【摘要】：为了对输电线路带电作业的安全距离进行更准确的判定,提出了场强矢量定位方法。建立输电线路周围空间的场强计算模型,根据场强测量点处的场强矢量分量和合成场强最大值、场强传感器的测量误差,寻找测量位置的场强可能接近点坐标集,并根据数学聚类方法将坐标集划分为不同的点群。根据场强测量点的移动特征,确定一个真实接近点群中心实现准确的跟踪定位。最后通过220 k V输电线路二维场强的仿真算例分析,显示82.7%场强测量点的距离误差≤0.1 m,仅有2.75%的≥0.5 m,根据测量点的移动特征可使距离误差基本均减小至0.1 m以下。实际测试中,95%次的测试距离误差≤0.56 m,5%次的测试误差≤1.0 m,基本满足输电线路对于安全距离的测距要求。仿真和测试结果表明了所提方法的有效性,并指出需要进一步研究的方向。
[Abstract]:In order to determine more accurately the safe distance of live operation of transmission line, a field intensity vector location method is proposed. The calculation model of the field intensity in the space around the transmission line is established. According to the vector component of the field intensity at the measuring point and the maximum value of the composite field intensity and the measurement error of the field intensity sensor, the field intensity of the measuring position may be close to the coordinate set of the point. The coordinate set is divided into different point groups according to the mathematical clustering method. According to the moving characteristics of field intensity measurement points, an accurate tracking location can be realized by determining a real close to the center of a group of points. Finally, the simulation example of 220kV transmission line shows that the distance error of the measuring point of 82.7% field strength is 鈮，
