The paper presents measurements of complex harmonic current of two modern wind turbines. The complex current has been obtained with a 5 Hz resolution up to 2.8 kHz. The distribution of complex current has been studied in the complex plane. Distinction has been made between low-order integer harmonics, interharmonics and high-order harmonics: low-order integer harmonics are distributed around a center off set from the origin of the complex plane; interharmonics and high-order harmonics are distributed around the origin with a uniformly distributed phase-angle.
