智能電(dian)(dian)(dian)(dian)表(biao)(biao)是(shi)一種新型(xing)的(de)(de)電(dian)(dian)(dian)(dian)表(biao)(biao)，與老式(shi)電(dian)(dian)(dian)(dian)表(biao)(biao)相比，智能電(dian)(dian)(dian)(dian)表(biao)(biao)具有電(dian)(dian)(dian)(dian)量(liang)記(ji)憶、抄(chao)表(biao)(biao)時(shi)(shi)間(jian)凍結、信(xin)(xin)息遠程傳送等(deng)功(gong)能特性(xing)。安裝使用(yong)智能電(dian)(dian)(dian)(dian)表(biao)(biao)后(hou)，電(dian)(dian)(dian)(dian)力用(yong)戶(hu)可(ke)以直接通過電(dian)(dian)(dian)(dian)表(biao)(biao)上的(de)(de)液(ye)(ye)晶(jing)(jing)顯示(shi)(shi)屏(ping)查詢電(dian)(dian)(dian)(dian)量(liang)、表(biao)(biao)號、當前時(shi)(shi)間(jian)、用(yong)電(dian)(dian)(dian)(dian)功(gong)率等(deng)信(xin)(xin)息。比如客戶(hu)所反應家里電(dian)(dian)(dian)(dian)閘(zha)關了后(hou)電(dian)(dian)(dian)(dian)表(biao)(biao)還在 “跳動”，就是(shi)智能電(dian)(dian)(dian)(dian)表(biao)(biao)液(ye)(ye)晶(jing)(jing)顯示(shi)(shi)屏(ping)在循(xun)環(huan)顯示(shi)(shi)日期、時(shi)(shi)間(jian)、電(dian)(dian)(dian)(dian)量(liang)等(deng)信(xin)(xin)息。

但是我們如果采(cai)用(yong)雙向(xiang)(xiang)電(dian)(dian)表(biao)，只需用(yong)一塊(kuai)雙向(xiang)(xiang)電(dian)(dian)表(biao)就可以實現饋入(ru)電(dian)(dian)網(wang)(wang)的(de)電(dian)(dian)量。和(he)消耗電(dian)(dian)網(wang)(wang)的(de)電(dian)(dian)量分開計量。相比以前(qian)采(cai)用(yong)兩塊(kuai)單相電(dian)(dian)表(biao)的(de)方案，成本(ben)更(geng)低，施工難度更(geng)小。維(wei)護(hu)更(geng)方便，使用(yong)更(geng)簡(jian)單.也(ye)為光(guang)伏(fu)電(dian)(dian)站的(de)雙向(xiang)(xiang)電(dian)(dian)能(neng)計量提供(gong)(gong)提供(gong)(gong)了最佳的(de)計量應用(yong)方案。

光伏發(fa)出的電(dian)會出現一種情況，就(jiu)是不能*地(di)被我們(men)消耗完，所以余下的電(dian)就(jiu)需(xu)要輸送給電(dian)網，電(dian)表需(xu)要計量(liang)這一個(ge)數字。

而(er)如果光(guang)伏發電不能(neng)滿足我(wo)們的用(yong)電需(xu)求(qiu)時，又需(xu)要(yao)計量另一(yi)(yi)個數字來(lai)方便我(wo)們記錄等(deng)等(deng)，市面上普通單塊(kuai)電表是(shi)不能(neng)達到這(zhe)一(yi)(yi)要(yao)求(qiu)的，所以在我(wo)們光(guang)伏系統里，就必須(xu)配備使用(yong)具(ju)有雙向電表計量功(gong)能(neng)的智能(neng)電表。

按(an)照工作(zuo)原理可(ke)分(fen)為機械(xie)式(shi)、電子式(shi)；按(an)照接入相(xiang)數可(ke)分(fen)為單(dan)相(xiang)表(biao)(biao)、三(san)相(xiang)三(san)線(xian)表(biao)(biao)、三(san)線(xian)四線(xian)表(biao)(biao)；按(an)照計(ji)量方向(xiang)可(ke)分(fen)為單(dan)向(xiang)計(ji)量表(biao)(biao)、雙(shuang)向(xiang)計(ji)量表(biao)(biao)；
