Method for operating a wind turbine

InactiveUS6965174B2Voltage fluctuationUnwanted fluctuationWind motor controlMachines/enginesPower gridWind force
The present invention relates to a method for operating a wind turbine with an electrical generator, drivable by a rotor, for supplying electrical power to an electric grid, in particular to the loads connected thereto. The object of the present invention is to define a method for operating a wind turbine and to provide a wind turbine and/or a wind farm that is capable, even when the output of non-reactive power fluctuates, of reducing or at least of insignificantly increasing the unwanted fluctuation in voltage at a predefined point in the grid compared to the situation with no wind turbine(s). Method for operating a wind turbine with an electrical generator, drivable by a rotor, for supplying electrical power to an electric grid, in particular to the loads connected thereto, characterized in that the phase angle φ is changed in response to at least one voltage measured in the grid.

False activation reducing centrifugal activation system

The present invention is directed to a false activation reducing centrifugal activation system. The system is an activation system that may be used to activate a wide variety of functionalities in a wide variety of devices. The functional elements to the system are a device housing, a power supply module, and one or more activation modules that are activated by a particular motion of the housing, such as when the device housing is able to at least partially spin or rotate about one or more axis' of rotation. The disclosed activation modules include a centrifugally activated electronic system that allows a device's functionality to be turned on or off by moving the device's housing in a particular fashion. In this way, a device equipped with the disclosed centrifugally activated electronic system does not need to have a manual ON/OFF switch or fragile mechanical switch. Instead, the disclosed system allows one or more of a device's functionalities to be activated (or de-activated) when the device's housing moves in the proper manner, while reducing unwanted activations that would be caused by slight and/or unintentional movement. Any sort of promotional product may be equipped with the disclosed false activation reducing centrifugal activation system, including, but not limited to, toys for children, pet toys, novelty devices, and corporate giveaways.

Motor generator including interconnected stators and stator laminations

An axial field motor/generator having a rotor that includes at least three annular discs magnetized to provide multiple sector-shaped poles. Each sector has a polarity opposite that of an adjacent sector, and each sector is polarized through the thickness of the disc. The poles of each magnet are aligned with opposite poles of each adjacent magnet. Metal members adjacent the outermost two magnets contain the flux. The motor/generator also has a stator that includes a stator assembly between each two adjacent magnets. Each stator assembly includes one or more conductors or windings. Although the conductors may be formed of wire having a round, uniform cross-section, they may alternatively be formed of conductors having a tapered cross-section that corresponds to the taper of the sectors in order to maximize the density of the conductor in the gap between axially adjacent poles. The conductors may also alternatively be formed of traces in a printed circuit, which may have one or more layers. Each stator assembly may be removably connectable to another stator assembly to provide modularity in manufacturing and to facilitate selection of the voltage at which the motor/generator is to operate. Electrical contacts, such as pins extending from the casing, may removably connect the conductors of adjacent stator assemblies. A magnet may be dynamically balanced on the shaft by hardening a thin ring of cross-linked resin between the magnet and the shaft while the shaft is spun, using ultraviolet light to polymerize the resin.
