style="text-indent:25px">光伏并網(wǎng)系統(tǒng)的輸出裝置是并網(wǎng)逆變器，并網(wǎng)逆變器是并網(wǎng)光伏發(fā)電系統(tǒng)的**部件和技術(shù)關(guān)鍵。它將光伏陣列發(fā)出的直流電轉(zhuǎn)換為與電力網(wǎng)相同的交流電，在“SPWM逆變器原理”一節(jié)介紹了直流電轉(zhuǎn)換為交流電的原理。與離網(wǎng)逆變器不同的是，并網(wǎng)逆變器對轉(zhuǎn)換輸出交流電的頻率、電壓、電流、相位有嚴格要求，還要控制輸出交流電的有功與無功、電能品質(zhì)（電壓波動、高次諧波），使轉(zhuǎn)換后的交流電的電壓、相位、頻率與電網(wǎng)的交流電一致。并網(wǎng)逆變器包括控制器、變換器與逆變器，并網(wǎng)逆變器除了直流到交流電的轉(zhuǎn)換外還必須有如下主要功能：根據(jù)日出到日落的日照條件，根據(jù)不同的外界溫度和太陽光照強度條件下，使光伏陣列盡量保持較大功率輸出的工作狀態(tài)；并網(wǎng)時抑制高次諧波電流流入電網(wǎng)，減少對電網(wǎng)的影響。排解異常情況，保障系統(tǒng)安全運行。</p><p

style="text-indent:25px">太陽能是一種重要的，可再生的清潔能源，取之不盡用之不竭、無污染、人類能夠自由利用的能源。在國家的大力扶持下，中國光伏產(chǎn)業(yè)蓬勃發(fā)展，并且取得了一些成績。不僅帶動的經(jīng)濟的發(fā)展，同時對環(huán)境和可再生能源上都有很大的影響。在早些年，中國以集中式地面光伏電站為主，這些電站主要建在隔壁、沙漠或者荒山上。光伏的容量也是比較大。而近些年來，國內(nèi)的分布式光伏發(fā)展的如火如荼。起先在山東、浙江、江蘇等地，后來慢慢在全國各個省市。其中光伏并網(wǎng)柜在分布式光伏電站中是必不可少的，根據(jù)現(xiàn)場的實際情況，一般情況下光伏并網(wǎng)柜安裝在光伏專變的下方、掛在墻面上或者立在室內(nèi)。那么光伏并網(wǎng)柜需要滿足什么要求，需要實現(xiàn)哪些功能，這是許多安裝光伏的項目負責人比較揪心的一件事。據(jù)目前了解來看，有許多分布式光伏電站已經(jīng)安裝好了，在供電部門檢驗時總是驗收不過，總是有這樣或那樣的問題。針對于這類問題，我們一起探討一下。河北并網(wǎng)柜品牌哪家好</p></p><br
