【摘要】 通过观察ＰＱ分解法对几个典型系统在不同参数下的潮流计算结果，本文详细分析了形成系数矩阵Ｂ′和Ｂ′时忽略或考虑支路电阻、对地导纳和理想变压器非标准变比对收敛性、收敛速度的影响，讨论了Ｐ－θ迭代过程中节点电压不同取值情况下的收敛特性。计算结果表明，形成Ｂ′和Ｂ″时考虑或忽略支路电阻是影响ＰＱ分解法收敛性的主要因素。更多还原

【Abstract】 According to the results of the Fast Decoupled Load Flow (FDLF) solution for several typical powersystems in either well-behaved or ill-conditioned state, it isanalyzed that how the convergence property of FDLF is affected by the several parameters, such as line series resistances, shunt reactances and transformer tappings, in theformulation of matrixes B’ and B’. The effect of the convergence property for setting voltage values in P-θ iteration isalso discussed. The results indicate that among the parameters considered in forming B’ and B’ the line series resistanceplays the most significant role in the convergence of theFDLF solution.更多还原
