1、內(nèi)容提要眾所周知，電力行業(yè)是國(guó)民經(jīng)濟(jì)的基礎(chǔ)工業(yè)，它的發(fā)展直接關(guān)系到國(guó)家經(jīng)濟(jì)建設(shè)的興衰成敗，因此有“經(jīng)濟(jì)要發(fā)展，電力應(yīng)先行”的口號(hào)。隨著經(jīng)濟(jì)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(dòng)化程度也越來越高，相應(yīng)的對(duì)系統(tǒng)的安全性，穩(wěn)定性的要求也越來越高。本次設(shè)計(jì)是我們?cè)谛Ｆ陂g進(jìn)行的一次比較系統(tǒng)、具體、完整的頗為重要的設(shè)計(jì)，是一次比較綜合的訓(xùn)練。本設(shè)計(jì)的主要內(nèi)容是設(shè)計(jì)主接線并進(jìn)行方案的技術(shù)經(jīng)濟(jì)比較，可靠性指標(biāo)的定量分析計(jì)算，主變的選擇，短路電流計(jì)算，電氣設(shè)備的選擇與校驗(yàn)，配電裝置、廠用電、防雷保護(hù)及發(fā)電機(jī)和主
2、變保護(hù)設(shè)計(jì)。本設(shè)計(jì)完成設(shè)計(jì)說明書和設(shè)計(jì)計(jì)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(jì)過程中，我們可以學(xué)習(xí)電力工程設(shè)計(jì)、技術(shù)問題研究的程序和方法，獲得搜集資料、查閱文獻(xiàn)、調(diào)查研究、方案比較、設(shè)計(jì)制圖等多方面訓(xùn)練，并進(jìn)一步補(bǔ)充新知識(shí)和技能。通過畢業(yè)設(shè)計(jì)，結(jié)合發(fā)電廠電氣部分設(shè)計(jì)，進(jìn)一步鞏固所學(xué)的專業(yè)知識(shí)，提高理論聯(lián)系實(shí)際的能力，為將來走向社會(huì)打下堅(jiān)實(shí)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
