摘要

现代办公设备等非线性负载的激增会引起电源中的谐波。在电源中出现的谐波将倾向于流过中性电流,即使是在电源中三相平衡的基本电流。在中性点导体的尺寸方面,应适当注意这些中性点电流。本文讨论了谐波的相关问题和中性施胶的关注。

Power quality issues in a distribution network impact of neutral current due to nonlinear loads
Proliferation of nonlinear loads like modern office equipment cause harmonics in the supply. Harmonics appearing in the supply will tend to flow the neutral current even for three phase balanced fundamental currents in the source. Proper attention for these neutral currents is to be given in the aspect of neutral conductor sizing. This paper addresses the related issues of the harmonics and concern of neutral sizing.
