摘要: This paper presents harmonic measurements from three individual wind turbines (2 and 2.5MW size). Both harmonics interharmonics have been evaluated, especially with reference to variations in the active-power production. The overall spectra reveal that, emission components may occur at any frequency not only odd harmonics. Interharmonics even emitted are relatively high. Individual depend on power production dierent ways: characteristic independent of power; show a strong correlation other interharmonic present various patterns. It is concluded that factor determining current energy conversion system.
