Powerformer, en generator som byggdes av kablar kunde inte bli Införandet av den nya generatorn Powerformer (framtagen av ABB) gör dessutom att man kan leda elen direkt ut på nätet som medför lägre driftkostnader och Vi har ocksa haft nytta av abb:s arkiv i Vasteras och Vattenfalls arkiv i Racksta, dar Denna powerformer skul- le ersatta en generator fran 1958 och mojligheten har tre aggregat och där aggregat 1, den så kallade Powerformer, nu ABB förbättrar styrningen av vattenkraftverk som genererar över 1 ABB, kan förväntas bedriva forskning och utveckling i större omfattning, men det är kompetenscentra för elkraftteknik samt ny generatorteknik (Powerformer).

ABB is the largest electrical equipment manufacturing company in the world. They are pioneers in the field of AC motor drives with the highest sale of more than 250,000 units last year. They are pioneers in the field of Automation and Control of Paper, Cement and Steel Industries processes. ABB is claiming a breakthrough with what it describes as the "world's first high-voltage generator". Called the PowerformerTM, it was launched in Zurich on 25 February and is said to be the first generator able to supply electricity directly to the high voltage network without the need for intervening transformers. ABB’s Powerformer high voltage generator will be installed at Vattenfall’s Porsi plant, it was announced recently. 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).

Friday 16/10, 10.15-12.00 Licentiate seminar in room E:1406 On the analysis and control of a split pole induction machine Patrice Lesage External reviewer: Professor Alan G. Jack, University of Newcastle upon Tyne, Great Britain. Powerformer windings on the other hand form uniform electric field. This means that the insulating material is evenly loaded and used in an optimal way. Secondly Powerformer cable for an electric field strength of 10 kV / mm, which should be compared with the 3kV/mm is designed to be able to manage today’s generator windings (Figure (5)). electric power generator, the Powerformer introduced by ABB Corporate Research Sweden and ABB Generation Sweden (ABB-Power-Generation 1998). Its introduction marked a substantial shift in the way that electrical power generation is viewed. Unlike conventional power generators, which … ABB is currently testing a 500 kw prototype.

In 1998, Eskilstuna Energi och Miljö awarded ABB Generation a contract for the second Powerformer, to be installed in a new CHP plant in Eskilstuna in central Sweden. This turbo machine has a rated voltage of 136 kV, a rated capacity of 42 MVA and a rated speed of 3 000 rpm. It will be in commercial operation at the end of 2000. 20 October 1999 Going back to the basic principles of Maxwell's equations, ABB has developed Dryformer, a dry power transformer based on cylindrical windings. Following on from the development of the revolutionary Powerformer, ABB has developed a new transformer, Dryformer. WindformerTMis a new wind power system, developed by ABB for wind farms situated offshore and in coastal areas. WTGs with Windformer have a high output of typically 3 to 5 MW. This generator power rating has a number of advantages.
