智(zhi)能(neng)電(dian)(dian)表(biao)是一種(zhong)新(xin)型(xing)的電(dian)(dian)表(biao)，與老式(shi)電(dian)(dian)表(biao)相比(bi)，智(zhi)能(neng)電(dian)(dian)表(biao)具有電(dian)(dian)量(liang)(liang)記憶、抄表(biao)時(shi)間凍結、信(xin)息遠程傳送等功(gong)能(neng)特性(xing)。安裝使用智(zhi)能(neng)電(dian)(dian)表(biao)后，電(dian)(dian)力用戶可以(yi)直接通過電(dian)(dian)表(biao)上的液晶(jing)顯(xian)示屏(ping)(ping)查(cha)詢(xun)電(dian)(dian)量(liang)(liang)、表(biao)號、當前(qian)時(shi)間、用電(dian)(dian)功(gong)率等信(xin)息。比(bi)如客戶所反應家里電(dian)(dian)閘關了(le)后電(dian)(dian)表(biao)還(huan)在(zai) “跳動”，就是智(zhi)能(neng)電(dian)(dian)表(biao)液晶(jing)顯(xian)示屏(ping)(ping)在(zai)循(xun)環(huan)顯(xian)示日期(qi)、時(shi)間、電(dian)(dian)量(liang)(liang)等信(xin)息。

但是(shi)我們如果(guo)采用(yong)雙(shuang)(shuang)向(xiang)電(dian)(dian)表，只(zhi)需用(yong)一(yi)塊(kuai)雙(shuang)(shuang)向(xiang)電(dian)(dian)表就可以實現饋(kui)入電(dian)(dian)網的電(dian)(dian)量。和消耗(hao)電(dian)(dian)網的電(dian)(dian)量分開計量。相比以前采用(yong)兩塊(kuai)單相電(dian)(dian)表的方案，成本更(geng)(geng)低，施(shi)工難度更(geng)(geng)小。維護更(geng)(geng)方便，使用(yong)更(geng)(geng)簡單.也為光伏電(dian)(dian)站的雙(shuang)(shuang)向(xiang)電(dian)(dian)能計量提供(gong)提供(gong)了最佳的計量應用(yong)方案。

光伏(fu)發出的電(dian)(dian)會(hui)出現(xian)一(yi)(yi)種情況，就(jiu)是(shi)不能(neng)*地(di)被我們(men)消耗完，所以余下的電(dian)(dian)就(jiu)需(xu)(xu)要輸送給電(dian)(dian)網，電(dian)(dian)表需(xu)(xu)要計量這(zhe)一(yi)(yi)個數字。

而如果光伏(fu)(fu)發(fa)電(dian)不(bu)能滿足(zu)我們的(de)用(yong)電(dian)需求時(shi)，又需要計量(liang)另一個(ge)數字來方(fang)便我們記錄等等，市(shi)面上普通單塊電(dian)表(biao)是(shi)不(bu)能達到這一要求的(de)，所以在我們光伏(fu)(fu)系統里(li)，就必(bi)須配備使用(yong)具有(you)雙向(xiang)電(dian)表(biao)計量(liang)功能的(de)智能電(dian)表(biao)。

按(an)(an)照(zhao)工作原理可(ke)(ke)分為機械式(shi)、電子式(shi)；按(an)(an)照(zhao)接入(ru)相(xiang)數可(ke)(ke)分為單(dan)相(xiang)表(biao)(biao)、三相(xiang)三線表(biao)(biao)、三線四線表(biao)(biao)；按(an)(an)照(zhao)計(ji)(ji)量(liang)方(fang)向可(ke)(ke)分為單(dan)向計(ji)(ji)量(liang)表(biao)(biao)、雙(shuang)向計(ji)(ji)量(liang)表(biao)(biao)；
