Powerformer med en effekt på 11 MVA, 45 kV och 600 varv/min tas i drift under våren 1998 i Porjus vattenkraftcentrum. Nyckelfördelar med den nya konstruktionen Med det nya systemet kan olika delar av konstruktionen separeras och behand- 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. 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.

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.

Generate your gas on-site - to the purity level & amount Generator Source purchases new, surplus, and used generators. Good running industrial/commercial diesel or natural gas units. Fill out our short form or call 20 Apr 2001 This was also a key milestone in the brief history of Powerformer, whose the plant set a world record for generator terminal voltage, 177 kV. 15 Dec 2011 at [1]-[2] introduces a generator known as powerformer which could generate high in slots of stator as armature winding powerformers could. 30 May 2008 The Powerformer can generate electricity at voltages between 30 kV and 400 kV.

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. 1.Comparison of Powerformer TM and conventional generator [3] Powerformer TM is able to generate electricity at transmission voltage levels and can inject power directly into the transmission T1 - High Voltage Cables in a new Class of Generators - Powerformer™ AU - Leijon, M.

An issue that has permeated the development process of Powerformer is the importance of keeping safely within the limits of the ratings of the cables used and using standard components, for example for the cable joints, in Powerformer’s inventor, Mats Leijon, manager, Department of High Voltage Engineering, ABB Corporate Research, Västerås, Sweden, started pursuing the concept of a cable-wound generator stator at the beginning of the 1990s. “I’m convinced that my ideas will change the entire energy market,” he says. 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. The stator windings of the high-voltage generator make use of cable.

The other products include the Dryformer, an oil-free power transformer, and the Windformer, a new wind power generating system. 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 är en generator utvecklad av ABB på 1990-talet och slutligen lanserad 1998. Powerformern är en högspänningsgenerator och kan därför direktanslutas till elnätet utan mellanliggande transformator, vilket minskar effektförlusterna med upp till tre procent. Ansvarig för utvecklingen var Mats Leijon, idag professor vid Uppsala universitet.

Powerformer Concept Powerformer, although a new machine, it is a 3-phase AC generator with a rotor of conventional design. The difference compared with conventional generator lies in the stator windings. In Powerformer stator winding consists of high-voltage cables instead of today’s windings with a … By changing conventional generators construction leijon at [1]-[2] introduces a generator known as powerformer which could generate high voltage upper than the mentioned one. So, in power-plants with these generators, the step up transformer as well as the environmental and technical problems related to it … Powerformer is a high voltage generator, and the limitation in their rated voltage is set only by the AC. Power cable and cable accessories (terminations and joints) used in its stator winding. This means that the powerformer voltages up to 400 kV can be realized, although it has not yet been proved. Quick Links. 2020-07-01 Powerformer- A Discontinuous Innovation.
