Electricity: single generator systems inventions 12/08

20080309296 - Regenerative static excitation system for superconducting rotor: The present invention provides for a static excitation system for a superconducting rotor that comprises multiple brushes (12) in contact with the superconducting rotor winding (6), normally via collector rings and field leads. A power conditioning device (16) is connected to the brushes (12), and an energy storage device (18)... Agent: Siemens Corporation Intellectual Property Department

20080303489 - Controller of doubly-fed induction generator: Disclosed is a controller of a grid coupled type doubly-fed induction generator having a multi-level converter topology, which can control the doubly-fed induction generator having a high voltage specification and can perform a fault ride-through function, an anti-islanding function and a grid voltage synchronization function required for a dispersed power...

20080303490 - Generator with quadrature ac excitation: A generator system is configured to supply two phase excitation current from an exciter rotor to a main generator rotor. When driven by a variable speed prime mover, the generator system provides relatively constant frequency AC power by independently controlling the main rotor flux rotational speed. The generator system includes... Agent: Honeywell International Inc.

20080297119 - Fluid-induced energy converter with curved parts: An energy converter for inducing membrane vibrations of a membrane when subject to a fluid flow, and converting the vibrations into another form of energy, such as electricity. The energy converter includes at least one flexible membrane, at least one electrical conductor and at least one magnetic field generator configured... Agent: Wilson Sonsini Goodrich & Rosati

20080297120 - Electronically redundant spacecraft power and attitude control system: An energy storage flywheel system for a spacecraft is implemented with an electronically redundant power and attitude control system. In particular, the system includes a plurality of flywheels, and a multi-channel processing module and a multi-channel power control module associated with each flywheel. Each multi-channel processing module includes a plurality... Agent: Honeywell International Inc.
