摘要(Abstract)：

针对高温超导故障限流器(high temperature superconductor-fault current limiter,HTS-FCL)的全网优化配置问题,提出了一种基于免疫算法的高温超导故障限流器Pareto多目标优化配置新方法。该方法综合考虑了限流器的成本和限流效果这2个优化目标。首先介绍了HTS-FCL的基本结构和原理,分析了安装高温超导故障限流器对原系统自阻抗的影响,提出了一种基于短路电流变化率的灵敏度计算方法,该方法可以缩小搜索空间,提高算法效率。然后分别建立了限流器成本评价子函数、限流效果评价子函数和多目标评价函数,制定了基于免疫算法的多目标Pareto优化算法流程,并在传统免疫算法的基础上提出了一种改进型的等成本倒位算子,通过仿真验证表明该算子较常规的免疫算法,能更好地收敛到最优解。最后以IEEE 39标准节点系统为例,实现了HTS-FCL的全网优化配置,验证了新方法的有效性,并求得了在综合考虑限流器成本和限流效果下的Pareto最优解集,设计者可以根据自己的意愿和实际情况在所求得的Pareto最优解集中选择合适的最优方案。
