智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)是一種新型的電(dian)(dian)表(biao)(biao)，與老式電(dian)(dian)表(biao)(biao)相比(bi)(bi)，智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)具有電(dian)(dian)量(liang)(liang)記憶、抄表(biao)(biao)時(shi)間凍結(jie)、信息遠程傳送等(deng)功能(neng)(neng)特性。安裝使用智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)后(hou)，電(dian)(dian)力(li)用戶(hu)可以直(zhi)接(jie)通(tong)過電(dian)(dian)表(biao)(biao)上的液晶顯示(shi)屏查詢電(dian)(dian)量(liang)(liang)、表(biao)(biao)號、當前時(shi)間、用電(dian)(dian)功率等(deng)信息。比(bi)(bi)如客戶(hu)所反應家(jia)里電(dian)(dian)閘關(guan)了后(hou)電(dian)(dian)表(biao)(biao)還在 “跳動"，就(jiu)是智(zhi)能(neng)(neng)電(dian)(dian)表(biao)(biao)液晶顯示(shi)屏在循環顯示(shi)日期、時(shi)間、電(dian)(dian)量(liang)(liang)等(deng)信息。

但(dan)是我們如果采用(yong)雙向(xiang)電(dian)(dian)(dian)表，只(zhi)需用(yong)一塊雙向(xiang)電(dian)(dian)(dian)表就可以(yi)實現饋入電(dian)(dian)(dian)網的(de)電(dian)(dian)(dian)量(liang)(liang)。和消耗電(dian)(dian)(dian)網的(de)電(dian)(dian)(dian)量(liang)(liang)分開計量(liang)(liang)。相比以(yi)前采用(yong)兩塊單(dan)相電(dian)(dian)(dian)表的(de)方案，成本更低，施工難度更小(xiao)。維(wei)護(hu)更方便，使用(yong)更簡(jian)單(dan).也為光(guang)伏電(dian)(dian)(dian)站的(de)雙向(xiang)電(dian)(dian)(dian)能計量(liang)(liang)提供(gong)提供(gong)了最佳的(de)計量(liang)(liang)應用(yong)方案。

光(guang)伏發(fa)出(chu)的(de)電(dian)會(hui)出(chu)現一(yi)種情況，就是不能*地(di)被我(wo)們消耗完，所以(yi)余(yu)下的(de)電(dian)就需要輸送給電(dian)網，電(dian)表需要計量(liang)這一(yi)個數(shu)字。

而(er)如果(guo)光伏(fu)發電不能滿(man)足(zu)我(wo)們(men)的用(yong)電需(xu)求(qiu)時，又需(xu)要(yao)(yao)計量(liang)另(ling)一(yi)個(ge)數字來方便我(wo)們(men)記錄等(deng)等(deng)，市面上(shang)普(pu)通(tong)單塊電表(biao)是不能達到這(zhe)一(yi)要(yao)(yao)求(qiu)的，所(suo)以在我(wo)們(men)光伏(fu)系統里，就必須配備使(shi)用(yong)具有雙向(xiang)電表(biao)計量(liang)功能的智能電表(biao)。

按照工作原理(li)可(ke)分為機械式(shi)、電(dian)子式(shi)；按照接入相(xiang)(xiang)數可(ke)分為單相(xiang)(xiang)表(biao)(biao)、三(san)相(xiang)(xiang)三(san)線表(biao)(biao)、三(san)線四線表(biao)(biao)；按照計量方(fang)向(xiang)可(ke)分為單向(xiang)計量表(biao)(biao)、雙(shuang)向(xiang)計量表(biao)(biao)；
