摘要 空间电场信息的准确感知在电力系统传感和量测技术中具有重要价值,但目前并没有可靠的空间直流电场测量装置,对空间三维电场传感器的标定方法需要进一步研究。该文在三维可调外界电场下构建了同时含有维间耦合和角度偏差的校准模型,提出了在该模型下基于差分进化算法求解灵敏度系数矩阵的方法。通过对比研究发现该方法较为精确、稳定和快速,在多组仿真实验中误差率均小于3%(不考虑测量误差)。此外,对传感器空间角度对算法准确度的影响进行了分析。基于差分进化算法的三维电场传感器解耦标定方法,既可以简化标定装置设计的复杂度和难度,也可为其他类型的三维传感器标定提供参考。

Abstract:The information sensing of space electric field has important value in the sensing and measurement technology of power system. However, at present, there is no reliable measurement device of space DC electric field. The calibration method of space three-dimensional electric field sensor needs to be further studied. In this paper, a calibration model with inter-dimensional coupling and angular deviation is established under a three-dimensional adjustable external electric field. A method of solving the sensitivity coefficient matrix based on the differential evolution algorithm under this model is proposed. This method is more accurate and stable through the comparative study, and the error rate is less than 3% in multiple sets of simulation experiments (measurement error is not included). In addition, the variation of accuracy with the range of angle values is discussed, which can further improve the accuracy of the algorithm and the accuracy of calibration. The three-dimensional electric field sensor decoupling calibration method based on differential evolution algorithm can simplify the complexity and difficulty of calibration device design, and can also provide reference for other types of three-dimensional sensor calibration.
