为了方便简单地测量消弧线圈接地系统中线路的对地参数，提出了一种基于零序电压幅值增量的消弧线圈调谐新方法。该方法在配电网中性点增加了消弧线圈及电阻，并入电阻之前，先测量出系统中零序电压幅值；并入电阻之后，再次测量系统中零序电压幅值，然后改变消弧线圈电感值，进一步测量系统中零序电压幅值，并对几次测量值进行记录。依据所记录的测量值，代入公式即可精确地求出线路对地总电容与总电阻。最后，利用Matlab搭建模型进行实验仿真，该方法不需要测量零序电压的相位，具有操作简单、精度较高等优点，对消弧线圈调谐有重要意义。

In order to conveniently and simply measure the line-to-ground parameters in arc suppression coil grounding system, a new tuning method of arc suppression coil based on the increment of zero-sequence voltage amplitudes is proposed.In this method,the distribution network neutral point will be added the arc suppression coil and resistor , firstly measure the amplitude of the zero sequence voltage before incorporated resistance ;and measure the amplitude of the zero sequence voltage again after incorporated resistance , and then adjust the arc suppression coil inductance val-ue, further measure and record the amplitude of the zero sequence voltage .According to the recorded measured val-ues, it can be substituted into the equation to obtain the total capacitance and resistance to line -to-ground.Finally, build a model using Matlab simulation experiment and this method needn ’ t measure zero-sequence voltage phase .It has the advantages of simple operation , high accuracy and so on .It is very significant for the tuning of the arc sup-pression coil .
