摘　　要：针对应用传统方法整定后动作延时较大的问题,提出基于改进蚁群算法的复杂电网继电保护自动整定方法。将复杂电网继电保护整定问题转化为非线性整数规划问题,构建一个以反时限过流保护动作时间最小为目标的自动整定模型,采用自适应思想改进蚁群算法后形成自适应最大最小蚁群算法,求解模型得到最佳整定方案。结果表明,应用设计方法后继电保护整定动作时间为0.464 s,电网可以快速恢复正常运行状态。Aiming at the problem of large action delay after using traditional methods for setting,a complex power grid relay protection automatic setting method based on improved ant colony algorithm is proposed.The complex power grid relay protection seting problem is transformed into a nonlinear integer programming problem,and an automatic setting model is constructed with the goal of minimizing the action time of inverse time overcurrent protection.The ant colony algorithm is improved with adaptive thinking to form an adaptive maximum minimum ant colony algorithm,and the model is solved to obtain the optimal setting scheme.The results show that after applying the design method,the setting action time of the relay protection is 0.464 s,and the power grid can quickly restore normal operation.
