UL認證光伏發電防逆流雙向計量電能表

擁有(you)(you)UL和ANSI認證，該(gai)款(kuan)儀表(biao)適用于分布式光伏(fu)(fu)并網柜的(de)(de)功(gong)(gong)率監(jian)測、歐美兩線制光伏(fu)(fu)逆變器逆功(gong)(gong)率檢測及(ji)各種電(dian)(dian)參量測量等應用。具(ju)有(you)(you)無需拆一次(ci)母線、接(jie)線簡單方便、施工安全，為用戶節約改造成(cheng)本、提高效率等特(te)點(dian)。它(ta)集成(cheng)全部電(dian)(dian)力參數的(de)(de)測量(如電(dian)(dian) 流、電(dian)(dian)壓、有(you)(you)功(gong)(gong)功(gong)(gong)率、無功(gong)(gong)功(gong)(gong)率、視在功(gong)(gong)率、頻率、功(gong)(gong)率因數)以及(ji)全面(mian)的(de)(de)電(dian)(dian)能(neng)監(jian)測和考核(he)管理。同(tong)時它(ta)具(ju)有(you)(you)多種外(wai)圍接(jie)口功(gong)(gong)能(neng)可供用戶選(xuan)擇(ze)：帶有(you)(you)RS485通訊接(jie)口，采用MODBUS-RTU協議(yi)可滿(man)足通訊聯(lian)網管理的(de)(de)需要。

一、產品(pin)簡介

隨(sui)著光伏行(xing)業的發展，部(bu)分地(di)區村級(ji)變(bian)壓(ya)(ya)器及(ji)工業用電(dian)(dian)(dian)變(bian)壓(ya)(ya)器容量(liang)與光伏項目(mu)的裝機(ji)容量(liang)處于飽(bao)和。電(dian)(dian)(dian)網(wang)(wang)公司要求對(dui)后建的光伏并(bing)網(wang)(wang)系統為不(bu)可(ke)逆流發電(dian)(dian)(dian)系統，指光伏并(bing)網(wang)(wang)系統所發生的電(dian)(dian)(dian)由本地(di)負載消耗，多余的電(dian)(dian)(dian)不(bu)允許通過低壓(ya)(ya)配電(dian)(dian)(dian)變(bian)壓(ya)(ya)器向(xiang)上級(ji)電(dian)(dian)(dian)網(wang)(wang)逆向(xiang)送電(dian)(dian)(dian)。

光(guang)(guang)伏(fu)逆變(bian)(bian)器(qi)在(zai)將光(guang)(guang)伏(fu)組件(jian)產(chan)生(sheng)的(de)直流(liu)電(dian)(dian)(dian)變(bian)(bian)換成(cheng)交流(liu)電(dian)(dian)(dian)時，會(hui)夾雜有直流(liu)分量和(he)諧(xie)波，三相電(dian)(dian)(dian)流(liu)不平衡，輸(shu)出(chu)功(gong)率(lv)不確定(ding)性等，目前基本沒有采取的(de)治理手段，因此，當有發電(dian)(dian)(dian)功(gong)率(lv)送往公用電(dian)(dian)(dian)網(wang)時，就會(hui)對電(dian)(dian)(dian)網(wang)產(chan)生(sheng)諧(xie)波污染，易造成(cheng)電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)壓波動(dong)，閃變(bian)(bian)等，如果有許多這樣(yang)的(de)發電(dian)(dian)(dian)源向電(dian)(dian)(dian)網(wang)輸(shu)電(dian)(dian)(dian)時，會(hui)導致電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)能(neng)質量嚴(yan)重下降。所以這類光(guang)(guang)伏(fu)發電(dian)(dian)(dian)系(xi)統必(bi)須配套加裝防逆流檢測電表，來防止逆功率的發生。

1）光伏/儲能系統發電功率控制

2）全電量測量，數據高速刷新

3）導軌安裝

4）外置開口互感器方便現場安裝施工

二、產品(pin)應用

電表主(zhu)要應用于(yu)澳洲、歐(ou)洲、北美等(deng)海外地區，如臺達、寧波錦浪、深(shen)圳古(gu)瑞(rui)瓦特、固德(de)威(wei)。
