某汽(qi)車(che)基(ji)地焊裝(zhuang)車(che)間因(yin)現場機(ji)器(qi)人(ren)電(dian)(dian)(dian)(dian)焊機(ji)、密集(ji)頻繁起(qi)停工作，導(dao)致(zhi)現場電(dian)(dian)(dian)(dian)能質(zhi)量污染(ran)嚴重，不僅(jin)供(gong)(gong)電(dian)(dian)(dian)(dian)系(xi)統(tong)存在諧波含量超標，對變壓(ya)器(qi)，電(dian)(dian)(dian)(dian)纜，電(dian)(dian)(dian)(dian)機(ji)，供(gong)(gong)電(dian)(dian)(dian)(dian)母線等有(you)功功率損耗增大(da)；而且設備(bei)負(fu)荷(he)特(te)性(xing)致(zhi)使三相電(dian)(dian)(dian)(dian)流不平(ping)衡且反復(fu)沖(chong)擊電(dian)(dian)(dian)(dian)流大(da)，因(yin)此，無功功率因(yin)數平(ping)均值(zhi)為0.75，這樣使得生(sheng)產供(gong)(gong)電(dian)(dian)(dian)(dian)系(xi)統(tong)電(dian)(dian)(dian)(dian)壓(ya)不穩定，產品焊接質(zhi)量得不到保(bao)障，影響(xiang)成(cheng)品合格率。
為此(ci)，該車(che)間電能質(zhi)量(liang)急需提升，確(que)保(bao)無功功率(lv)因數符(fu)合生產需求(qiu)，杜(du)絕安全(quan)隱患并保(bao)障安全(quan)穩定(ding)生產，同時符(fu)合節能減(jian)排需求(qiu)。
方法二、采用(yong)有(you)源(yuan)電(dian)力(li)(li)濾波(bo)(bo)(bo)(bo)器進(jin)行諧(xie)波(bo)(bo)(bo)(bo)治(zhi)理，有(you)源(yuan)電(dian)力(li)(li)濾波(bo)(bo)(bo)(bo)器（APF）是一種用(yong)于動(dong)態抑制(zhi)(zhi)諧(xie)波(bo)(bo)(bo)(bo)、補(bu)償無功的(de)新型電(dian)力(li)(li)電(dian)子裝置，它(ta)能(neng)(neng)夠對不同大(da)小(xiao)和(he)頻率的(de)諧(xie)波(bo)(bo)(bo)(bo)進(jin)行快(kuai)(kuai)速(su)跟蹤(zong)補(bu)償。它(ta)可以通過采樣負載電(dian)流并(bing)進(jin)行各次諧(xie)波(bo)(bo)(bo)(bo)和(he)無功的(de)分離，控制(zhi)(zhi)并(bing)主動(dong)輸出電(dian)流的(de)大(da)小(xiao)、頻率和(he)相位，并(bing)且快(kuai)(kuai)速(su)響(xiang)應，抵消負載中相應電(dian)流，實現了動(dong)態跟蹤(zong)補(bu)償，既補(bu)諧(xie)波(bo)(bo)(bo)(bo)又補(bu)無功和(he)不平衡(heng)的(de)功能(neng)(neng)。
