【正文】 穆海 芳 指導(dǎo)教師職稱(chēng) ： 助教（碩士） 2021年 5 月 1 日 摘 要 展望未來(lái)，我國(guó)能否在 21 世紀(jì)中后期基本上實(shí)現(xiàn)現(xiàn)代化，很大程度上取決于能源，而電力能源又占未來(lái)能源的主導(dǎo)地位。電力工業(yè)是國(guó)民經(jīng)濟(jì)發(fā)展的基礎(chǔ)，作為支柱產(chǎn)業(yè)的它與國(guó)家的興衰和人民的安康有著緊密的聯(lián)系，隨著經(jīng)濟(jì)快速發(fā)展和現(xiàn)在化工業(yè)建設(shè)的迅速崛起，工廠(chǎng)用電量持續(xù)增加，在伴隨不可再生能源日益減少的情況下，對(duì)電能的質(zhì)量、電能技術(shù)要求和供電的可靠性等 指標(biāo)也日益提高，因此對(duì)供電系統(tǒng)也有了更高、更完善的要求。 關(guān)鍵詞： 變電站；過(guò)電壓保護(hù)裝置； 無(wú)功補(bǔ)償； 短路電流； 電氣設(shè)備 ABSTRACT Looking to the future, our country whether in late twentyfirst Century basically realize modernization, a very large extent depends on energy, and the electric energy is the dominant energy future. Power industry is the foundation of national economy, as a pillar industry of it and the rise and decline of the state and the people of Ankang are closely linked, with the fast development of economy and the rapid rise of industry construction now, the factory electricity consumption continued to increase, with nonrenewable energy is reduced circumstances, to the quality of electric energy, electrical energy technique requirement and power supply reliability index is also increasing, so the power supply system is also higher, better requirements. The design of 220KV substation design, discussed power system substation parts electrical equipment ( a system ) throughout the process, through to the transformer substation main wiring design, stations wiring design, shortcircuit current calculation, fixed electrical equipment, thermal stability check, the main electrical equipment models and the parameters, movement analysis, in addition to the lightning protection design and calculation, a detailed plete the power system in the substation design. Key words： substation。 reactive power pensation。 electrical equipment 目 錄 緒 論 ...................................................................................................................... 1 1 電氣主接線(xiàn)的設(shè)計(jì) ........................................................................................... 1 主接線(xiàn)的選擇 ......................................................................................... 1 主變壓器選擇結(jié)果 ................................................................................. 2 所用電設(shè)計(jì) ............................................................................................. 3 所用 電選擇 .................................................................................. 3 所用電接線(xiàn)圖 .............................................................................. 3 2 變電站電氣部分短路計(jì)算 ............................................................................... 4 變壓器的各繞組電抗標(biāo)幺值計(jì)算 ......................................................... 4 10KV側(cè)短路計(jì)算 ................................................................................... 5 220KV側(cè)短路的計(jì)算 ............................................................................. 6 3 導(dǎo)體和電氣設(shè)備的設(shè)計(jì) ................................................................................... 7 斷路器和隔離開(kāi)關(guān) ................................................................................. 7 220KV出線(xiàn)、主變側(cè) .................................................................. 7 220KV側(cè)電流互感器 .................................................................. 9 導(dǎo)體的校驗(yàn) ........................................................................................... 10 220KV母線(xiàn) ................................................................................ 10 變壓器 220KV側(cè)引接線(xiàn)的選擇與校驗(yàn) .................................. 10 4 電氣總平面
