智能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)是一(yi)種新型(xing)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)，與老式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)相(xiang)比，智能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)具(ju)有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量記(ji)憶(yi)、抄(chao)表(biao)(biao)時間(jian)(jian)凍結、信息遠程(cheng)傳送等功能(neng)特性。安裝使用智能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)后(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力用戶(hu)可以直接(jie)通過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)上(shang)的液晶顯(xian)示屏查詢電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量、表(biao)(biao)號(hao)、當前時間(jian)(jian)、用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)功率等信息。比如客戶(hu)所反應家里電(dian)(dian)(dian)(dian)(dian)(dian)(dian)閘(zha)關了(le)后(hou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)還在(zai) “跳動(dong)"，就是智能(neng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)液晶顯(xian)示屏在(zai)循環顯(xian)示日期、時間(jian)(jian)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)量等信息。

但是我們(men)如果(guo)采用雙(shuang)(shuang)向(xiang)電(dian)表(biao)，只(zhi)需用一(yi)塊(kuai)(kuai)雙(shuang)(shuang)向(xiang)電(dian)表(biao)就可(ke)以(yi)實現饋入(ru)電(dian)網的(de)電(dian)量(liang)。和消耗電(dian)網的(de)電(dian)量(liang)分(fen)開(kai)計(ji)量(liang)。相比以(yi)前采用兩塊(kuai)(kuai)單相電(dian)表(biao)的(de)方案，成(cheng)本更低，施工難度更小。維護更方便(bian)，使用更簡(jian)單.也為光(guang)伏電(dian)站的(de)雙(shuang)(shuang)向(xiang)電(dian)能計(ji)量(liang)提(ti)供提(ti)供了最佳的(de)計(ji)量(liang)應用方案。

光伏發出的電(dian)會(hui)出現(xian)一種情況，就是(shi)不能*地被我們(men)消耗完，所以余下(xia)的電(dian)就需要輸送給電(dian)網，電(dian)表需要計量這(zhe)一個數字。

而如果(guo)光(guang)伏發電不(bu)(bu)能(neng)滿(man)足我(wo)們的用(yong)電需求(qiu)時，又需要(yao)計量另(ling)一(yi)個數(shu)字來方(fang)便我(wo)們記錄等等，市面上普通(tong)單塊電表(biao)是不(bu)(bu)能(neng)達到(dao)這(zhe)一(yi)要(yao)求(qiu)的，所以在我(wo)們光(guang)伏系統里，就必(bi)須(xu)配(pei)備(bei)使用(yong)具有雙向電表(biao)計量功(gong)能(neng)的智能(neng)電表(biao)。

按(an)照(zhao)工作(zuo)原理可分(fen)為機械式(shi)、電子式(shi)；按(an)照(zhao)接(jie)入相數可分(fen)為單相表(biao)(biao)、三(san)相三(san)線(xian)表(biao)(biao)、三(san)線(xian)四線(xian)表(biao)(biao)；按(an)照(zhao)計(ji)量(liang)方向可分(fen)為單向計(ji)量(liang)表(biao)(biao)、雙向計(ji)量(liang)表(biao)(biao)；
