摘　　要：给出一个具有多控制功能的静止同步串联补偿器(SSSC)电压源模型.在包括串联变压器阻抗以及线路充电容纳的情况下,该模型能保持网络导纳矩阵的原始结构及对称性,从而雅可比矩阵可保持分块对角属性及稀疏性.考虑了SSSC可能的运行极限,在处理极限前后牛顿拉夫逊表达式保持相同的结构,提高了求解效率.以IEEE-57I、EEE-118及IEEE-300母线系统为例,验证了本文模型的收敛性及SSSC的多控制功能,展示了SSSC运行极限对潮流解及收敛性的影响.This paper presented a modeling of the static synchronous series compensator （SSSC） with multi-control modes for power flow analysis. In this model, the impedance of the series coupling transformer and the line charging susceptance are all included. It is proved that the original structure and sym metry of the admittance matrix can still be kept, and thus the Jacobian matrix can keep the block diagonal properties and a sparsity technique can be applied. Furthermore, the operating limits of SSSC can be systematically enforced, and the formulation of the Newton-Raphson algorithm with the limits enforcement has exactly the same structure as that of the Newton-Raphson algorithm without it. The numerical results based on the IEEE-57, IEEE-118, and IEEE-300 buses system were used to demonstrate the effectiveness and performance of the SSSC model.
