提出了一种兼顾技术性和经济性的大电网永磁偏置型故障限流器(Permanent-magnet-biased Saturation based Fault Current Limiter,PMFCL)优化配置算法.简要介绍了PMFCL限流机理,并定义了短路电流裕量作为挑选超标节点的标准,将节点自阻抗作为节点短路电流水平的衡量指标,基于节点自阻抗增量构建了兼顾全局限流效果与经济性的PMFCL优化配置评价函数,据此提出了依据PMFCL启动条件和节点自阻抗对支路阻抗参数的灵敏度指标来缩小寻优空间的PMFCL在大电网中配置优化算法.将该算法应用于IEEE 39节点标准算例,调用MATLAB遗传算法函数完成仿真,仿真结果验证了该算法可行性及有效性。
