摘要:鋼鐵行業(yè)軋機(jī)系統(tǒng)無功量變化大,功率因數(shù)變化快,同時諧波含量大,主要以5 次、7 次為主,低壓側(cè)無源設(shè)備(FC 及SVC) 補(bǔ)償效果差,而SVG(靜止無功發(fā)生器)作為有源型補(bǔ)償裝置,可以完全替代傳統(tǒng)的無源補(bǔ)償設(shè)備,不僅能提高功率因數(shù),而且能濾除諧波,可以達(dá)到很好的效果。
敘詞:軋機(jī),諧波及無功,SVG(靜止無功發(fā)生器)
Abstract:In steel industry, the rolling mill system suffers rapid change in reactive power and power factors, and meanwhile, it containssignificant harmonic, mainly with 5 times or 7 times. Passive facilities (i.e. FC and SVC) over the low voltage side have a poorcompensation effect. As an active compensation tool, SVG(Static Var Generator) can fully replace the traditional passive compensationfacilities and achieve a better function, which can not only improve power factor, but also filter harmonic.
