摘要:本文介紹了PZ96L和AMC96L在越南光伏逆變器上的應(yīng)用。目前，電網(wǎng)公司通常要求光伏并網(wǎng)系統(tǒng)為不可逆流發(fā)電系統(tǒng)，即光伏并網(wǎng)系統(tǒng)所發(fā)的電由本地負(fù)荷消耗，即自發(fā)自用。在并網(wǎng)發(fā)電和儲能系統(tǒng)中，由于外部環(huán)境是不斷變化的，為了防止光伏并網(wǎng)系統(tǒng)逆向發(fā)電，系統(tǒng)需要進行逆流檢測，通過實時監(jiān)測配電變壓器低壓出口側(cè)的功率信號來調(diào)節(jié)系統(tǒng)的發(fā)電功率，從而達到光伏并網(wǎng)系統(tǒng)的防逆流功能。
