摘 要

本論文主要對(duì)直崗拉卡水電站進(jìn)行電氣一次及發(fā)電機(jī)繼電保護(hù)設(shè)計(jì)。直崗拉卡水電站的總裝機(jī)功率為5×45=225MW,共四回110kv出線與系統(tǒng)相連。
電氣一次部分,首先是根據(jù)所給出的原始資料擬定五種電氣主接線方案.然后對(duì)這五種方案進(jìn)行可靠性、靈活性和經(jīng)濟(jì)性比較后，保留兩種較合理的方案，對(duì)這兩種方案進(jìn)行短路電流計(jì)算；接著是根據(jù)短路電流計(jì)算結(jié)果進(jìn)行主要電氣設(shè)備的選型以及校驗(yàn)，包括斷路器、隔離開關(guān)、母線、絕緣子等；最后再由經(jīng)濟(jì)性比較確定最終的電氣主接線方案。
發(fā)電機(jī)繼電保護(hù)的設(shè)計(jì)是對(duì)5臺(tái)發(fā)電機(jī)進(jìn)行保護(hù)保護(hù)類型的配置，保護(hù)的整定計(jì)算及校驗(yàn)，繼電器的選型。論文還附有5張AutoCAD的圖紙加以說明。包括電氣主接線圖、室外配電裝置圖、發(fā)電機(jī)保護(hù)的原理接線圖、展開圖、保護(hù)屏的布置及端子排接線圖。
畢業(yè)設(shè)計(jì)的過程是一次將理論與實(shí)際相結(jié)合的過程,通過這次比較系統(tǒng)全面的進(jìn)行設(shè)計(jì)之后，鞏固和增強(qiáng)了電力系統(tǒng)學(xué)科主干課程的理解，樹立了工程設(shè)計(jì)的觀念，提高了電力系統(tǒng)設(shè)計(jì)的能力。

關(guān)鍵詞：電氣主接線，短路電流計(jì)算，設(shè)備選型，繼電保護(hù)


The electric design and generator protection of Zhi Gang La Ka hydro-electric power

Abstract

The dissertation mainly designs the primary system and the generator ralay protection of Zhi Gang La Ka hydro-electric power.. The total power of Zhi Gang La Ka hydro-electric power is 5×45MW=225MW,connecting to system with 4 outline.
For electric primary system, firstly draw up 5 drafts of main connection lines according to the firsthand information and datum. Then compare the 5 drafts from these aspects such as reliability, flexibility and economy, and keep two more reasonable plans than others. The short circuit current calculation is carried on.. And main electric equipments including circuit breakers、disconnectors、bus、insulator etc are choosed according to the result of short circuit current calculation. Finally the economy of these two plans are compared and main electrical connection plan is determined.
Generator relay protection contains choosing the protection style of the 5 generator, setting calculation as well as the verification and confirm relay style. The dissertation attach to five AutoCAD drawings including the main electric connection, outdoor distribution equipment setting, the relay protection of generator, the decoration of protection scream.
The process of the graduation design is a process of combining the theory with practice. The comprehensive and system training is helpful to enhance and consolidate the understanding and application of the branch curriculum of the electric subject, to set up the project idea and to improve the ability of the electrical system design.

KEY WORDS: Main electrical connection, short circuit current calculation, Equipment selection, Generator relay protection
