To solve the high frequency resonance problem of a wind field regional system with a chained static var generator (SVG), an SVG harmonic impedance model including phase-locked, power outer and current inner loops is first established by the harmonic linearization method. An impedance analysis method is applied to the unloaded line in the wind field area to analyze the effect on the stability of the SVG. This reveals a high frequency resonance mechanism of the wind field regional system. Then, to suppress the high frequency resonance of the system, an SVG-BASED high frequency resonance suppression strategy based on additional band stop filter is proposed in the voltage feedforward compensator. The equivalent impedance of the SVG side in the middle and high frequency band is reconstructed to ensure that the positive damping state of the system is in the band. The influence of the center frequency and damping coefficient of the band stop filter on the phase margin of the system is discussed. Finally, a simulation model of the wind field area system containing chained SVG is used to verify the correctness of the theoretical analysis and the effectiveness of the proposed suppression strategy.
