本文对不平衡配电系统中多相潮流方法的主要收敛特性进行了评估。分析了两种广泛使用的解决不平衡潮流的方法：基于牛顿-拉夫逊（NR）的方法和基于后向前扫（BFS）的方法。 BFS方法和NR方法的局限性和鲁棒性在以下方面进行测试：（i）X/R比的变化，（ii）负载增加到收敛极限，（iii）负载模型影响（ZIP模型），以及（iv）电压调节器建模影响。文献中提出的一些模型已被实施和测试。测试在 IEEE 34 和 IEEE 123 系统上进行。还提出了分析解释。
This paper presents an evaluation of the main convergence characteristics of multiphase power flow methods in unbalanced distribution systems. Two widely used methods for solving unbalanced power flows are analyzed: methods based on Newton–Raphson (NR) and methods based on backward forward sweep (BFS). The limits and robustness of the BFS method and NR method are tested in the following aspects: (i) variation of the X/R ratio, (ii) load’s increase up to the convergence limit, (iii) load model impacts (ZIP model), and (iv) voltage regulators modeling impacts. Some models presented in the literature were implemented and tested. Tests are performed on the IEEE 34 and IEEE 123 systems. Analytical explanations are also presented.
