Powerformer is a high-voltage generator; the limitation in its rated voltage is set solely by the AC Power cable and the cable accessories (terminations and joints) used in its stator winding. This means that Powerformer of voltage ratings up to 400 kV can be realized, although has not been proved yet.

N2 - Powerformer(R), a new high-voltage generator, was presented by ABB. It offers a direct connection to the power network without the need for a step-up transformer. In a sense, Powerformer incorporates into one unit the functions of both the conventional generator and the step-up transformer.

Powerformer™, en helt ny typ av generator som utvecklats av ABB, har valts för Eskilstunas nya kraftvärmeverk. Detta är den första kommersi-ella beställningen av en Powerformer till värmekraftsektorn. Generatorn har märkeffekten 42 MVA vid 136 kV och 3000 r/min. Den ansluts direkt Powerformer Den första generatorn enligt den nya teknologin har redan framg ångsrikt tes-tats i fabrik .

The source generator has to deliver a 50 kA current at 500 kV for the specified time into the HPM device. Powerformer/sup TM/-the prototype and beyond Abstract: The general concept of Powerformer/sup TM/, a high voltage generator connected directly to the grid, is described. By using high-voltage cable technology it is possible to confine the electrical field to inside the winding and reach high voltage levels on the generator terminals. @misc{0468df1f-c1ca-4bf7-ba33-35119d2a7a27, author = {Leijon, M. and Lindahl, Sture and Gertmar, Lars}, language = {eng}, title = {High Voltage Cables in a new Class Request PDF | Powerformer and its recent development | A completely new class of generators which are able to deliver electric power at transmission line voltage level directly - Powerformer (POP sample powerformer. Also a comparison between the results obtained by FEM as well as analytical formulas has been made.

Abstract: Powerformer(R), a new high-voltage generator, was presented by ABB. It offers a direct connection to the power network without the need for a step-up transformer. In a sense, Powerformer incorporates into one unit the functions of both the conventional generator and the step-up transformer. A new class of generators ,powerformer ,which are able to deliver electric power directly at transmission voltage levels..This is achived by changing from traditional stator windings with rectangular conductors to windings with circular conductors alstom Power has received a new order to supply a high voltage Powerformer generator to Swedish utility Fortum Kraft, which owns 40 hydro power plants in central Sweden. The Powerformer — which can generate at high voltage, feeding electricity directly into the transmission network without the need for a step-up transformer — will be installed at Höljebro hydro power plant on the Ljusnan river. The Powerformer is a new type of generator that can be connected directly to the grid, without the need for a step up transformer (see IWP&DC, April 1998, pp34&35). The new generator will be rated at 155kV, 75MVA. It will be installed at Porsi on Sweden’s Lule river (shown above), where it will replace one of the existing generators.

The source generator has to deliver a 50 kA current … The Powerformer is able to maintain an overload in its stator windings for a longer period than a conventional generator. This means that Powerformer may provide reactive support for an extended period of time compared to a conventional generator. The benefits of this overload capability in improving voltage For a synchronous electric generator an earth fault detection or protection circuit is provided using extracted (35A, 35B, 35C) third order harmonic currents (Ia3, Ib3, Ic3) in the phase windings (1A, 1B, 1C) at locations at the neutral point (N, 5). From the third order harmonic currents, directional criteria (Da, Db, Dc) for each phase winding are calculated (35) indicating the relative https://www.irjet.net/archives/V3/i11/IRJET-V3I11171.pdf @misc{0468df1f-c1ca-4bf7-ba33-35119d2a7a27, author = {Leijon, M. and Lindahl, Sture and Gertmar, Lars}, language = {eng}, title = {High Voltage Cables in a new Class Powerformer is a new kind of high-voltage generator, which can be connected with power grid directly.
