無(wu)功(gong)(gong)補(bu)償的基本原理：電(dian)網輸(shu)出的功(gong)(gong)率(lv)(lv)(lv)(lv)包(bao)括兩部分;一(yi)是(shi)有功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv);二(er)是(shi)無(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv).直(zhi)接消耗電(dian)能(neng),把電(dian)能(neng)轉(zhuan)(zhuan)變為(wei)機械能(neng),熱能(neng),化學(xue)能(neng)或聲能(neng),利用這些能(neng)作(zuo)(zuo)(zuo)功(gong)(gong),這部分功(gong)(gong)率(lv)(lv)(lv)(lv)稱為(wei)有功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv);不消耗電(dian)能(neng);只是(shi)把電(dian)能(neng)轉(zhuan)(zhuan)換為(wei)另一(yi)種(zhong)(zhong)形式的能(neng),這種(zhong)(zhong)能(neng)作(zuo)(zuo)(zuo)為(wei)電(dian)氣(qi)設(she)備能(neng)夠作(zuo)(zuo)(zuo)功(gong)(gong)的必備條件,并且(qie),這種(zhong)(zhong)能(neng)是(shi)在(zai)電(dian)網中與電(dian)能(neng)進行周期性轉(zhuan)(zhuan)換,這部分功(gong)(gong)率(lv)(lv)(lv)(lv)稱為(wei)無(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv)。

首次裝置無功(gong)補償(chang)模組在(zai)光伏(fu)產(chan)業中的作用

電(dian)容器的過電(dian)流(liu)(liu)危害。① 電(dian)容器組投入(ru)瞬間由于電(dian)容端電(dian)壓不(bu)能躍變(bian)，會產生合(he)(he)閘(zha)涌流(liu)(liu)，一般合(he)(he)閘(zha)涌流(liu)(liu)為正常電(dian)流(liu)(liu)幅值的6～8倍。對斷(duan)路器的滅(mie)弧室產生很大機(ji)械應力，使滅(mie)弧室受到(dao)破(po)壞，為防(fang)止合(he)(he)閘(zha)涌流(liu)(liu)造成的損壞，應盡量減少投切次數，或在電(dian)容器組中串入(ru)小電(dian)抗(kang)器。

在遠(yuan)距離輸電(dian)線(xian)(xian)路(lu)正中(zhong)(zhong)間(jian)(jian)安(an)置同歩(bu)調相(xiang)機或靜止(zhi)不(bu)動賠償(chang)設備，運(yun)(yun)用這種設備的無(wu)功(gong)功(gong)率(lv)調整工作能力，在線(xian)(xian)路(lu)負載(zai)時消化(hua)吸收(shou)線(xian)(xian)路(lu)電(dian)池充電(dian)輸出功(gong)率(lv)，限定電(dian)壓(ya)上升；在線(xian)(xian)路(lu)輕載(zai)時傳出無(wu)功(gong)負荷，以賠償(chang)線(xian)(xian)路(lu)的無(wu)功(gong)功(gong)率(lv)耗損，適用電(dian)壓(ya)水(shui)準，進而(er)提(ti)升線(xian)(xian)路(lu)的運(yun)(yun)輸容積。正中(zhong)(zhong)間(jian)(jian)同歩(bu)或靜止(zhi)不(bu)動賠償(chang)一(yi)般建(jian)在線(xian)(xian)路(lu)圓(yuan)心，若建(jian)在線(xian)(xian)路(lu)首尾端，則緩沖作用消退。
