为了改善消弧线圈补偿的补偿效果，提出了一种基于恒定零序电压幅值的消弧线圈调谐新法。该方法通过在配电网中性点增加消弧线圈及电阻，更换电阻之后，调节消弧线圈电感值，同时观察和测量中性点偏移电压有效值的大小，来配合消弧线圈的进一步调节。当改变电阻前后中性点偏移电压有效值相同时，联立方程，可以精确地求出配电网对地电容总和与对地电阻总和gΣ，从而确定消弧线圈全补偿时的电感值L0。通过Matlab仿真和理论计算，验证了该方法能够取得比较精确的补偿效果。该方法具有操作简单，测量精度高，补偿效果好等优点，可以应用于消弧线圈调谐领域。CΣ

In order to improve the compensation effect of the arc suppression coil, a new tuning method of arc suppression coil based on the constant zero-sequence voltage amplitude is proposed. In this method, the arc suppression coil and resistor are added in the distribution network neutral point. After replacing the resistor, it adjusts the arc suppression coil inductance value, while observes and measures the size of the neutral point offset voltage rms, to coordinate the further adjustment of the arc suppression coil. When the neutral point offset voltage rms is identical before and after replacing the resistor, simultaneous equations, the sum of the capacitance to ground CΣand the sum of the resistance to ground gΣ in the distribution network can be accurately obtained, thus to determine the value of arc suppression coil fully compensated inductor L 0 . Matlab simulation and theoretical calculation verify that the method can obtain a more precise compensation effect. This method has the advantages of simple operation, high accuracy, good compensation effect, so it can be applied to the areas of arc suppression coil tuning.
