摘要: In this paper, harmonic voltage and current measurements performed at the point of common coupling (PCC) a commercially operated wind farm comprising 40 variable-speed turbines are analyzed, their most important characteristics presented. Important issues under consideration measured spectrum, effect application grouping calculation method according to IEC 61000-4-7, interharmonic problems, probability distribution magnitude. addition, an investigation separation grid contributions distortion PCC is included. Finally, dependence emission on output power addressed.
