摘　　要：针对电力现场人工稽查危险性高、准确率低的问题,提出基于移动作业的电力现场异常智能化稽查方法。采集电力电场周围的电流变化数据,根据安倍定律得出电缆内外部形成的环形闭合电流。建立空间三点坐标系,计算电缆在三个方向上闭合电流值,若电流值超出既定阈值,判定周围存在磁场影响。模拟矩形的稽查空间体,在该空间体中计算待稽查点间位置关系,将位置阈值代入到异常判定矩阵中,输出异常信号位置。实验结果表明,所提方法可充分利用电力现场的暂态数据,稽查结果符合现场实际情况,具有适用性强、稽查覆盖范围广、准确率高的优势。Aiming at the problems of high risk and low accuracy of manual inspection in power field,an intelligent inspection method of power field anomaly based on mobile operation is proposed.It collects the current change data around the electric field,and ob-tains the ring closing current formed inside and outside the cable according to Abe's law.It establishes a spatial three-point coordi-nate system to calculate the closing current value of the cable in three directions.If the current value exceeds the established threshold,it is determined that there is a magnetic field around.It simulates the rectangular inspection space,calculates the posi-tion relationship between the points to be inspected in the space,substitutes the position threshold into the anomaly determination matrix,and outputs the abnormal signal position.The experimental results show that the proposed method can make full use of the transient data of the power field,and the audit results are in line with the actual situation of the field.It has the advantages of strong applicability,wide audit coverage and high accuracy.
