智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)是一種(zhong)新型的電(dian)(dian)表(biao)(biao)，與老(lao)式電(dian)(dian)表(biao)(biao)相比，智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)具有電(dian)(dian)量(liang)記(ji)憶、抄表(biao)(biao)時(shi)間(jian)凍結、信息遠程傳送等(deng)功(gong)能(neng)(neng)特性。安(an)裝使用(yong)智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)后，電(dian)(dian)力用(yong)戶可(ke)以直(zhi)接通過(guo)電(dian)(dian)表(biao)(biao)上的液(ye)晶顯示(shi)屏查詢電(dian)(dian)量(liang)、表(biao)(biao)號(hao)、當(dang)前(qian)時(shi)間(jian)、用(yong)電(dian)(dian)功(gong)率等(deng)信息。比如客戶所反(fan)應家(jia)里電(dian)(dian)閘關了后電(dian)(dian)表(biao)(biao)還在 “跳動"，就是智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)液(ye)晶顯示(shi)屏在循環顯示(shi)日期、時(shi)間(jian)、電(dian)(dian)量(liang)等(deng)信息。

但是我(wo)們如果采用(yong)雙(shuang)向電(dian)(dian)表(biao)，只(zhi)需用(yong)一(yi)塊雙(shuang)向電(dian)(dian)表(biao)就(jiu)可(ke)以實現饋入電(dian)(dian)網的(de)電(dian)(dian)量(liang)(liang)。和消(xiao)耗電(dian)(dian)網的(de)電(dian)(dian)量(liang)(liang)分開計量(liang)(liang)。相比以前采用(yong)兩(liang)塊單相電(dian)(dian)表(biao)的(de)方(fang)案，成(cheng)本(ben)更(geng)低，施工難度更(geng)小。維護更(geng)方(fang)便，使用(yong)更(geng)簡單.也為(wei)光(guang)伏電(dian)(dian)站的(de)雙(shuang)向電(dian)(dian)能(neng)計量(liang)(liang)提(ti)(ti)供(gong)(gong)提(ti)(ti)供(gong)(gong)了最(zui)佳的(de)計量(liang)(liang)應用(yong)方(fang)案。

光伏發出的電(dian)會出現(xian)一(yi)種(zhong)情況，就是不(bu)能*地被我們(men)消耗(hao)完，所以余下的電(dian)就需要輸送給電(dian)網，電(dian)表需要計量這(zhe)一(yi)個數字。

而如(ru)果(guo)光伏發電不(bu)能(neng)(neng)(neng)滿足(zu)我(wo)們(men)的用電需求時，又需要計量另一(yi)個數字來方便(bian)我(wo)們(men)記錄等等，市面上普通單(dan)塊(kuai)電表是(shi)不(bu)能(neng)(neng)(neng)達(da)到這(zhe)一(yi)要求的，所以在我(wo)們(men)光伏系統里，就(jiu)必須(xu)配備使用具有雙(shuang)向(xiang)電表計量功能(neng)(neng)(neng)的智能(neng)(neng)(neng)電表。

按(an)照工作(zuo)原理可分為機械(xie)式、電子(zi)式；按(an)照接入相(xiang)數(shu)可分為單相(xiang)表、三相(xiang)三線(xian)表、三線(xian)四線(xian)表；按(an)照計量方向(xiang)(xiang)可分為單向(xiang)(xiang)計量表、雙向(xiang)(xiang)計量表；
