功(gong)率(lv)(lv)補(bu)償裝置在(zai)電(dian)(dian)(dian)(dian)子供電(dian)(dian)(dian)(dian)系統中所(suo)承擔的(de)作用是(shi)提(ti)(ti)高電(dian)(dian)(dian)(dian)網的(de)功(gong)率(lv)(lv)因數，降低供電(dian)(dian)(dian)(dian)變壓(ya)器及輸送線路(lu)的(de)損(sun)耗(hao)，提(ti)(ti)高供電(dian)(dian)(dian)(dian)效(xiao)率(lv)(lv)，改善(shan)供電(dian)(dian)(dian)(dian)環境。所(suo)以無(wu)功(gong)功(gong)率(lv)(lv)補(bu)償裝置在(zai)電(dian)(dian)(dian)(dian)力供電(dian)(dian)(dian)(dian)系統中處在(zai)一個不可缺少(shao)的(de)非常重要的(de)位置。合(he)理的(de)選擇補(bu)償裝置，可以做(zuo)到 大限度的(de)減少(shao)網絡的(de)損(sun)耗(hao)，使(shi)電(dian)(dian)(dian)(dian)網質量提(ti)(ti)高。

諧(xie)(xie)波嚴重場合無功補償如何有效治(zhi)理諧(xie)(xie)波問(wen)題

(1)提(ti)高(gao)電網(wang)(wang)及負載的(de)功(gong)(gong)率因數(shu)，設備設計容(rong)量(liang)將(jiang)降低(di)，投資(zi)也從(cong)而(er)減(jian)(jian)少(shao)(shao)。(2)穩(wen)定電網(wang)(wang)電壓，提(ti)高(gao)電網(wang)(wang)質量(liang)。特別在長距離輸電線(xian)路(lu)中安(an)裝合適的(de)無功(gong)(gong)補償(chang)裝置可提(ti)高(gao)系統的(de)輸電能力及穩(wen)定性。(3)減(jian)(jian)少(shao)(shao)負荷電流，降低(di)線(xian)路(lu)電能損耗。(4)無功(gong)(gong)補償(chang)挖掘發供(gong)電設備潛(qian)力。在設備容(rong)量(liang)不變的(de)條件下，提(ti)高(gao)功(gong)(gong)率因數(shu)可以少(shao)(shao)送無功(gong)(gong)功(gong)(gong)率，便可以多送有功(gong)(gong)功(gong)(gong)率。(5)在三(san)相(xiang)負載不平衡的(de)場合，可對三(san)相(xiang)視在功(gong)(gong)率起到平衡作用(yong)。(6)無功(gong)(gong)補償(chang)可以減(jian)(jian)少(shao)(shao)用(yong)戶電費支出，避(bi)免因功(gong)(gong)率因數(shu)低(di)于規(gui)定值而(er)受罰，同(tong)時減(jian)(jian)少(shao)(shao)用(yong)戶內部因傳輸和分配無功(gong)(gong)功(gong)(gong)率造成的(de)有功(gong)(gong)功(gong)(gong)率損耗。

提(ti)(ti)升機(ji)作為大功率、頻繁啟動、周期性沖擊負荷以及采用硅整流裝置(zhi)對電網(wang)造成(cheng)的無功沖擊和(he)高次(ci)諧波(bo)污染等危害不僅危及電網(wang)安(an)全，同時(shi)也造成(cheng)提(ti)(ti)升機(ji)過電流、欠(qian)電壓等緊停故(gu)障的發生，影(ying)響了礦井(jing)生產。因此對提(ti)(ti)升機(ji)供電系統(tong)進行無功動態補償和(he)高次(ci)諧波(bo)治理，對于提(ti)(ti)高礦井(jing)提(ti)(ti)升機(ji)和(he)電網(wang)的安(an)全運行可靠性、提(ti)(ti)高企業的經濟效益意義巨大。
