摘　　要：可控串联电容器(Thyristor Controlled Series Capacitor,TCSC)能够有效地提高线路的输送功率,影响系统的无功功率分布,提高系统的电压稳定性。本文采用重复潮流(Repeated Power Flow,RPF)法求解含有TCSC的可用输电能力,并应用脚本语言Python对仿真软件PSS/E进行二次编程来实现。通过对WSCC-9节点和IEEE-30节点系统进行仿真计算,结果表明TCSC有助于提高系统的可用输电能力,同时也验证了本文所采用模型及方法的正确性和有效性。Thyristor Controlled Series Capacitor（TCSC） can effectively increase the transmission line power, affect the distribution of reactive power and improve the voltage stability of the system. In this paper, the RPF method is used to calculate available transfer capability with TCSC. To implement the algorithm, Python which is a script language is applied to develop advanced applications based on PSS/E. The effectiveness of the presented model and approach is supported by the tests on the WSCC-9 bus and IEEE-30 bus systems,and the improvement of ATC using TCSC is demonstrated with the simulation results.
