Impact of Wind Power Plant Operation on Voltage Quality Parameters—Example from Poland

In Poland, there has been a steady increase in the share of wind-generated energy overall balance country. However, wind power plants belong to unstable sources—the amount generated is variable time. Variable generation may cause problems with quality transmitted electricity networks. Therefore, this article presents results field tests impact Vestas V90 2 MW turbine on selected voltage parameters occurring grid. Due multifaceted influence plant grid which it connected, focuses only four parameters: value, zero and reverse asymmetry, value distortion factor. The research conducted by authors confirmed positive operation through An tested resulted decrease values both asymmetry factor (zero reverse) total THDU.
