Description
Summary:This paper presents measurements of harmonic current emissions up till few kHz from four different wind parks in northern Sweden, all equipped with modern power-electronics converters. Measurements have been performed with 10-minute time resolution between one and several weeks. The measurement results are presented in different ways, including a method to show the variations in the harmonic emissions with time. The results show that there exists different dominating harmonics in different wind turbines and that the magnitudes of the individual frequency components vary strongly with time. Each turbine however shows a broadband component with superimposed narrowband components. Godkänd; 2012; 20121101 (kaiyan)
