The Impact on the Voltage Fluctuation of Wind Power Integrated Separately in Chongqing Distribution Network

Abstract:

Recently, the development of Chinese wind power generation has formally entered the strategic transformation stage with the combination of large-scale integrated exploitation and distributed access exploitation. It is suitable to adopt distribution access mode due to the characteristics of Chongqings planning wind farm including small generation capacity and distributed location. However, considering that most of planning wind farms are located in the mountain area of northeast and southeast Chongqing with the large-scale geographic area and small load request and the distribution networks are relatively weak, there may be remarkable effect on quality of electric energy even though the distribution access mode is adopted. In this paper, aiming at the voltage fluctuation of access point, the relationships among variables affecting the voltage fluctuation is analyzed, then taking two planning wind farms in northeast and southeast Chongqing respectively as examples, the effects of voltage fluctuation caused by different access points are calculated and analyzed in order to get the allowed maximum capacity of wind farms fitting national standards. In the end, the proposals relevant to the development of wind power and contribution of distribution network are submitted according to the case results.
