摘　　要：针对如何确定可控串联电容器(Thyristor Controlled Series Capacitor,TCSC)的安装位置和容量,以最大限度地提高系统可用输电能力(Available transfer capability,ATC),建立了用于提高输电能力的TCSC优化配置数学模型,对免疫算法中抗体按亲和度的排序法进行了改进,使抗体种群向补偿量减小的方向进化,可以节省补偿容量。利用改进后的免疫算法对模型进行求解,该方法能够同时确定TCSC的最佳安装地点和最优补偿度,且对加装多个TCSC时的情况也同样适用。最后对IEEE30节点系统进行计算,并应用逐条支路安装测试的方法对结果加以验证,表明所提方法是合理且有效的。The purpose of this paper is to determine the installation site and capacity of Thyristor Controlled Series Capacitor （TCSC） which is used to improve available transfer capability （ATC）. The mathematic model of TCSCs＇ allocation for enhancing ATC is set up, and the antibodies＇ ranking method based on the affinity degree of the antibody to the antigen is improved in order to make the quantity of the compensation as smaller as possible. The improved immune algorithm is used to solve the model. The method can determine the optimal location and the desired compensation degree at the same time, and is applicable for the case of containing more TCSC devices. By applying the proposed method to the IEEE30-bus system, and through the test of installing TCSC on each branch individually in succession, the numerical results illustrate the feasibility and validity of the method.
