電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)(qi)在(zai)(zai)原(yuan)理上(shang)相當于(yu)產生(sheng)容(rong)(rong)(rong)(rong)性(xing)無功(gong)(gong)電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)(de)發(fa)電(dian)(dian)(dian)(dian)(dian)機。其無功(gong)(gong)補(bu)償的(de)(de)(de)(de)(de)(de)原(yuan)理是把具(ju)有容(rong)(rong)(rong)(rong)性(xing)功(gong)(gong)率負(fu)荷(he)的(de)(de)(de)(de)(de)(de)裝置和(he)感性(xing)功(gong)(gong)率負(fu)荷(he)并聯(lian)在(zai)(zai)同(tong)一(yi)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)(qi)上(shang)，能(neng)量在(zai)(zai)兩種(zhong)負(fu)荷(he)間相互(hu)轉換。這樣，電(dian)(dian)(dian)(dian)(dian)網中的(de)(de)(de)(de)(de)(de)變壓器(qi)(qi)(qi)和(he)輸(shu)(shu)電(dian)(dian)(dian)(dian)(dian)線路(lu)的(de)(de)(de)(de)(de)(de)負(fu)荷(he)降低，從而輸(shu)(shu)出有功(gong)(gong)能(neng)力(li)增加。在(zai)(zai)輸(shu)(shu)出一(yi)定有功(gong)(gong)功(gong)(gong)率的(de)(de)(de)(de)(de)(de)情況下，供電(dian)(dian)(dian)(dian)(dian)系統的(de)(de)(de)(de)(de)(de)損耗(hao)降低。比較起來電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)(qi)是減輕變壓器(qi)(qi)(qi)、供電(dian)(dian)(dian)(dian)(dian)系統和(he)工(gong)業配電(dian)(dian)(dian)(dian)(dian)負(fu)荷(he)的(de)(de)(de)(de)(de)(de)簡便、經濟的(de)(de)(de)(de)(de)(de)方法。因此，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)(qi)作(zuo)為電(dian)(dian)(dian)(dian)(dian)力(li)系統的(de)(de)(de)(de)(de)(de)無功(gong)(gong)補(bu)償勢在(zai)(zai)必行。當前(qian)，采用(yong)并聯(lian)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)器(qi)(qi)(qi)作(zuo)為無功(gong)(gong)補(bu)償裝置已(yi)經非常普遍。
