However the inter turbine grid causes small resonances which varies with the wind turbines position in the inter-turbine grid. This little resonance has less potential to amplify harmonic components but grid codes like IEEE-519 standard are more restrictive with the high order harmonics. To avoid as far as possible the harmonic amplification in normal operation due to the resonance of the transmission system one good option seems to choose a configuration which the resonance frequency of the transmission system coincides with one of the frequencies that the step up transformer does not allow to transmit Fig. 9. 6.
