Asynchronous Grid Connection of a Cage Induction Generator Excited by a Power Electronic Converter

This article presents an analysis of grid connection excited induction generator, where inrush current is significantly reduced and voltage drop in the local eliminated. In proposed method, generator to done at moment when vector equals vector, but frequency differs from frequency. Excitation provided by a power electronic converter, which rated only on reactive generator. Moreover, connected grid, converter satisfies demand according requirements distribution system operator. The simulation laboratory tests were conducted with 7.5 kW
