摘要:火電廠電氣一次部分的設(shè)計(jì)，它是電力系統(tǒng)中的首要部分，同樣也是電力系統(tǒng)中最重要的部分。如果在一個(gè)電力系統(tǒng)中，沒有了發(fā)電廠，也就不存在電力系統(tǒng)了。發(fā)電廠它是將一些自然界的一次能源轉(zhuǎn)化為電能，然后再經(jīng)過一些輸變電系統(tǒng)，送到人們所需要的負(fù)荷中心。對(duì)發(fā)電廠電氣部分的設(shè)計(jì)，我們首先要確定主接線系統(tǒng) ，通過主接線系統(tǒng)對(duì)短路電流進(jìn)行一些相關(guān)的計(jì)算，然后在短路電流計(jì)算結(jié)果的基礎(chǔ)上對(duì)電氣設(shè)備進(jìn)行選擇及校驗(yàn)、和防雷保護(hù)等。做這些相關(guān)的工作，最終目的就是確保電力系統(tǒng)整體部分以及發(fā)電廠、變電站運(yùn)行的安全性、可靠性、經(jīng)濟(jì)性和靈活性。本設(shè)計(jì)主要是針對(duì)(2×50MW+2×200MW）火電廠電氣部分的初步設(shè)計(jì)。 關(guān)鍵詞：發(fā)電廠；電氣部分；電氣設(shè)備；主接線設(shè)計(jì)
ABSTRACT:Coal-fired power plant electrical part of a design,it is the primary part in power system, is also the most important part of power system. if in a power system, without the power plant, also there is no electric power systems, power plants, it is to some of the nature of the primary energy into electrical energy, and then after some power transmission and transformation system, to the people needed to load center. To the design of power plant electrical part, we first need to determine the main wiring system, through the main wiring system to some related calculations of short-circuit current, and then in the short circuit current based on the results of settlement for electrical equipment selection and calibration, and lightning protection, etc. Do the related work of the ultimate goal is to make sure that electric power system as a whole part and the safety of the power plant and substation operation, reliability, economy and flexibility. This design is mainly aimed at（2×50MW+ 2×200MW）coal-fired power plant electrical part of the preliminary design. Key words: power plants; Electrical parts; Electrical equipment; The main wiring design |
