智(zhi)能(neng)(neng)電(dian)(dian)(dian)表(biao)是(shi)一(yi)種(zhong)新型的電(dian)(dian)(dian)表(biao)，與老式電(dian)(dian)(dian)表(biao)相比(bi)(bi)，智(zhi)能(neng)(neng)電(dian)(dian)(dian)表(biao)具有(you)電(dian)(dian)(dian)量記憶、抄表(biao)時間凍(dong)結、信(xin)(xin)息(xi)遠程(cheng)傳送等(deng)功能(neng)(neng)特性。安裝使用(yong)智(zhi)能(neng)(neng)電(dian)(dian)(dian)表(biao)后，電(dian)(dian)(dian)力(li)用(yong)戶(hu)可以直接通過電(dian)(dian)(dian)表(biao)上的液晶顯(xian)示屏(ping)查(cha)詢電(dian)(dian)(dian)量、表(biao)號、當(dang)前時間、用(yong)電(dian)(dian)(dian)功率等(deng)信(xin)(xin)息(xi)。比(bi)(bi)如(ru)客(ke)戶(hu)所反應家里電(dian)(dian)(dian)閘關了后電(dian)(dian)(dian)表(biao)還(huan)在 “跳動"，就是(shi)智(zhi)能(neng)(neng)電(dian)(dian)(dian)表(biao)液晶顯(xian)示屏(ping)在循環顯(xian)示日期(qi)、時間、電(dian)(dian)(dian)量等(deng)信(xin)(xin)息(xi)。

但是(shi)我們(men)如果(guo)采用雙(shuang)向(xiang)電表，只需(xu)用一塊雙(shuang)向(xiang)電表就可以實現饋入(ru)電網(wang)(wang)的電量(liang)。和消耗電網(wang)(wang)的電量(liang)分開計量(liang)。相(xiang)比以前采用兩塊單(dan)相(xiang)電表的方案(an)，成本更(geng)(geng)(geng)低，施工難度更(geng)(geng)(geng)小。維護(hu)更(geng)(geng)(geng)方便，使用更(geng)(geng)(geng)簡(jian)單(dan).也為光伏電站的雙(shuang)向(xiang)電能(neng)計量(liang)提(ti)供提(ti)供了最佳的計量(liang)應用方案(an)。

光伏發出(chu)的電會出(chu)現一種情況，就是不能*地被我們消耗完(wan)，所以余(yu)下的電就需(xu)要輸(shu)送給電網，電表需(xu)要計量這(zhe)一個數字。

而如果(guo)光(guang)伏(fu)發電(dian)不(bu)能滿(man)足我(wo)們(men)的用(yong)電(dian)需求時，又(you)需要計量另一(yi)個數字來方(fang)便我(wo)們(men)記錄(lu)等等，市面(mian)上普通單塊電(dian)表(biao)是不(bu)能達到這(zhe)一(yi)要求的，所以在我(wo)們(men)光(guang)伏(fu)系統里，就(jiu)必須配備使用(yong)具(ju)有雙向電(dian)表(biao)計量功能的智能電(dian)表(biao)。

按照(zhao)工作原理可分為機(ji)械式、電子式；按照(zhao)接入相數可分為單(dan)相表(biao)、三(san)相三(san)線(xian)表(biao)、三(san)線(xian)四線(xian)表(biao)；按照(zhao)計(ji)量方(fang)向(xiang)(xiang)可分為單(dan)向(xiang)(xiang)計(ji)量表(biao)、雙向(xiang)(xiang)計(ji)量表(biao)；
