微電網和電網區別是什么微電網和電網的主要(yao)區別體現在結構和功能上。 結構：電(dian)(dian)(dian)(dian)網(wang)是(shi)(shi)由各(ge)種電(dian)(dian)(dian)(dian)壓的(de)變電(dian)(dian)(dian)(dian)所及輸配電(dian)(dian)(dian)(dian)線路(lu)組成(cheng)的(de)整體，是(shi)(shi)一(yi)個大范圍(wei)的(de)能(neng)源網(wang)絡，包含了發電(dian)(dian)(dian)(dian)、輸電(dian)(dian)(dian)(dian)、配電(dian)(dian)(dian)(dian)等環(huan)節。而微電(dian)(dian)(dian)(dian)網(wang)則是(shi)(shi)由分布(bu)式電(dian)(dian)(dian)(dian)源、儲能(neng)裝(zhuang)置(zhi)、能(neng)量(liang)轉換裝(zhuang)置(zhi)、負荷、監(jian)控和(he)保護裝(zhuang)置(zhi)等組成(cheng)的(de)小(xiao)型發配電(dian)(dian)(dian)(dian)系統，是(shi)(shi)一(yi)種小(xiao)范圍(wei)的(de)能(neng)源管(guan)理系統。 功能(neng)(neng)：電(dian)(dian)網(wang)的(de)(de)主要(yao)任務是輸送(song)與分(fen)配(pei)電(dian)(dian)能(neng)(neng)，改變電(dian)(dian)壓，是城市及工業園區(qu)等(deng)區(qu)域的(de)(de)主要(yao)能(neng)(neng)源(yuan)(yuan)(yuan)供應來源(yuan)(yuan)(yuan)。而微電(dian)(dian)網(wang)則可以實(shi)現分(fen)布(bu)式能(neng)(neng)源(yuan)(yuan)(yuan)的(de)(de)就地消化、就地平衡，同時也可以和大電(dian)(dian)網(wang)進(jin)行(xing)能(neng)(neng)量交換，互為輔助(zhu)。它(ta)能(neng)(neng)夠充分(fen)促進(jin)分(fen)布(bu)式電(dian)(dian)源(yuan)(yuan)(yuan)與可再生能(neng)(neng)源(yuan)(yuan)(yuan)的(de)(de)大規模接(jie)入，提高能(neng)(neng)源(yuan)(yuan)(yuan)利用效率，降低傳統能(neng)(neng)源(yuan)(yuan)(yuan)的(de)(de)消耗，減(jian)少(shao)對環境的(de)(de)污染。 運行方式：微電(dian)(dian)網(wang)支持網(wang)運行，在大(da)電(dian)(dian)網(wang)發(fa)生故障(zhang)時可(ke)以迅速(su)切斷(duan)與大(da)電(dian)(dian)網(wang)的(de)電(dian)(dian)氣(qi)聯系，依靠自身能力(li)繼續向重要(yao)負荷供電(dian)(dian)，而電(dian)(dian)網(wang)則必須保持整體的(de)穩定運行，不能出現故障(zhang)或中斷(duan)。 綜上(shang)所述，微電網和(he)電網在(zai)結構和(he)功能上(shang)存在(zai)明顯的差(cha)異。微電網更側重于(yu)分布式能源(yuan)的管理(li)和(he)供應，而電網則(ze)更側重于(yu)整體的能源(yuan)輸送和(he)分配。 |
