9372 results about "Wind force" patented technology

Force, Wind and Pressure. Force, generally defined as a push or pull, can be calculated using the formula force equals mass times acceleration (F = ma). Wind also pushes and pulls, generally with greater force when moving faster.

Wind turbine

InactiveUS7042109B2Improve efficiencyCost per unit power generationWindingsWind motor controlRotational energyAir core
A wind turbine for generating electrical power from wind energy includes a turbine rotor mounted for rotation in wind, and having multiple blades for converting energy in the wind into rotational energy. A generator is coupled with said turbine rotor such that said turbine rotor drives said generator. The generator has a stationary air core armature that is located in a magnetic airgap between two generator rotor portions. The generator rotor portions have circumferential arrays of multiple alternating polarity permanent magnets attached to ferromagnetic back irons such that the permanent magnets drive magnetic flux back and forth between each rotor portion and through the stationary air core armature. The stationary air core armature has multiple phase windings of multiple individually insulated strand conductor wire that is wound with two separate portions including an active length portion and an end turn portion. The end turn portion is located outside the magnetic airgap and traverses predominately circumferentially, and the active length portion is located in the magnetic airgap and traverses predominately non-circumferentially and perpendicular to the direction of the magnetic airgap. The end turn portion has a thickness that is greater than the thickness of said active length portion in the direction of said magnetic airgap. AC voltage is induced in the multiple phase windings as the turbine rotor rotates.

System, method and computer program product for enhancing commercial value of electrical power produced from a renewable energy power production facility

InactiveUS20050127680A1Increase power valueInherent market valueWind motor controlEngine fuctionsPower exchangeRenewable power generation
A method, system and computer program product enhance the commercial value of electrical power produced from a wind turbine production facility. Features include the use of a premier power conversion device that provides an alternative source of power for supplementing an output power of the wind turbine generation facility when lull periods for wind speed appear. The invention includes a communications infrastructure and coordination mechanism for establishing a relationship with another power production facility such that when excess electrical power is produced by the wind turbine facility, the excess may be provided to the power grid while the other energy production facility cuts back on its output production by a corresponding amount. A tracking mechanism keeps track of the amount of potential energy that was not expended at the other facility and places this amount in a virtual energy storage account, for the benefit of the wind turbine facility. When, the wind turbine power production facility experiences a shortfall in its power production output it may make a request to the other source of electric power, and request that an increase its power output on behalf of the wind turbine facility. This substitution of one power production facility for another is referred to herein as a virtual energy storage mechanism. Furthermore, another feature of the present invention is the use of a renewal power exchange mechanism that creates a market for trading renewable units of power, which have been converted into “premier power” and/or “guaranteed” by secondary sources of power source to provide a reliable source of power to the power grid as required by contract.

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.
