该方法不受零序电流大小、线路补偿情况、谐波强弱等影响，具有较高的理论和实用价值。
The method is independent of zero-sequence current's value, inductance compensation situation and harmonics components, so it is effective and robust.
在非线性电阻消谐方式下，正温度系数(PTC)热敏电阻和三次谐波滤波器可以较好地解决零序电压偏高的问题。
Positive temperature coefficient (PTC) thermistor and triple frequency harmonic filter can reduce zero sequence voltage when a nonlinear resistance is used to prevent ferroresonance.
尤其是第三个谐波，这将导致零序电流急剧增加，从而增加了中性线的电流。
This is particularly the case for the third harmonic, which causes a sharp increase in the zero sequence current, and therefore increases the current in the neutral conductor.
实验结果表明，该装置可对三相四线制系统中的谐波、负序、零序等电流分量进行补偿。
Experimental results prove the proposed control method can compensate the harmonic, negative sequence and zero sequence current components in the three phase four wire.
