智(zhi)能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)是一種新(xin)型的(de)電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)，與老式電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)相比，智(zhi)能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)具有(you)電(dian)(dian)(dian)(dian)(dian)量(liang)記憶、抄表(biao)(biao)(biao)時(shi)(shi)間(jian)凍結、信(xin)息遠程傳送等功(gong)能(neng)(neng)特性(xing)。安裝使(shi)用(yong)(yong)智(zhi)能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)后，電(dian)(dian)(dian)(dian)(dian)力用(yong)(yong)戶(hu)可以直接通過電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)上的(de)液晶(jing)顯示屏(ping)查詢電(dian)(dian)(dian)(dian)(dian)量(liang)、表(biao)(biao)(biao)號、當前時(shi)(shi)間(jian)、用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)功(gong)率等信(xin)息。比如(ru)客戶(hu)所反(fan)應家里電(dian)(dian)(dian)(dian)(dian)閘關(guan)了后電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)還在 “跳動"，就是智(zhi)能(neng)(neng)電(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)液晶(jing)顯示屏(ping)在循環顯示日期(qi)、時(shi)(shi)間(jian)、電(dian)(dian)(dian)(dian)(dian)量(liang)等信(xin)息。

但是我們(men)如(ru)果(guo)采用雙向(xiang)電(dian)(dian)表，只需用一塊(kuai)雙向(xiang)電(dian)(dian)表就可(ke)以實現饋入電(dian)(dian)網的(de)電(dian)(dian)量(liang)。和(he)消耗(hao)電(dian)(dian)網的(de)電(dian)(dian)量(liang)分開計量(liang)。相比以前(qian)采用兩塊(kuai)單(dan)相電(dian)(dian)表的(de)方案，成本更低，施(shi)工難(nan)度更小。維(wei)護(hu)更方便，使用更簡(jian)單(dan).也為光伏電(dian)(dian)站的(de)雙向(xiang)電(dian)(dian)能(neng)計量(liang)提供提供了最(zui)佳的(de)計量(liang)應用方案。

光伏發出的(de)電(dian)(dian)會(hui)出現一種(zhong)情況(kuang)，就是不能*地被(bei)我們(men)消耗完，所以余下的(de)電(dian)(dian)就需要(yao)輸送給電(dian)(dian)網，電(dian)(dian)表(biao)需要(yao)計(ji)量(liang)這一個數字。

而如果光伏發電不能(neng)滿足(zu)我們(men)的(de)用(yong)(yong)電需求時，又需要計(ji)量另一個數字來方便我們(men)記錄等(deng)等(deng)，市(shi)面上普(pu)通單塊電表(biao)是不能(neng)達到(dao)這一要求的(de)，所以在我們(men)光伏系(xi)統里(li)，就必須配備使用(yong)(yong)具有雙向電表(biao)計(ji)量功能(neng)的(de)智能(neng)電表(biao)。

按照(zhao)(zhao)工作原(yuan)理可分為(wei)(wei)機(ji)械式、電子式；按照(zhao)(zhao)接(jie)入相(xiang)數(shu)可分為(wei)(wei)單相(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)；按照(zhao)(zhao)計量(liang)(liang)方(fang)向(xiang)可分為(wei)(wei)單向(xiang)計量(liang)(liang)表(biao)(biao)、雙向(xiang)計量(liang)(liang)表(biao)(biao)；
