To provide a wind power generation device control system capable of effectively reducing a wind load acting on a windmill.SOLUTION: In a wind power generation device control system, a wind velocity prediction section predicts wind velocity prediction data of wind flowing into a wind receiving surface of a wind power generation device. A calculation section calculates a wind load acting on the wind power generation device and a power generation amount thereof based on the wind velocity prediction data predicted with the wind velocity prediction section. An operation control section outputs an operation torque command value of the wind power generation device based on the wind load and power generation amount calculated with the calculation section. The wind velocity prediction section acquires wind velocity data including wind velocity values measured at a plurality of different locations in a vertical direction with respect to a plurality of azimuth orientations and selects the wind velocity data with respect to one azimuth orientation corresponding most to a wind direction at a height of a nacelle measured with a nacelle measurement section, from the wind velocity data with respect to the plurality of azimuth orientations, as the wind velocity prediction data.SELECTED DRAWING: Figure 1 【課題】風車が受ける風荷重を効果的に低減することができる風力発電装置の制御システムを提供する。【解決手段】実施の形態による風力電池発電装置の制御システムの風速予測部は、風力発電装置の受風面に流入する風の風速予測データを予測する。算出部は、風速予測部により予測された風速予測データに基づいて、風力発電装置が受ける風荷重を算出するとともに風力発電装置の発電量を算出する。運転制御部は、算出部により算出された風荷重および発電量に基づいて、風力発電装置の運転トルク指令値を出力する。風速予測部は、鉛直方向で互いに異なる複数の位置で計測された風速値を含む風速データを複数の方位について取得するとともに、複数の方位についての風速データから、ナセル計測部により計測されたナセル高さ風向に最も沿う一の方位についての風速データを風速予測データとして選定する。【選択図】図１
