake calculation method capable of calculating the state of the wake in the windmill more accurately with fewer arithmetic operations.A wind turbine wake calculation device according to the present embodiment isA computational grid generator for generating mesh models composed of multiple computational grids andTo the range of the computational grid corresponding to at least a portion of the range from the rotation center of the blade to the first diameterA first model generator for generating an actuator disk part modeled as a fixed surface of wind turbine rotors is proposed.To the range of the computational grid corresponding to at least a portion of the range from the first diameter to the rotor diameterA second model generator which generates a solid part modeled as a shielding part of a wind turbine rotor is used.Based on governing equationAn operation control unit for calculating wind speed and wind direction for each calculation grid using an actuator disk and a solid part, and.Diagram
