Beschreibung
Zusammenfassung:	The invention discloses a harmonic generation device and a control method based on a recursive discrete Fourier transform. The harmonic generation device based on the recursive discrete Fourier transform comprises a fundamental wave realization module, a harmonic generation module, a three-phase series-coupled transformer group and a three-phase load. The harmonic generation module extracts the amplitude of the harmonic voltage on the load side of the power network simulator efficiently through the recursive discrete Fourier transform, outputs a given reference value of the amplitude closed-loop control of the harmonic voltage, and thereby performs the harmonic amplitude closed-loop control. The invention discloses a harmonic generation device and a control method based on the recursive discrete Fourier transform, which not only ensures the harmonic generation precision of a power network simulator, but also improves the dynamic performance of the power network simulator, and better meets the test requirement
