摘要
供电网络中电力器件及其装置的使用和非线性负荷在电网中的投运 ,伴生了大量的高次谐波 ,引起电网正弦波形严重畸变。这将干扰通讯设备运行 ,影响计量仪表精度 ,甚至造成电气设备烧毁。本文分析了配电网络高谐产生的因素 ,指出了它的主要危害 。
High harmonic wave is largely associated with power use of electronic apparatus and the operation of non-linear load in power network. It caused severe sine wave aberrance. In this case, it will disturb equipment operation and influence instrument measuring accuracy and even result in electric equipment damage. This article analyzed the occurred factors of High harmonic wave in power distribution network, pointed out its main harm and proposed the preventive measures in this regard.
