Abstract

Abstract Large-capacity long-distance offshore wind farm adopts high-voltage AC submarine cable outgoing line and collecting system. Due to the high capacitance of submarine cable to ground, the harmonic resonance problem of wind farm is increasingly prominent. First of all, through the actual measurement of the wind turbine yaw system exiting due to the 5th harmonic resonance when the wind turbine is shut down in an offshore wind farm along Jiangsu coast, and the analysis of harmonic current and impedance frequency, the reason of resonance is further analyzed. Finally, the ETAP simulation software is used to analyze the measured data, and then several kinds of causes of offshore wind power resonance are obtained, and the corresponding improvement measures are put forward.
