Patent number: 7740448Abstract: A method for controlling a pitch control system of a wind turbine includes providing a charged backup battery configured to supply no energy to a DC link when full AC input power is available, wherein the DC link includes a DC link capacitor. The method further includes using energy stored in the DC link capacitor to operate a pitch control system during a loss or dip of AC input power, and maintaining charge on the DC link capacitor using the charged backup battery as voltage across the DC link capacitor drops during the operation of the pitch control system.Type: GrantFiled: September 9, 2005Date of Patent: June 22, 2010Assignee: General Electric CompanyInventors: Brian Nedward Meyer, Jeffrey Alan Melius, Cyrus David Harbourt, Christopher L.

Patent number: 7235895Abstract: A rotor for a wind turbine generator includes a rotatable hub forming a cavity. A plurality of rotor blades is connected to the hub. A heat sink is at least partially positioned within the cavity and extends along a portion of a corresponding rotor blade. The heat sink includes a bottom surface mounted on a thermal energy generating component of the wind turbine generator. An opposing top planar surface includes a plurality of pins extending therefrom. The pins form an air flow path through the pins to dissipate the generated thermal energy from the thermal energy generating component.Type: GrantFiled: October 13, 2005Date of Patent: June 26, 2007Assignee: General Electric CompanyInventors: Jeffrey Alan Melius, Cyrus David Harbourt, Brian Matthew Aiken, Christopher Todd Moore, Howard Ross Edmunds, Brian Eric Lindholm, Christopher McMenamin, William John Bonneau, Amy Marlene Ridenour, Andrew Scott Wilkinson
