Abstract Electrical energy revolutionary changed human life Nowadays because of economical and environmental problems men have started use of renewable energies instead of fossil fuel sources In this wind as new energy source which can be easily used has become increasingly important In order to change the wind energy to electrical energy different methods have been applied in which the induction generator with direct connection to network is the most popular Compared to synchronous machines the induction machines are low cost and do not need separate dc source and brushes A problem with in the induction machines is the significant consumption of reactive power which can be provided by capacitors equipped with power electronics devices When such a generator operates separated from the power grid proper adjusting the capacitor value affects the generator output voltage significantly This research presents a brief study on the new energy sources wind farms and power electronics in distribution levels Then the behavior of an induction generator while separating from grid has been analyzed and a new equivalent model has been proposed Based on the proposed model strategies for regulating voltage using D Statcom is presented and modified to minimize sudden voltage changes Moreover a generator frequency control method is presented and its frequency response is improved using scalar electric drive technique pdfMachine A pdf writer that produces quality PDF files with ease Produce quality PDF files in seconds and preserve the integrity of your original documents Compatible across nearly all Windows platforms simply open the document you want to convert click print select the Broadgun pdfMachine printer and that s it Get yours now
