摘　　要：宝钢低压动力配电系统中有许多变频水泵、风机等,这些变频装置在运行过程中产生的谐波和瞬流浪涌,可能导致系统中运行设备不明原因的停机、故障、耗电和使用寿命的缩短,还没有相应的抑制设备来对应。为了贯彻落实国家节能减排政策,我们立项研究了谐波在低压配电系统中造成的损耗和瞬流浪涌对系统的影响,并提出了解决方案。There are manyvariable frequency fans or Pumps which produce harmonics and surge in Baosteel power supply system. The harmonics and surge can induce producing equipments shutting-down, fault, high power consumption and short service life, and scarcely any equipment can solve all of these problems. For responding energy saving and pollution reduction policy in our country, the research is done on the influence of harmonics to the power supply system, and solution is brought forward in this paper.
