09428061 Wind turbine for electric car||US||30.08.2016|
||13986792||Peter W. Ripley||Peter W. Ripley|
A system for harnessing wind energy to charge the electric storage battery of a vehicle, whether the vehicle is parked or in motion. While the vehicle is being driven, a roof-mounted, internal wind turbine harnesses wind energy and causes rotation of the shaft of an electric generator mounted to an interior surface of the roof. For charging the battery while the vehicle is parked, an external wind turbine is storable in the vehicle when not in use and attaches to the internal wind turbine. Cups of the kind used in cup anemometers are attached to radial arms that extend from an external shaft of the external wind turbine and catch ambient wind currents while the vehicle is parked, causing the external shaft and the generator shaft to rotate.

20160245257 SYSTEM FOR PITCH CONTROL||US||25.08.2016|
||15029714||MITA-TEKNIK A/S||Torben Jensen|
A system for electric pitch control primarily for wind turbine blades, has at least one first electric motor which is electrically coupled to a first electronic control device, which electronic control device controls the operation of the motor which drives a gear mechanism via a clutch that has a tooth wheel that drives a tooth ring which is mechanical fixed to the root of a wind turbine blade for performing pitch regulation. To improve the reliability of an electric pitch control system the system has at least one second motor which is electrically coupled to a second electronic control device which is coupled to the power grid and controls the operation of the second motor. The second motor has a shaft which drives a second gear mechanism via clutch. The second gear mechanism has at least one second tooth wheel, which second tooth wheel drives the tooth ring.
20160245258 TURBINE WITH YAW BRAKE MECHANISM HAVING A ROTOR LOCK AND A CORRESPONDING RECEPTACLE||US||25.08.2016|
||14629653||LOCKHEED MARTIN CORPORATION||Stephen FIRKSER|
A yaw brake mechanism is described for maintaining a yawing structure, such as a nacelle of a fluid turbine, at a desired orientation or azimuthal heading about a reference or yaw axis. The yaw brake mechanism uses one or more rotor locks and one or more receptacles that cooperate with one another to achieve the locking function. One of the rotor locks is actuatable so that a portion thereof can be engaged in one of the receptacles to lock the yawing structure. The number of rotor locks and receptacles can be selected to allow the yawing structure to achieve any azimuth heading around the full 360 degrees of the yaw axis with various degrees of accuracy. The yaw brake mechanism allows the yawing structure to maintain multiple headings while being subjected to extreme moment and force loads in a low mass, low height, low cost solution.
20160245259 A METHOD FOR CONTROLLING A WIND POWER PLANT AND A WIND POWER PLANT||US||25.08.2016|
||15031044||VESTAS WIND SYSTEMS A/S||Manoj GUPTA|
A method for controlling a wind power plant, the wind power plant including a plant controller for controlling a plurality of wind turbine generators. The method for controlling a wind power plant allows the wind power plant to continue operating through a grid fault in a weak grid environment. In the method, a fault recovery process is carried out with a wind turbine power controller during a wind turbine fault recovery state to determine a grid voltage (VWTG), compare the grid voltage to a predetermined reference voltage (Vref) to obtain a difference value, and determine a current reference (QrefVC) based on the difference value for generating a reactive current (Idref) for regulating the grid voltage to the predetermined reference grid voltage. A corresponding wind power plant is further provided.

20160245261 FLOATING WIND POWER PLANT||US||25.08.2016|
||15027859||LINNHOFF OFFSHORE AG||Jens CRUSE|
The invention relates to an improved, in particular simpler, lighter, mechanically more stable and operationally more reliable offshore wind power plant (100) that can float. By means of a cable (110) constructed as a combination of a power line that is held at least virtually without loading and a holding cable that absorbs all the mechanical forces that occur for holding the wind power plant on a single fixed-location anchoring point (111), said power plant can be connected to the anchoring point such that the power plant can move with six degrees of freedom. A coupling (112) is arranged at a single connecting point (118) between the cable and the wind power plant and, to make an electrical connection, is constructed with a sliding coupling and, for mechanical transmission of force, is constructed with a swivel coupling. The wind power plant has a supporting unit (101) constructed as a semi-submersible having ballast units (102) and buoyancy units (103), in particular a floating unit, and a supporting mast (104) which is firmly connected to the supporting unit and has a machine gondola (105) fixedly arranged on the latter and having at least one rotor (106) and at least one electric generator. The highest possible horizontal distance is formed between the connecting point and a substantially vertical plane of rotation of the rotor.
