Abstract: A method is provided for encapsulating permanent magnets of a rotor of a generator. Magnets, which are shorter than a rotor yoke in an axial direction, are placed outside of the yoke leaving a short portion of the yoke free at both ends. Spacers of a non-magnetic material are placed between the magnets. End barriers are placed on the free portions of the yoke. A thin sheet of a non-magnetic material is folded around the magnets and the spacers, covering the entire length of the rotor, including the barriers. An air tight membrane is placed on the outside of the sheet and sealed to the ends of the yoke so that the membrane and the yoke together form an air tight enclosure. A vacuum is applied to the air tight enclosure between the membrane and the yoke. Resin is infused into the air tight enclosure and set.

Abstract: The present invention provides a power converter that can be used to interface a generator (4) that provides variable voltage at variable frequency to a supply network operating at nominally fixed voltage and nominally fixed frequency and including features that allow the power converter to remain connected to the supply network and retain control during supply network fault and transient conditions. The power converter includes a generator bridge (10) electrically connected to the stator of the generator (4) and a network bridge (14). A dc link (12) is connected between the generator bridge (10) and the network bridge (14). A filter (16) having network terminals is connected between the network bridge (14) and the supply network. A first controller (18) is provided for controlling the operation of the semiconductor power switching devices of the generator bridge (14). Similarly, a second controller (46) is provided for controlling the operation of the semiconductor power switching devices of the network bridge (14).

Abstract: A method for the improvement of wind turbine rotor efficiency blades of a wind turbine rotor with serrated trailing edges each having a plurality of span-wise, periodic indentations, in the form of saw teeth having approximately 60 degrees included angles between adjacent vertices. The efficiency of an existing wind turbine rotor is improved by the attachment of an apparatus to at least part of the trailing edge of the wind turbine blades, the apparatus being in the form of a serrated panel that is fixed to the surface of the blade and has the serrations extending into the airflow behind the trailing edge of the existing blade. The efficiency of a new wind turbine blade is improved by manufacturing the blade with serrations of at least part of the trailing edge of the wind turbine blade.

Abstract: A method of controlling a plurality of power converters 1a, 1b and 1c can be used to interface to a supply network, ac busbar etc. Each power converter includes a network bridge 14 operating in accordance with a pulse width modulation (PWM) strategy having the same switching period and which causes at least one unwanted harmonic in the supply network voltage. The method includes the step of providing the switching period of the PWM strategy of each network bridge with a different time offset relative to a time datum such that the at least one unwanted harmonic in the supply network voltage is at least partially cancelled. Two alternative ways of providing the time offset are described.
