隨著電(dian)(dian)(dian)(dian)(dian)力系(xi)(xi)統(tong)(tong)規模的(de)(de)不(bu)斷擴大(da)以(yi)及系(xi)(xi)統(tong)(tong)中(zhong)非線性負荷的(de)(de)不(bu)斷增加，電(dian)(dian)(dian)(dian)(dian)力系(xi)(xi)統(tong)(tong)受(shou)到的(de)(de)諧波(bo)污染也越來越嚴重，加上電(dian)(dian)(dian)(dian)(dian)力系(xi)(xi)統(tong)(tong)可能(neng)出現的(de)(de)內外(wai)故障，這大(da)大(da)惡化了系(xi)(xi)統(tong)(tong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)質(zhi)量(liang)。在(zai)電(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)子裝置大(da)量(liang)使(shi)用以(yi)前，電(dian)(dian)(dian)(dian)(dian)力系(xi)(xi)統(tong)(tong)中(zhong)主要的(de)(de)諧波(bo)源是(shi)(shi)發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)和電(dian)(dian)(dian)(dian)(dian)力變壓器。發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)是(shi)(shi)公用電(dian)(dian)(dian)(dian)(dian)網的(de)(de)電(dian)(dian)(dian)(dian)(dian)源。在(zai)實際運行中(zhong)，由于多(duo)種原因，發(fa)電(dian)(dian)(dian)(dian)(dian)機(ji)的(de)(de)感應電(dian)(dian)(dian)(dian)(dian)動勢不(bu)是(shi)(shi)理想的(de)(de)正(zheng)弦(xian)波(bo)，因此(ci)其輸出電(dian)(dian)(dian)(dian)(dian)壓中(zhong)也包含一定的(de)(de)諧波(bo)。

電(dian)力(li)系統無功補償(chang)如何解(jie)決諧波對電(dian)氣設備所造成的影響

產(chan)品為整體(ti)性(xing)設(she)備(bei)，以遠景需要配(pei)(pei)置，一(yi)次性(xing)投資，產(chan)品一(yi)旦(dan)形成后，其配(pei)(pei)置和無(wu)(wu)功補(bu)償的調(diao)整十分困難。產(chan)品為組合式組件設(she)備(bei)，可當前(qian)需要和經濟(ji)能(neng)力配(pei)(pei)置，日(ri)后方(fang)可按情況擴展(zhan)，實現分期投資，在(zai)使用(yong)現場可以方(fang)便(bian)地(di)進行容(rong)量配(pei)(pei)置調(diao)整，實現無(wu)(wu)功補(bu)償優化，日(ri)后改造(zao)和增(zeng)容(rong)方(fang)便(bian)，通(tong)俗簡便(bian)。

所(suo)謂無功補償技術(shu)，即采(cai)用(yong)降(jiang)低運行中的(de)(de)電(dian)(dian)力(li)(li)(li)網損耗，提(ti)升電(dian)(dian)力(li)(li)(li)資源利用(yong)率的(de)(de)一(yi)種(zhong)技術(shu)。換言之(zhi)，它是(shi)一(yi)種(zhong)通過提(ti)高供(gong)電(dian)(dian)設備的(de)(de)增容，來實現(xian)控(kong)制(zhi)供(gong)電(dian)(dian)系(xi)統(tong)和配電(dian)(dian)系(xi)統(tong)的(de)(de)電(dian)(dian)壓，進而有(you)效提(ti)升了企業對電(dian)(dian)力(li)(li)(li)設備和系(xi)統(tong)的(de)(de)控(kong)制(zhi)力(li)(li)(li)的(de)(de)一(yi)種(zhong)技術(shu)。
