Summary:To provide a wind power generator capable of diagnosing the presence or absence of abnormality.SOLUTION: A wind power generator includes a blade, a main shaft connected with the blade at one end, a speed-increasing gear connected with the other end of the main shaft, an output shaft connected with the speed-increasing gear at one end, a power generating unit connected with the other end of the output shaft, a vibration sensor, and an abnormality diagnosis unit. The power generating unit can rotate the output shaft and the main shaft by power running operation. The abnormality diagnosis unit determines the presence or absence of abnormality on the basis of data acquired by the vibration sensor during a period in which the power generating unit performs power running operation.SELECTED DRAWING: Figure 1 【課題】異常の有無を診断可能な風力発電装置を提供する。【解決手段】風力発電装置は、ブレードと、一端がブレードに接続されている主軸と、主軸の他端に接続されている増速機と、一端が増速機に接続されている出力軸と、出力軸の他端に接続されている発電部と、振動センサと、異常診断部と、を備える。発電部は、力行動作することで出力軸および主軸を回転させることが可能に構成されている。異常診断部は、発電部が力行動作している期間中に振動センサによって取得されたデータに基づいて異常の有無を診断する。【選択図】図1
