电力系统中线路电流的测量方法、装置、设备及存储介质
摘要：
本发明公开了一种电力系统中线路电流的测量方法，只需要获取待测导线在三个单轴磁传感器的磁敏感方向上产生的第一磁感应强度、第二磁感应强度、第三磁感应强度以及三个单轴磁传感器之间的相对距离，就可计算出待测导线的电流值，实现对待测导线电流的测量。同时，对于三个单轴磁传感器，只要保证三个单轴磁传感器位于同一直线，且该直线与待测导线不共面，三个单轴磁传感器的磁敏感方向同方向且平行于三个单轴磁传感器所在的直线即可。在安装时，无需固定一次回路导线与三个单轴磁传感器的相对位置，进而减小了安装难度，提高了测量准确性。另外，本发明还公开了一种电力系统中线路电流的测量装置、设备及存储介质，效果如上。
摘要（英）：

The invention discloses a line current measuring method in a power system. The current value of a lead to be measured can be calculated by only obtaining first, second and third magnetic induction intensity generated by three uniaxial magnetic sensors in the magnetic sensitive directions respectively and the relative distances among the three uniaxial magnetic sensors, and the current of the leadto be measured is measured. The three uniaxial magnetic sensors are positioned in the same straight line, the straight line and the lead to be measured are not coplanar, the magnetic sensitive directions of the three uniaxial magnetic sensors are in the same direction and are in parallel with the straight line where the three uniaxial magnetic sensors are positioned. During installation, it is notrequired to fix the relative positions of primary loop lead and the three uniaxial magnetic sensors, installation is less difficult, and the measuring accuracy is improved. The invention also discloses a line current measuring device and equipment in the power system and a storage medium with the above effects.
