當(dang)電(dian)(dian)(dian)網(wang)(wang)的(de)負(fu)荷呈感(gan)性時，如(ru)電(dian)(dian)(dian)動機、電(dian)(dian)(dian)焊機等負(fu)載，這(zhe)時電(dian)(dian)(dian)網(wang)(wang)的(de)電(dian)(dian)(dian)流(liu)滯帶(dai)后電(dian)(dian)(dian)壓一(yi)個角度，當(dang)負(fu)荷呈容性時，如(ru)過(guo)量的(de)補(bu)償(chang)裝(zhuang)(zhuang)置的(de)控(kong)制器(qi)，這(zhe)是時電(dian)(dian)(dian)網(wang)(wang)的(de)電(dian)(dian)(dian)流(liu)超(chao)前于電(dian)(dian)(dian)壓的(de)一(yi)個角度，即功率(lv)因(yin)數超(chao)前或(huo)滯后是指電(dian)(dian)(dian)流(liu)與(yu)電(dian)(dian)(dian)壓的(de)相位關系。通(tong)過(guo)補(bu)償(chang)裝(zhuang)(zhuang)置的(de)控(kong)制器(qi)檢(jian)測(ce)供電(dian)(dian)(dian)系統的(de)物理量，來決定電(dian)(dian)(dian)容器(qi)的(de)投切量，這(zhe)個物理量可以是功率(lv)因(yin)數或(huo)無(wu)功電(dian)(dian)(dian)流(liu)或(huo)無(wu)功功率(lv)。

電力中無功補(bu)償元器(qi)件(jian)的補(bu)償標準是什么

變(bian)(bian)壓(ya)(ya)器諧波電(dian)流(liu)是(shi)由其(qi)勵(li)磁回路的(de)非線性引起(qi)的(de)，產生諧波電(dian)流(liu)的(de)大小與變(bian)(bian)壓(ya)(ya)器的(de)鐵(tie)心結構(gou)、鐵(tie)心飽和(he)程度以及(ji)變(bian)(bian)壓(ya)(ya)器的(de)連接力式都有關系(xi)。電(dian)力系(xi)統運行的(de)內、外(wai)故障也(ye)會造成(cheng)電(dian)能質(zhi)量(liang)問(wen)題，如短路故障、雷擊、誤操作、電(dian)網故障時發電(dian)機及(ji)勵(li)磁系(xi)統的(de)工作狀態的(de)改(gai)變(bian)(bian)、故障保護(hu)裝置(zhi)中的(de)電(dian)力電(dian)子設備的(de)啟動(dong)等都將造成(cheng)各(ge)種(zhong)電(dian)能質(zhi)量(liang)問(wen)題。

串聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)容(rong)器用于賠(pei)償輸(shu)配電(dian)(dian)(dian)線(xian)路的(de)(de)感抗，具有減少電(dian)(dian)(dian)氣設備間(jian)距提(ti)升可(ke)靠性水準(zhun)和線(xian)路的(de)(de)輸(shu)配電(dian)(dian)(dian)容(rong)積的(de)(de)功效。串聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)容(rong)器組多見串、串聯(lian)(lian)(lian)(lian)組成，串聯(lian)(lian)(lian)(lian)紗支由線(xian)路運輸(shu)容(rong)積而(er)定，串聯(lian)(lian)(lian)(lian)數量則由需要的(de)(de)串聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)容(rong)器賠(pei)償度（串聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)容(rong)器的(de)(de)容(rong)抗與(yu)所(suo)賠(pei)償的(de)(de)線(xian)路感抗之(zhi)比）而(er)定。小試控投串聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)容(rong)器賠(pei)償一(yi)般(ban)在(zai)50下(xia)列，不適合過高(gao)，以防造成系統軟件的(de)(de)次同步諧振。輸(shu)電(dian)(dian)(dian)網因其特性阻(zu)抗不勻(yun)而(er)導致電(dian)(dian)(dian)場(chang)時，也能用串聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)容(rong)器來賠(pei)償。日本國在(zai)110kV雙回路中應用了串聯(lian)(lian)(lian)(lian)電(dian)(dian)(dian)容(rong)器賠(pei)償。
