Patent number: 7095128Abstract: A method and corresponding apparatus for regulating a system that produces electric power, the system including an electric alternator having a rotor integral with a rotating part of a wind machine to form a rotary assembly, and a power electronics module, the method including the steps of: producing an alternating current at output terminals of the alternator; converting the alternating current produced by the alternator into modulated pulses of direct current. Alternating electric current produced by the alternator is regulated by controlling the speed of rotation of the rotary assembly by resisting torque imposed by the alternator in response to modulating the pulses of continuous current produced by the converted the alternating current.Type: GrantFiled: February 4, 2002Date of Patent: August 22, 2006Assignee: Jeumont S.A.Inventors: Jean-Marc Canini, Yves Milet, Patrick Brutsaert

Patent number: 6921243Abstract: The system comprises a nacelle mounted to turn about a vertical axis on the top of a mast and carrying a rotary portion which rotates about a substantially horizontal axis in a large diameter bearing. The rotary portion comprises a hub to which blades are fixed. The system has an electric generator comprising a stator and a rotor in the shape of a disk. The rotor is fixed by a connecting member to the hub adjacent the bearing so that the forces exerted by the wind on the rotary portion are transmitted directly to the bearing without passing through the electric generator.Type: GrantFiled: June 6, 2001Date of Patent: July 26, 2005Assignee: Jeumont S.A.Inventors: Jean-Marc Canini, Yves Milet, Patrick Brutsaert
