太阳能光伏电站并网对山西局部电网的影响

摘要

指出随着传统能源继续紧缺，新能源的发展任务更显日益紧迫，光伏发电作为一种新能源，已成为常规能源一种有效补充。详细分析了光伏电站并网对电网引起的谐波、电压波动、电压不平衡度等影响，更好地指导并网光伏系统的健康发展。%With the shortage of traditional energy sources, it is more emergent to develop new energy. Solar energy, as a kind of new resource,has become an effective supplyment for traditional energy. This paper analysed the influences of the photovoltaic grid-connection on harmonic wave,voltage fluctuation and the imbalance of three-phase voltage in detail,which provides guidance for grid-connected photovoltaic system to be implemented soundly.
