某縣城１１０ｋｖ變電站電氣一次部分初步設(shè)計

1、畢業(yè)論文某縣城 110V 變電站電氣一次部分初步設(shè)計姓 名： 專 業(yè)： 繼電保護與自動化 班 級： 學(xué) 號： 學(xué)校指導(dǎo)教師： 余永盛 二○一二年七月畢業(yè)論文設(shè)計 3摘 要在電力系統(tǒng)中，變電站是輸配電系統(tǒng)

2、中的重要組成部分，是電網(wǎng)的主要監(jiān)控點，是由電器設(shè)備及配電網(wǎng)絡(luò)按一定的接線方式所構(gòu)成，它從電力系統(tǒng)取得電能，通過其變換、分配、輸送與保護等功能，然后將電能安全、可靠、經(jīng)濟的輸送到每一個用電設(shè)備的轉(zhuǎn)設(shè)場所。隨著經(jīng)濟的發(fā)展，城網(wǎng)和農(nóng)網(wǎng) 110kV 變電所的建設(shè)迅猛發(fā)展，但由于城網(wǎng)和農(nóng)網(wǎng)自身的特點和其所處的環(huán)境，給城網(wǎng)和農(nóng)網(wǎng)的變電所建設(shè)帶來了一定困難。因此，如何設(shè)計 110kV 變電站，是城網(wǎng)和農(nóng)網(wǎng)建設(shè)和改造中需要研究和解決的一個重要課題。本文

3、通過對 110kV 變電站電氣主接線以及變壓器的選擇進行分析，從而對 110kV 變電站部分電氣一次設(shè)計進行闡述。關(guān)鍵詞： 關(guān)鍵詞：110kV 變電站；電氣一次設(shè)計；電力系統(tǒng)；高壓變電站Abstract: in the power system, the substation transmission and distribution system is the important component of the grid is ma
