摘　　要：针对含有高密度采集数据的DG中压配电网线损计算,提出了一种配电网连续线损计算方法,旨在提高传统线损计算的精度。该方法充分利用调度侧和DG侧的高密度采集数据,将供电功率按功率分配给各个负荷节点,计算实时潮流,从而获得更可靠的线损值。在IEEE 17节点配电系统中验证了该方法的有效性和准确性。For the line loss calculation of medium-voltage distribution networks containing DGs with high-density collection data,a continuous line loss calculation method for the distribution network was proposed,aiming at improving the accuracy compared with the traditional line loss calculation method.The proposed method makes full use of the high-density collection data on the dispatch side and DG side,distributing the supply power to each load node by power to calculate real-time power flow,thus obtaining a more credible line loss value.The effectiveness and accuracy of the proposed method were verified in the IEEE 17-node distribution system.
