摘要
BPA和PSS/E是目前国内应用较为普遍的短路电流计算程序,针对使用中常常发现两程序计算结果存在较大差异的情况,利用PSS/E程序灵活的初值条件设置和可逐步人为干预的特点,分析研究了它们在基于潮流和基于初值条件下的对称故障、非对称故障短路电流计算结果差异的原因。研究结论可为制定统一规范的互联电网短路电流计算条件提供依据。
BPA and PSS/E are both short-circuit current calculation softwares widely used in China, however, their calculation results are quite different, The reasons for the symmetrical and unsymmetrical short-circuit calculation result difference between the two softwares are analyzed,with consideration of PSS/E＇s features of flexible initial setting and convenitent adjustment. The analysis involves power flow-based fault calcuation and initial condition-based calculation. The conclusions drawn from the analysis are valuable for developing uniform short-circuit current calculation eondition for interconnected grids.
