摘要:諧波主要是由稱為諧波源的大功率換流設(shè)備及其它非線性負(fù)荷產(chǎn)生。諧波源產(chǎn)生的諧波不但危及電網(wǎng)及其它電力用戶,而且也危及自身,因此,諧波的治理是十分必要且有實(shí)際經(jīng)濟(jì)效益的。本文以大明鋁合金型材有限公司為實(shí)例,對(duì)諧波的產(chǎn)生及治理方案進(jìn)行了分析研究。治理方案充分考慮了經(jīng)濟(jì)和技術(shù)方面因素,既獲得良好治理效果又節(jié)約了成本。

Abstract:Harmonic results from the so-called harmonic sources, like high-power inversion equipment and other non-linear load. Harmonic from harmonic sources endangers not only the grid and its users, but also itself,thus making the suppression a necessity and an economical action. The paper, taking Daming Aluminium Material Co., Ltd as an example, analyses the origin of harmonic and its suppression. The suppression scheme takes into consideration several matters, such as economical and technological factors, so as to make it efficient and cost-saving.
