摘　　要：为提升中压配电网极限线损计算的准确性,提出一种基于迭代拟合算法的中压配电网极限线损计算方法.该方法首先拟合出变压器高压侧的极限负荷曲线,进而迭代拟合出各上级分段线路的极限负荷曲线,求出相应形状系数的最大值,最终得出最大的线损值.最后进行了实例验证,验证结果很好的证明了该计算方法的准确性、有效性和实用性.To improve the precision of ultimate line loss calculation of mid-voltage distribution network, a novel ultimate line loss calculation method of mid-voltage distribution network based on iterative fitting algorithm was proposed.Firstly, the ultimate load curve on the transformer high-voltage side was fitted; Secondly, the ultimate load curves of each superior sectionalized line was iterated and fitted; then, shape coefficients of the above ultimate load curves were worked out; lastly, the ultimate line loss of the mid-voltage distribution network was worked out. This paper also gave an example for algorithm validity. The analytical results of the example well proved the effectiveness, accuracy and practicability of the proposed iterative fitting algorithm.
