| 20090218820 | Power Converter Arrangement and Method - A power converter arrangement for connecting an induction generator to an electric power network comprises a first path provided for transferring electric power from the induction generator to the electric power network during a first operation condition, and a second path provided for transferring electric power from the induction generator to the electric power network during a second operation condition, where the first path includes an AC-AC converter and the second path includes a switch. A capacitor arrangement is interconnected between the induction generator and the first and second paths and a first AC reactor device is interconnected between the capacitor arrangement and the first and second paths, where the capacitor arrangement is provided for compensating for a magnetization current of the induction generator. | 09-03-2009 |
| 20100292852 | Wind mill power flow control with dump load and power converter - A wind mill apparatus for generating electric power to a grid point of an electric network. The apparatus includes a wind rotor, an electric generator operatively connected to the wind rotor, and an electric multiphase ac link operatively connecting the generator to the grid point. The ac link includes a first current path including a switchgear, a second current path including a dc link including a first converter operatively connected to the generator, a second converter operatively connected to the grid point, and a capacitor operatively connected between the conductors of the dc link. The ac link further includes a connectable multiphase dump load for blocking during a fault condition on the network the reactive power flow in the ac link, yet providing a reduced transfer of active power. | 11-18-2010 |

| 20110151909 | TAKING CONTROL OF SUBSCRIBER TERMINAL - Taking control of a subscriber terminal is disclosed. An apparatus comprises a processor configured to cause the apparatus: to control a stand-alone base station so that an emulated cell of a cellular radio system is formed by transmitting a control channel with information of a real cell and with such transmission power that a subscriber terminal having an ongoing connection with a serving cell base station is caused to measure reception of the stand-alone base station as being better than reception of the serving cell base station; and to control the stand-alone base station to perform cell reselection with the subscriber terminal so that the ongoing radio connection with the serving cell base station is transferred to continue with the stand-alone base station. | 06-23-2011 |
