摘　　要：对于10 kV组合互感器而言,电流失真会使输出电流的数值水平异常增大,并且长时间不恢复至常规电流状态,从而影响互感器的正常运行。为解决上述问题,设计基于鲸鱼算法的10 kV组合互感器失真电流校正方法。构建10 kV组合互感器结构模型,完善鲸鱼算法流程,基于鲸鱼算法获取失真的电流计量数值,实现组合互感器的失真特性判定,完成基于鲸鱼算法的10 kV组合互感器失真电流校正算法的设计。实验结果表明,经过设计方法对互感器失真电流进行校正处理后,可在2 min之内将失真电流恢复至与常规电流完全相同的数值状态,校正效果较好。For a 10 kV combination transformer,current distortion will cause an abnormal increase in the numerical level of the output current,and it will not return to the normal current state for a long time,thus affecting the normal operation of the transformer.To address the above issues,a distortion current correction method for 10 kV combination transformers based on the whale algorithm is designed.Construct a structural model of 10 kV combination transformer,improve the whale algorithm process,obtain distorted current measurement values based on the whale algorithm,achieve the determination of distortion characteristics of the combination transformer,and complete the design of the whale algorithm based distortion current correction algorithm for 10 kV combination transformer.The experimental results show that after correcting the distorted current of the transformer through the design method,the distorted current can be restored to the same numerical state as the conventional current within 2 minutes,and the correction effect is good.
