PROBLEM TO BE SOLVED: To control the operation of a wind power generator based on measured values of wind direction and wind speed not influenced by blade back wash.SOLUTION: A wind power generator comprises: a hub 8 for radially supporting a blade 2; a rotor 3 having a substantially conical nose cone 11 fixed to one end part of the hub 8; a nacelle 4 for rotatably supporting the rotor 3 around a rotor shaft A; a yaw drive part 6 for revolving the nacelle 4 in a horizontal direction; and a control part 14 for controlling the yaw drive part 6 so as to direct the nose cone 11 upwind. The nose cone 11 includes a first pressure measurement part 16, and a second pressure measurement part 17. The first pressure measurement part 16 is provided in a tip 11a of the nose cone 11, and the second pressure measurement part 17 is provided on the nose cone 11 by separating from the tip 11a toward the side of the hub 8. The control part 14 controls the yaw drive part 6, based on pressure measurement values by the first pressure measurement part 16 and the second pressure measurement part 17.SELECTED DRAWING: Figure 1 【課題】ブレードの後流の影響を受けていない風向風速の測定値に基づいて風力発電装置の運転を制御する。【解決手段】ブレード２を放射状に支持するハブ８と、ハブ８の一端部に固定された略円錐状のノーズコーン１１と、を有するロータ３と、ロータ３をロータ軸Ａ回りに回転可能に支持するナセル４と、ナセル４を水平方向に旋回させるためのヨー駆動部６と、ノーズコーン１１を風上に向けるべくヨー駆動部６を制御する制御部１４と、を備える。ノーズコーン１１には、第１の圧力測定部１６と第２の圧力測定部１７とが設けられる。第１の圧力測定部１６は、ノーズコーン１１の先端部１１ａに設けられ、第２の圧力測定部１７は、先端部１１ａからハブ８側に離間させてノーズコーン１１に設けられる。制御部１４は、第１の圧力測定部１６及び第２の圧力測定部１７による圧力測定値に基づいてヨー駆動部６を制御する。【選択図】図１
