Patent number: 6998728Abstract: An electrical system and method for a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator rotating on a common shaft includes an inverter circuit connectable either to an output circuit or the stator winding of the alternator. A control circuit during a start-up mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the output circuit. During the power out mode, current data is sensed and is used for current limit and/or power balancing.Type: GrantFiled: October 3, 2003Date of Patent: February 14, 2006Assignee: Elliott Energy Systems, Inc.Inventors: Suresh C.

Patent number: 6989610Abstract: An electrical system for a turbine/alternator comprising a gas driven turbine and a permanent magnet alternator rotating on a common shaft includes an inverter circuit connectable either to an AC output circuit or the stator winding of the alternator. A control circuit during a startup mode switches the inverter circuit to the stator winding of the alternator and during a power out mode switches the inverter circuit to the AC output circuit. Thus, during the startup mode, the alternator functions as a motor to raise the speed of the turbine to a safe ignition speed and in the power out mode the electrical system outputs the AC output circuit, electrical power having a frequency unrelated to the rotation speed of the alternator.Type: GrantFiled: May 28, 2003Date of Patent: January 24, 2006Assignee: Elliott Energy Systems, Inc.Inventors: Suresh C.

Patent number: 6698208Abstract: An atomizer for use with a combustor in a gas turbine has a body with a fuel passageway extending through the center of the body. A plurality of channels extends within the body about the passageway centerline, and are oriented along a circumferential angle about the passageway centerline to deliver air at the discharge end of the passageway with an axially whirling motion. The channels are simultaneously oriented along an axial angle about the passageway centerline, thereby directing the flow of air to converge toward the passageway centerline, mix with the fuel, and then at least in part diverge from the passageway centerline. The whirling air intersects with the fuel at the exit of the nozzle to effectively atomize both the air and fuel thereby providing a homogeneous air/fuel mixture to the combustion chamber.Type: GrantFiled: December 14, 2001Date of Patent: March 2, 2004Assignee: Elliott Energy Systems, Inc.Inventor: J.
