項目背景：

在(zai)(zai)某大型(xing)商業綜合體配(pei)(pei)電(dian)(dian)(dian)室四臺變(bian)(bian)壓(ya)器以(yi)及(ji)配(pei)(pei)電(dian)(dian)(dian)線路上(shang)存在(zai)(zai)大量(liang)(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)，電(dian)(dian)(dian)流(liu)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)加(jia)劇了電(dian)(dian)(dian)壓(ya)畸變(bian)(bian)，導致各(ge)(ge)變(bian)(bian)壓(ya)器下(xia)(xia)使用(yong)(yong)的(de)(de)(de)(de)電(dian)(dian)(dian)容柜均出現不同程(cheng)(cheng)度的(de)(de)(de)(de)損壞、由于用(yong)(yong)電(dian)(dian)(dian)負載主要為單相負載，產生了大量(liang)(liang)的(de)(de)(de)(de)3次(ci)(ci)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)，3次(ci)(ci)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)在(zai)(zai)中線上(shang)疊加(jia)、配(pei)(pei)電(dian)(dian)(dian)室出現過N線燒毀的(de)(de)(de)(de)情況，經測(ce)量(liang)(liang)N線最(zui)大諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)達到500-600A，經過詳細(xi)分(fen)析，測(ce)量(liang)(liang)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)含量(liang)(liang)，最(zui)終確定四臺變(bian)(bian)壓(ya)器下(xia)(xia)各(ge)(ge)安(an)裝一臺200A有(you)(you)源電(dian)(dian)(dian)力濾波(bo)(bo)(bo)器的(de)(de)(de)(de)方案，主要對系統中含有(you)(you)的(de)(de)(de)(de)3次(ci)(ci)及(ji)以(yi)上(shang)各(ge)(ge)次(ci)(ci)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)進行治(zhi)理(li)。電(dian)(dian)(dian)流(liu)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)治(zhi)理(li)后，3次(ci)(ci)及(ji)以(yi)上(shang)電(dian)(dian)(dian)流(liu)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)也(ye)在(zai)(zai)國標(biao)允許(xu)值之內，電(dian)(dian)(dian)壓(ya)諧(xie)(xie)(xie)(xie)(xie)波(bo)(bo)(bo)得到很大程(cheng)(cheng)度的(de)(de)(de)(de)降低，有(you)(you)效的(de)(de)(de)(de)保(bao)護變(bian)(bian)壓(ya)器、配(pei)(pei)電(dian)(dian)(dian)柜、以(yi)及(ji)設(she)備(bei)的(de)(de)(de)(de)使用(yong)(yong)安(an)全，延長設(she)備(bei)的(de)(de)(de)(de)壽命。

治理方案：

根據實際工況和測(ce)量(liang)結果發現，諧(xie)波(bo)(bo)主(zhu)要由(you)LED燈、空調機組、冷柜、電(dian)(dian)梯(ti)等負載產(chan)生，按照成熟完善的(de)整套諧(xie)波(bo)(bo)治(zhi)理解決方(fang)案，奧順電(dian)(dian)氣有(you)些(xie)公司提出使用并聯型有(you)源電(dian)(dian)力濾(lv)波(bo)(bo)器，自(zi)動跟蹤治(zhi)理負載產(chan)生的(de)諧(xie)波(bo)(bo)電(dian)(dian)流，保證整個系統安全可靠運行，采用APF集中治(zhi)理方(fang)式解決諧(xie)波(bo)(bo)干擾問(wen)題(ti)。

治理效果：

使用有源濾波(bo)設備后(hou)，諧波(bo)畸變(bian)問(wen)題基本解決，諧波(bo)治理方(fang)案得到客(ke)戶認可！
