摘要(Abstract)：

交直流混合输电系统的潮流计算是静态安全分析以及暂态稳定、电压稳定、小干扰特征值等分析计算的前提和基础。深入解析和理解电力系统广泛应用的商业计算软件中高压直流输电系统的数学模型、混合系统潮流求解算法,并掌握影响收敛性的相关因素,对提高大电网分析人员的计算效率具有重要意义。首先推导了国内广泛应用的BPA潮流计算软件中,双端高压直流输电系统的准稳态模型;解析了交直流潮流交替求解算法流程;通过对一双端高压直流输电系统的潮流解轨迹的计算和分析,揭示了交直流系统的相互影响特性;总结了决定特高压直流运行状态和交直流潮流收敛特性的影响因素。

关键词(KeyWords)： 特高压直流输电;准稳态模型;潮流算法;收敛特性
