To combine the advantages of both Tabu search (TS) and evolutionary algo- rithms (EAs), a new niche-based evolutionary Tabu search algo- rithm (named NETS) is presented to solve this optimization prob- lem. Moreover, in two cases of power networks, comparisons be- tween NETS and two published algorithms are given. Experimen- tal results show the expression of the objective function for pro- tection relay setting is feasible and reasonable, and the proposed algorithm NETS exhibits a good performance. 关 键 词：禁忌搜索算法 进化算法 继电保护 TABU搜索算法 中电网 函数优化问题 过电流继电器 保护设置
