A wind-power and hydraulic generator apparatus has a wind power device, a drive device, multiple pump devices, a reservoir device and a hydraulic device. When the wind blows, the wind power device generates and stores electricity and the drive device drives the pump devices to pump water into the reservoir device. Then the reservoir device generates a water jet enabling the hydraulic device to generate electricity. When the wind does not blow, the electricity stored in the wind power device still enables the water to circulate and to generate the water jet. Whether the wind blows or not, the water of the reservoir device can keep circulating to generate the water jet and the hydraulic device can keep generating electricity. Accordingly, the wind-power and hydraulic generator apparatus can use wind power to generate a water jet.

The rods of the latter are in a ball-jointed connection with the body (A) in order to offer the latter a maximum degree of freedom in space. A rigid arm (C) is set on one side of the wheel (F) and held on the other side, in a pivot connection, on a U-shaped section piece (B). Having a circular satellite motion, the latter rotates with the wheel (F) while sliding over a peripheral region of the body (A). When the wind acts on the body (A), the latter pivots with the section piece (B) and pushes the rods of the actuating cylinders (D). Having a circular satellite motion, the section piece (B) rotates while sliding over a peripheral region of the body (A), thus changing the fulcrum of the moment of the resultant force of the wind (the pivot connection of the section piece (B)) which is applied to the body (A). The rods of the actuating cylinders (D) will consequently be pulled and pushed, while having a cyclical translational motion. Set on the axle (L), a nacelle (J) primarily contains a hydraulic motor (H) and an electric generator (G), which can be coupled via a speed-increasing gear. During the reciprocal motions of the pistons of the actuating cylinders (D), a set of valves ensures a one-way flow of hydraulic fluid in the “go and return” hydraulic circuits, whether by pulling or by pushing. The “go and return” hydraulic circuits are, moreover, linked to the hydraulic motor (H). In order to allow the system (SCEE) to be held facing the wind and to pivot on the mast ( 1 ), its orientation can be ensured ...

Generator torque control methods

Номер: US20130207394A1

A wind turbine typically includes a generator and a rotating mechanical system having a natural period. The present invention relates to a method of controlling generator torque that minimises oscillations in the speed of the generator rotor. In the event of a grid fault or transient, or a fault in the power converter, the generator torque is decreased at a substantially constant rate with respect to time as shown in graph (c). The rate at which the generator torque is decreases is proportional to the nominal rated torque of the generator and inversely proportional to an integer multiple of the natural period of the rotating mechanical system.

An embodiment of Horizontal and Vertical Axis Wind Generator (HVAWG) concept with the rotating big and small wings, the magnectic coils, magnetic field magnets attached to the wings, generator motor, generator motor coils and generator motor magnetics is described. The generator motors in the present invention use the generator motor coils, the generator motor magnets, magnetic filed coils and magnetic field magnets to amplify the power using the repulsive characters of the same magnetic poles. Also, both the outside and the inside parts of the generator motors rotate the present invention while the inside parts of the generator motors rotate in the traditional wind generators. These features allows for a number of improvements over the current state of the art including damage protection, scalability depending the application and the speed regulation ability to remain operational during high wind and low wind conditions. In addition, the invention described here is scalable for cars, boats, airplanes, motor cycles, camping cars, drones, homes, offices, and power plants. Finally, the material of the horizontal and vertical axis wind generator is aluminum which is lighter, is easier to be installed, is durable and is corrosion resistant.

A planetary carrier for a gear stage of a planetary gearset includes at least one planetary pin that is disposed in a rotationally fixed manner in the planetary carrier, and a pair of tapered roller bearings that are disposed on the planetary pin supporting a planet gear. The planetary pin is fastened by means of a pin screw connection, which comprises a pin screw and a nut, to the planetary carrier. The tapered roller bearings are clamped against each other between the planetary carrier and the planet pin and are axially pretensioned by means of the pin screw connection. 1.
