摘　　要：文章提出了基于前推回代法的三相功率不平衡潮流计算方法。该方法不需要对线路的自阻抗和互阻抗进行对称分量分解,既能避免序阻抗中的耦合因子,又能简化潮流计算步骤。在此结果基础上,利用对称分量分解得出各节点的正负零序电压和不平衡度,为园区的电能质量治理提供了依据。使用IEEE33节点配电网数据进行分析,结果显示该方法具有优越性。此外,该方法在园区配电网监控平台中得到了实际应用。The article proposes a three-phase power imbalance flow calculation method based on the forward backward substitution method.This method does not require symmetric component decomposition of the self impedance and mutual impedance of the line,which can avoid coupling factors in the sequence impedance and simplify the power flow calculation steps.Based on this result,the positive and negative zero sequence voltages and unbalance degree of each node were obtained using symmetric component decomposition,providing a basis for the power quality management of the park.The analysis using IEEE33 node distribution network data shows that this method has superiority.In addition,this method has been practically applied in the monitoring platform of the distribution network in the park.
