汽車焊接車間濾波補償模組在(zai)光伏產業(ye)中的作用

變(bian)壓器諧波(bo)電流是由其勵磁(ci)(ci)回路的(de)(de)非線性引起的(de)(de)，產生(sheng)諧波(bo)電流的(de)(de)大小與變(bian)壓器的(de)(de)鐵心(xin)結構、鐵心(xin)飽和程度以及(ji)(ji)變(bian)壓器的(de)(de)連接(jie)力式都有關(guan)系。電力系統(tong)運行的(de)(de)內、外(wai)故障也(ye)會(hui)造(zao)成電能(neng)質(zhi)(zhi)量問題，如短路故障、雷擊、誤操(cao)作、電網故障時發電機及(ji)(ji)勵磁(ci)(ci)系統(tong)的(de)(de)工作狀態的(de)(de)改(gai)變(bian)、故障保護裝置(zhi)中的(de)(de)電力電子設(she)備的(de)(de)啟動(dong)等都將(jiang)造(zao)成各種電能(neng)質(zhi)(zhi)量問題。

串(chuan)(chuan)聯(lian)電(dian)(dian)(dian)容(rong)器(qi)用于賠(pei)(pei)償(chang)(chang)輸(shu)配電(dian)(dian)(dian)線(xian)路的感抗，具(ju)有減(jian)少電(dian)(dian)(dian)氣設備(bei)間(jian)距提升可靠(kao)性水(shui)準(zhun)和(he)線(xian)路的輸(shu)配電(dian)(dian)(dian)容(rong)積的功效。串(chuan)(chuan)聯(lian)電(dian)(dian)(dian)容(rong)器(qi)組多(duo)見串(chuan)(chuan)、串(chuan)(chuan)聯(lian)組成，串(chuan)(chuan)聯(lian)紗支(zhi)由(you)線(xian)路運輸(shu)容(rong)積而定(ding)，串(chuan)(chuan)聯(lian)數量則由(you)需要的串(chuan)(chuan)聯(lian)電(dian)(dian)(dian)容(rong)器(qi)賠(pei)(pei)償(chang)(chang)度(du)（串(chuan)(chuan)聯(lian)電(dian)(dian)(dian)容(rong)器(qi)的容(rong)抗與所賠(pei)(pei)償(chang)(chang)的線(xian)路感抗之比）而定(ding)。小試控投串(chuan)(chuan)聯(lian)電(dian)(dian)(dian)容(rong)器(qi)賠(pei)(pei)償(chang)(chang)一般在(zai)50下列，不適合(he)過高，以防造成系(xi)統(tong)軟件的次同步諧振。輸(shu)電(dian)(dian)(dian)網因其(qi)特性阻抗不勻而導致電(dian)(dian)(dian)場時(shi)，也能用串(chuan)(chuan)聯(lian)電(dian)(dian)(dian)容(rong)器(qi)來賠(pei)(pei)償(chang)(chang)。日本國在(zai)110kV雙回路中應用了串(chuan)(chuan)聯(lian)電(dian)(dian)(dian)容(rong)器(qi)賠(pei)(pei)償(chang)(chang)。
