本文提出了一种新的、全面的可控串联补偿器（TCSC）潮流模型。在该模型中，状态变量是TCSC的触发角，其与整个网络的节点电压幅值和角度结合在单个参考系中，用于通过牛顿-拉夫森方法的统一迭代解。与公开文献中可用的TCSC模型不同，该模型考虑了TCSC在部分传导和完全传导操作模式下存在的回路电流。此外，该模型采取适当的照顾TCSC基频阻抗所表现出的谐振点。Newton-Raphson算法具有二次或近二次收敛特性，与网络的大小和TCSC设备的数量无关。
A new and comprehensive load flow model for the thyristor controlled series compensator (TCSC) is presented in this paper. In this model the state variable is the TCSC's firing angle, which is combined with the nodal voltage magnitudes and angles of the entire network in a single frame-of-reference for a unified iterative solution through a Newton-Raphson method. Unlike TCSC models available in the open literature, this model takes account of the loop current that exists in the TCSC under both partial and full conduction operating modes. Also, the model takes proper care of the resonant points exhibited by the TCSC fundamental frequency impedance. The Newton-Raphson algorithm exhibits quadratic or near-quadratic convergence characteristics, regardless of the size of the network and the number of TCSC devices.
