摘　　要：风电接入系统会产生谐波污染,对于大规模集中式风电场,须考虑其谐波所产生的叠加效应。文中先对风电场谐波产生原因进行了分析,再结合工程实例,讨论两种叠加算法所计算得到的电网公共连接(PCC)点处的谐波电流大小,且能更好地为建设风电场提供可靠依据。Harmonic pollution will be generated when wind power is integrated to power system. For large-scale centralized wind farm, superposition effect generated by harmonic must be considered. This paper analyzed cause of harmonic generated by wind power. Combined with project cases, harmonic current of power grid common connection point were calculated by two kinds of superposition algorithm. It can provide a reliable basis for the construction of wind power.
