A wind power generator may include a wind turbine, a first motor generator configured to be driven by the wind turbine, a second motor generator, at least one mechanism configured to be driven by the second motor generator, a power split mechanism that couples a first shaft connected to the first motor generator, a second shaft connected to the second motor generator, and a third shaft to each other such that the first shaft, the second shaft, and the third shaft are configured to rotate differentially with respect to each other, and a rotation restricting mechanism configured to prohibit or restrict rotation of the third shaft.

Wind power generator

A wind power generation device includes a blade, a main shaft of which one end is connected to the blade, a speed increaser connected to the other end of the main shaft, an output shaft of which one end is connected to the speed increaser, a power generation unit connected to the other end of the output shaft, a vibration sensor, and an abnormality diagnosis unit. The power generation unit is configured to rotate the output shaft and the main shaft by performing powering operation. The abnormality diagnosis unit diagnoses the presence or absence of an abnormality based on data acquired by the vibration sensor during a period in which the power generation unit performs powering operation.

Wind power generation device

A power generation device may include: a blade; a first rotation shaft; a differential gear mechanism; and a first motor generator. The differential gear mechanism may include: a pair of a first side gear and a second side gear; and a first ring gear connecting the first side gear and the second side gear to the first motor generator. The first side gear may be fixed to one end of the first rotation shaft, and the blade is connected to the other end of the first rotation shaft. In the differential gear mechanism, at least two of the first side gear, the second side gear and the first ring gear may be fixed to each other such that they are not able to rotate relative to each other.

Power generation device

A front straightening portion is formed at a front portion of a main body portion of a spat. In the front straightening portion, a front inclined surface is inclined backward with respect to a vehicle with decrease in distance to a lower side of the vehicle in a lateral view, and front lateral surfaces extend forward with respect to the vehicle from both end portions of the front inclined surface in a vehicle width direction, respectively. A traveling wind that hits the front lateral surfaces flows toward the front inclined surface side, and is caused to flow out downward with respect to the vehicle from the front straightening portion together with a traveling wind. The flow velocities of the traveling winds increase, the air resistance of the vehicle can be reduced, operation stability of the vehicle can be enhanced, and riding comfort performance of the vehicle can be enhanced.
