摘要电子式电流互感器凭借绝缘简单、体积小、重量轻、动态范围宽、无磁饱和等优良特性在变电站中得到了广泛应用。随着变电站电压等级的不断提高,开关操作过电压,尤其是隔离开关特快速暂态过电压（VFTO）对变电站电子式互感器的电磁干扰问题得到了越来越多的关注。分析了高压变电站VFTO产生和传播的物理过程,建立了电子式电流互感器罗氏线圈的高频暂态模型,得到了VFTO作用下罗氏线圈端口的信号波形。通过对比集中参数、分布参数以及实测的信号波形,证明分布参数模型可更好地反映罗氏线圈在VFTO作用下的高频特性。

Abstract：Electronic current transformers, with excellent properties of simple insulation, small volume, light weight, wide dynamic range, and no magnetic saturation, have been widely used in substations. With the fast improvement of substation voltage grade, the electromagnetic interference (EMI) problem of switching operation overvoltage, especially very fast transient overvoltage (VFTO), on electronic transformers in substations has gotten more and more attention. In this paper, the physical process of VFTO in high voltage substations is analyzed. The high frequency model of Rogowski coil in electronic transformers under VFTO is built, the simulated waveform of the signals at the output ports of Rogowski coil is obtained. It is proved that the distribution parameters model can reflect the high frequency characteristics better by comparing the waveform of distribution parameter model, lumped parameter model and the measured signal waveform.

Key words： Electronic transformer Rogowski coil very fast transient overvoltage electromagnetic compatibility
