Technical Supervision of Harmonic and Typical Accident Analysis in Wind Farm

Abstract

The large-scale access of wind power generation has brought an unprecedented impact on the power system, especially on the power quality. Harmonics will inevitably be generated by wind farms during operation and affect the normal and safe power supply and stable operation of power system, endanger personal safety and reduce economic efficiency. In this paper, the necessity of harmonic technical supervision of wind farm is emphasized, and the the contents of harmonic technical supervision is introduced. In addition, a typical harmonic accident in a wind farm is analysed to illustrate how harmonic causes losses to wind farm and power system, and some suggestions are put forward for the wind farms.
