CONTROL SYSTEM, LEARNING DEVICE, CONTROL DEVICE AND CONTROL METHOD

To provide a control system that can control rotation of a windmill so that rotation speed in the windmill is optimized even in an unstable wind state.SOLUTION: The control system comprises: a learning part that learns correspondence information between wind speed and rotation of a windmill on the basis of wind speed information indicating the wind speed in an installation place of the windmill, rotation information relating to the rotation of the windmill, relation information of the wind speed and the rotation, which indicates an allowable range and a target for the rotation; a memorizing part that memorizes the correspondence information between the wind speed and the rotation; a state detecting part that detects wind speed in a case where a rotation speed control parameter for controlling rotation speed of the windmill is set on the windmill; a determining part that determines the rotation information on the basis of the wind speed detected by the state detecting part and the correspondence information; and a control part that controls rotation of the windmill so that rotation of the windmill is within the allowable range and gets close to the target, on the basis of the rotation information determined by the determining part.SELECTED DRAWING: Figure 12 【課題】不安定な風況であっても風車における回転速度を最適化させるように制御を行うことが可能となる制御システムを提供する。【解決手段】前記風車の設置場所における風速を示す風速情報、前記風車の回転に関する回転情報、及び、前記風速と前記回転の関係情報であって前記回転の許容範囲と目標とを示す関係情報に基づいて、前記風速と前記回転との対応情報を学習する学習部と、前記風速と前記回転の対応情報を記憶する記憶部と、前記風車の回転数を制御する回転数制御パラメータを前記風車に設定した場合における風速を検出する状態検出部と、前記状態検出部により検出された風速、及び前記対応情報に基づいて、前記回転情報を決定する決定部と、前記決定部により決定された回転情報に基づいて、前記風車の回転が前記許容範囲に収まり、尚且つ前記目標に近づくように、前記風車の回転を制御する制御部とを備える。【選択図】図１２
