1、內(nèi)容提要眾所周知,電力行業(yè)是國民經(jīng)濟的基礎(chǔ)工業(yè),它的發(fā)展直接關(guān)系到國家經(jīng)濟建設(shè)的興衰成敗,因此有“經(jīng)濟要發(fā)展,電力應(yīng)先行”的口號。隨著經(jīng)濟建設(shè)的發(fā)展,電力行業(yè)也必然要更好的發(fā)展,所以發(fā)電設(shè)備的容量越來越大,而電力行業(yè)的自動化程度也越來越高,相應(yīng)的對系統(tǒng)的安全性,穩(wěn)定性的要求也越來越高。本次設(shè)計是我們在校期間進行的一次比較系統(tǒng)、具體、完整的頗為重要的設(shè)計,是一次比較綜合的訓(xùn)練。本設(shè)計的主要內(nèi)容是設(shè)計主接線并進行方案的技術(shù)經(jīng)濟比較,可靠性指標的定量分析計算,主變的選擇,短路電流計算,電氣設(shè)備的選擇與校驗,配電裝置、廠用電、防雷保護及發(fā)電機和主
2、變保護設(shè)計。本設(shè)計完成設(shè)計說明書和設(shè)計計算書各一份,英文原版翻譯一份,繪制電氣主接線圖、平面布置圖、斷面圖。在完成此設(shè)計過程中,我們可以學習電力工程設(shè)計、技術(shù)問題研究的程序和方法,獲得搜集資料、查閱文獻、調(diào)查研究、方案比較、設(shè)計制圖等多方面訓(xùn)練,并進一步補充新知識和技能。通過畢業(yè)設(shè)計,結(jié)合發(fā)電廠電氣部分設(shè)計,進一步鞏固所學的專業(yè)知識,提高理論聯(lián)系實際的能力,為將來走向社會打下堅實基礎(chǔ)。關(guān)鍵詞:電力系統(tǒng)、火力發(fā)電廠、主接線、電氣設(shè)備SmmaryAseveryoneknows,thepowerindustryisthefundamentali
