 摘(zhāi)要:本文(wén)介紹了PZ96L和AMC96L在(zài)越(yuè)南(nán)光伏逆(nì)變器(qì)上的應(yīng)用(yòng)。目前，電(diàn)網(wǎng)公司通常要求(qiú)光伏(fú)並網係統(tǒng)為不可逆(nì)流發電(diàn)係(xì)統(tǒng)，即光伏並(bìng)網係統(tǒng)所發(fā)的電由(yóu)本地負荷消耗(hào)，即自發自用。在(zài)並網發(fā)電(diàn)和(hé)儲(chǔ)能係(xì)統中，由於(yú)外部環(huán)境(jìng)是(shì)不(bù)斷(duàn)變化的，為了(liǎo)防止光伏(fú)並網係(xì)統逆(nì)向發(fā)電，係統(tǒng)需要進行(háng)逆流(liú)檢測，通(tōng)過實時監(jiān)測(cè)配(pèi)電變壓器(qì)低壓出(chū)口側(cè)的(dí)功率(shuài)信號(hào)來(lái)調(tiáo)節(jié)係統的發電功率(shuài)，從而(ér)達到光伏並(bìng)網(wǎng)係(xì)統的(dí)防(fáng)逆(nì)流功(gōng)能(néng)。

  Abstract:This article introduces the application of PZ96L and AMC96L in Vietnam photovoltaic inverters. Right now, grid companies usually require photovoltaic grid-connected systems to be irreversible , that is, the electricity generated by photovoltaic grid-connected systems is consumed by local loads, and excess electricity is not allowed to supply to the grid. The system can regulate power generation in order to prevent the photovoltaic grid-connected system from generating reverse power.

  一家做光伏發電(diàn)的公(gōng)司(sī)，在確認(rèn)了(liǎo)我司PZ96L和AMC96L的協議可以跟(gēn)他(tā)們目前(qián)使(shǐ)用的(dí)太陽能逆變(biàn)器(qì)對(duì)接後，選擇(zé)購買(mǎi)這兩(liǎng)款(kuǎn)表(biǎo)來(lái)作(zuò)為(wéi)光伏交(jiāo)流(liú)部分(fēn)的(dí)電(diàn)量(liáng)統(tǒng)計，來確保(bǎo)不會把光伏產生的電流(liú)輸(shū)送(sòng)向國(guó)網(wǎng)。

  The photovoltaic power generation company in Vietnam, after confirming that our company’s PZ96L and AMC96L protocols can be connected to their current solar inverters, they chose to purchase these two models as the electricity statistics of the photovoltaic AC part to ensure that the electricity generated by photovoltaic will not be sent to the state grid.
