20㎿의 풍력발전단지의 실측 데이터 기반한 전력품질 분석 평가

Wind power plants must provide the power quality required, similar to that provided by the conventional power plants, to ensure the stability and reliability of the power system it is connected to. Although many operational aspects affect wind power plant operation, this paper, we focus on power quality. Since a wind power plant is connected to the grid, it is very important to understand the sources of disturbances that affect the power quality. This paper performs power quality analysis based on actual data of wind power plants. Especially, it has analysed voltage variation, power factor, harmonics in comparison with distributed generation network interconnection technology standards. In this paper, when the power amount was below 2㎿, there was a deterioration in power quality for power factor, voltage variation and harmonics.
