光纖補償模(mo)組經(jing)濟效益(yi)分析(xi)

供電(dian)(dian)部門的(de)無功補(bu)(bu)償(chang)(chang)與用(yong)戶(hu)補(bu)(bu)償(chang)(chang)相結合，因為無功消耗大(da)約60%在配電(dian)(dian)變壓器(qi)中，其余的(de)消耗在用(yong)戶(hu)的(de)用(yong)電(dian)(dian)設備中，若兩者不能很好(hao)地配合，可能造成輕載或空載時過(guo)補(bu)(bu)償(chang)(chang)，滿負(fu)荷(he)時欠(qian)補(bu)(bu)償(chang)(chang)，使(shi)補(bu)(bu)償(chang)(chang)失去了它的(de)實(shi)際(ji)意義，得不到理想(xiang)的(de)效果(guo)。

在遠距離輸電線路(lu)(lu)正(zheng)中間(jian)安置同歩調(diao)相機或(huo)靜止(zhi)不(bu)動(dong)賠(pei)償設備，運用(yong)這種(zhong)設備的(de)無(wu)功(gong)功(gong)率(lv)調(diao)整工作(zuo)能力，在線路(lu)(lu)負(fu)(fu)載時消(xiao)化吸收線路(lu)(lu)電池充電輸出(chu)功(gong)率(lv)，限定電壓上升(sheng)；在線路(lu)(lu)輕載時傳出(chu)無(wu)功(gong)負(fu)(fu)荷，以賠(pei)償線路(lu)(lu)的(de)無(wu)功(gong)功(gong)率(lv)耗(hao)損，適用(yong)電壓水(shui)準，進(jin)而提升(sheng)線路(lu)(lu)的(de)運輸容積。正(zheng)中間(jian)同歩或(huo)靜止(zhi)不(bu)動(dong)賠(pei)償一般建在線路(lu)(lu)圓心，若建在線路(lu)(lu)首尾(wei)端，則緩沖(chong)作(zuo)用(yong)消(xiao)退(tui)。
