無(wu)功補償的(de)(de)基本原理：電(dian)(dian)(dian)(dian)(dian)網(wang)輸出(chu)的(de)(de)功率(lv)(lv)包(bao)括兩部分(fen)(fen)：一是(shi)有(you)功功率(lv)(lv)：直接消耗(hao)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)，把電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)轉(zhuan)變為機(ji)械(xie)能(neng)(neng)(neng)、熱能(neng)(neng)(neng)、化學能(neng)(neng)(neng)或聲能(neng)(neng)(neng)，利用這些能(neng)(neng)(neng)作功，這部分(fen)(fen)功率(lv)(lv)稱為有(you)功功率(lv)(lv)；二(er)是(shi)無(wu)功功率(lv)(lv)：不消耗(hao)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)，只是(shi)把電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)轉(zhuan)換(huan)為另(ling)一種(zhong)形式的(de)(de)能(neng)(neng)(neng)，這種(zhong)能(neng)(neng)(neng)作為電(dian)(dian)(dian)(dian)(dian)氣設備能(neng)(neng)(neng)夠作功的(de)(de)必(bi)備條件(jian)(jian)，并且(qie)，這種(zhong)能(neng)(neng)(neng)是(shi)在(zai)電(dian)(dian)(dian)(dian)(dian)網(wang)中與電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)進(jin)行周期性轉(zhuan)換(huan)，這部分(fen)(fen)功率(lv)(lv)稱為無(wu)功功率(lv)(lv)（如電(dian)(dian)(dian)(dian)(dian)磁元件(jian)(jian)建(jian)立磁場占(zhan)用的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)，電(dian)(dian)(dian)(dian)(dian)容器(qi)建(jian)立電(dian)(dian)(dian)(dian)(dian)場所占(zhan)的(de)(de)電(dian)(dian)(dian)(dian)(dian)能(neng)(neng)(neng)）。

智能建筑中低壓補償模組(zu)的(de)諧波放大問題解決辦法(fa)

電網的(de)(de)損(sun)(sun)耗分(fen)(fen)為管理(li)線(xian)(xian)損(sun)(sun)和(he)技(ji)術線(xian)(xian)損(sun)(sun)。管理(li)線(xian)(xian)損(sun)(sun)通過管理(li)和(he)組織上的(de)(de)措施(shi)來降(jiang)(jiang)低；技(ji)術線(xian)(xian)損(sun)(sun)通過各種技(ji)術措施(shi)來降(jiang)(jiang)低。無(wu)功補償(chang)是利(li)用技(ji)術措施(shi)降(jiang)(jiang)低線(xian)(xian)損(sun)(sun)的(de)(de)重要措施(shi)之一，在有功功率(lv)合理(li)分(fen)(fen)配的(de)(de)同時，做(zuo)到無(wu)功功率(lv)的(de)(de)合理(li)分(fen)(fen)布(bu)。按照就近(jin)的(de)(de)原(yuan)則安(an)排減少無(wu)功遠(yuan)距離輸送(song)。對各種方(fang)式進(jin)行線(xian)(xian)損(sun)(sun)計算(suan)制定合理(li)的(de)(de)運行方(fang)式；合理(li)調整和(he)利(li)用補償(chang)設(she)備提高功率(lv)因數。

現在用電(dian)設(she)備有(you)很(hen)多，如電(dian)子、中頻、變頻等(deng)設(she)備，會產(chan)生諧(xie)(xie)波。有(you)了諧(xie)(xie)波，電(dian)流(liu)、電(dian)壓(ya)、波形發生畸變，損(sun)壞電(dian)力電(dian)容器、接觸器、熔斷(duan)器，嚴重時(shi)會引起火災，燒毀(hui)用電(dian)設(she)備。解(jie)決方法：1、諧(xie)(xie)波不嚴重的(de)(de)提高電(dian)容器電(dian)壓(ya)等(deng)級。2、諧(xie)(xie)波嚴重的(de)(de)要配置抗諧(xie)(xie)波的(de)(de)電(dian)抗器，但(dan)這(zhe)種電(dian)抗器的(de)(de)造(zao)價相(xiang)對(dui)比(bi)較高。
