摘要: 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.

摘要: The wind power generation device includes a blade, a power distribution unit, a first generator, a second generator, a clutch unit, and a control unit. The control unit controls connection and disconnection of the clutch unit such that the clutch unit is disconnected when the wind speed input to the blade is smaller than a predetermined first wind speed value and the clutch unit is connected when the wind speed input to the blade is larger than a predetermined second wind speed value.

摘要: A generator system for connection to a vehicle axle. The generator system includes: an electrically-actuated clutch having an engaged position and a disengaged position; a generator and a processor. The generator includes: a rotor configured to be selectively connected, via the clutch, to the vehicle axle; and a stator. In the engaged position, the rotor is connected to the vehicle axle via the clutch such that torque from the vehicle axle is transmitted to the rotor. In the disengaged position, torque from the vehicle axle is not transmitted to the rotor. The processor is configured to control the clutch to actuate between the engaged and disengaged positions, and the processor is configured to monitor an electrical output of the generator, wherein the processor is configured to command the clutch to move to the disengaged position if the electrical output moves outside a predetermined range.

摘要: Systems and methods for improving shifting of a transmission are described. The systems and methods may be applied to automatic or manual transmissions, but the systems and methods may be particularly suited for automatic transmissions. In one example, electrical input to an alternator and electrical output from the alternator is adjusted in response to a request to upshift a transmission.

摘要: At least one of a plurality of generators is a first generator configured such that a relationship of a generator output voltage with respect to a generator active power output from the generator to a corresponding first AC wiring portion has a predetermined first drooping characteristic. The control device is configured to generate a drive signal for a power conversion device by deciding a target value of a first control element such that a relationship of an AC wiring portion voltage with respect to a power conversion device active power output from the power conversion device to a first AC wiring portion corresponding to a first generator has a predetermined second drooping characteristic and correcting the target value of the first control element according to a DC voltage at a DC wiring portion.

摘要: A generalized frequency conversion system for a steam turbine generator unit. The system comprises at least a variable speed steam turbine with an adjustable rotating speed, a water feeding pump, a variable frequency generator operating at a variable speed, a speed increasing gearbox with a fixed rotating speed ratio, a variable frequency bus and an auxiliary machine. With a change in load of the unit, parameters of steam entering the variable speed steam turbine and an extracted steam amount are adjusted (changed) accordingly, so that the rotating speed of the steam turbine changes accordingly. In this way, on one hand, the rotating speed of the water feeding pump is changed through the speed increasing gearbox; and on the other hand, the frequency of alternating current outputted by the variable frequency generator is changed. In the present invention, there is no need to additionally provide other types of frequency converters, and the system is simple, reliable, low in cost and high in efficiency.
