풍력발전이 연계된 배전선로 전압 및 과도상태 해석

Abstract

The use of the wind energy resource is a rapidly growing area world-wide. The number of installed units is continuously increasing, and therefore, it is important to respect and to deal with the impact of wind power generation system. From the view of an electric grid utility, there is a major problem with the impact of the wind system on the voltage of the electric grid, to which a turbine is connected. In this paper, it is investigated the voltage impact and transient state analysis on distribution line, with which wind power generation system is connected. Connections of wind power system usually occur to voltage drop due to reactive power absorption and sometime result in higher than nominal voltage.Keywards : 풍력발전시스템(wind power generation system), 전압영향(voltage impact), 과도상태 해석(transient state analysis), 풍력시스템연계(Connection of wind power system)
