摘　　要：随着非线性负荷使用比重越来越大,在配电网中易产生谐波,造成谐波污染。因此,一种准确、快速的谐波分析方法受到关注。该文提出一种基于前/后向扫频技术的非迭代谐波潮流(HLF)方法,考虑线性负载和电容器组对配电网谐波发射的影响的同时进行谐波分析。考虑线性负载效应,将所提出的方法用于电容器补偿的IEEE 69总线配电网络的网络重构中。结果表明,该方法比常规的HLF方法的优化速度快了18.6%。此外,还表明线性负载建模方法会影响重构结果。With the increasing proportion of non-linear loads,harmonics are easily generated in the distribution network,causing harmonic pollution.Therefore,increasing attention is paid to an accurate and fast harmonic analysis method.In this paper,a non-iterative harmonic power flow(HLF)method based on forward/backward frequency sweeping technology is proposed,which takes into account the impact of linear loads and capacitor banks on the harmonic emission of the distribution network and simultaneously conducts harmonic analysis.Considering the linear load effect,the proposed method is used in the network reconstruction of the capacitorcompensated IEEE 69 bus distribution network.The results show that this method is 18.6%faster than the conventional HLF method.In addition,it also shows that the linear load modeling method will affect the reconstruction results.
