中文摘要:

前推回代潮流算法计算速度快,收敛性好,特别适应于辐射状的配电网潮流计算；但是针对配电网故障潮流的计算却少有研究。本文针对配电网故障情况下,分析了前推回代潮流算法的计算原理,通过构建迭代过程的数学模型,提出了此算法的收敛判据；并且针对配电网故障潮流不收敛的原因,通过添加松弛因子,改变其不收敛的现象。通过在MATLAB进行数据仿真,验证了此算法的有效性和精确性。

英文摘要:

The forward and backward generation power flow algorithm has the advantages of fast calculation and good convergence. It is especially suitable for the power flow calculation of radial distribution network, but there are few studies about the calculation of distribution network fault flow. the calculation principle of forward backward power flow algorithm is analyzed and the mathematical model of the iterative process is constructed for the fault distribution network. The convergence criterion of the algorithm is proposed and the phenomenon of non convergence is changed by adding relaxation factor. The validity and accuracy of the algorithm are verified by data simulation in MATLAB.
