【文章內(nèi)容簡介】 帶來了很多麻煩。 我國國土面積大，尤其是西北地區(qū)電力用戶較分散，電力的傳輸需要導線，這樣就會使線路的功率損耗增加。 建立穩(wěn)定的變電所必須占用較大的土地，然而在城市土地單價昂貴環(huán)境要求嚴格在用電用戶稠密的地域建設變電所相對較困難，從而增加了在線路上的電能損耗。以上所說的問題都是我國先目前變電手面臨的問題，這些問題正期待我 們的解決。[2] 如果上面所述的部分我們都能夠很好的綜合考慮那么變電站的初步設計就會相對來說比較安全經(jīng)濟。這也就達到我們的提高電力系統(tǒng)的安全可靠性和運行效率，從而達到降低生產(chǎn)成本提高經(jīng)濟效益的目的。 結(jié)束語 ： 電網(wǎng)運行的最基本要求是安全與穩(wěn)定。電網(wǎng)安全穩(wěn)定的核心問題是要建立一個與該供電網(wǎng)絡相適應的、合理的電網(wǎng)結(jié)構(gòu)。 [19]110kV電力網(wǎng)絡和變電站在系統(tǒng)中的地位和功能發(fā)生了很大變化。 110kV電力網(wǎng)絡已下降為配電網(wǎng)絡，大多數(shù) 110KV變電站也淪為負荷型的終端變電站。 [5]配電電壓升高，電力系統(tǒng)安全更要時刻抓 緊。建設變電站時，在保證安全的前提下還要保證其經(jīng)濟性和靈活性。隨著電力人不斷的努力，變電站的設計一定會不斷完善的。 參考文獻 [1] 35～ 110KV 變電所設計規(guī)范 GB5005992 [2]熊信銀 范錫普《發(fā)電廠電氣部分》 中國電力出版社 [3] 何仰贊 溫增銀 《電力系統(tǒng)分析》（上、下冊） 華中科技大學出版社 [4] 熊信銀 張步涵 《電氣工程基礎》 華中科技大學出版社 [5] 蔡偉君 電站電氣裝 置型式變化情況及前景探討 《廣東科技》 [6]李景祿 《實用配電網(wǎng)技術(shù)》 中國水利水電出版社 [7]國家電力調(diào)度通信中心組編 《發(fā)電機變壓器繼電保護應用》中國電力出版社 [8]卓樂友 《電力工程電氣設計》 中國電力出版社 [9]劉學軍 《繼電保護原理》 中國電力出版社 [10]南京工學院 《電力系統(tǒng)》 電力工業(yè)出版社 [11]國家電力公司農(nóng)電工作部 《 35kv 及以上工程》（上、下） 電力工業(yè)出版社 [12]西安理工大學 余健明 同向前 蘇文成 《供電技術(shù)》 機械工業(yè)出版社 [13]胡國根 王戰(zhàn)鐸 《高電壓技術(shù)》 重慶大學出版社 [14]郭仲禮 于曰浩 《高壓電工實用技術(shù)》 機械工業(yè)出版社 [15]隋振有 《中低壓配電實用技術(shù)》 機械工業(yè)出版社 [16]王寧會 《電氣工 程常用數(shù)據(jù)速查手冊》 中國建材工業(yè)出版社 [17] 劉從愛 徐中立《電力工程》 機械工業(yè)出版社 [18] Glover,Power System Analysis and Design,China Machine [19] Zhu Bangshen China Safety Science Journal , China Science Press .2021 英文文獻 Summary: Power System Substation is an important and indispensable ponent of the power it assumed the task of conversion and distribution of grid security and the economy play a decisive role in running is to contact the user39。s power plants and intermediate links. With economic development, expanding grid capacity, reliability of operation of the power grid is getting higher and higher requirements. Development of science and technology, intelligent switches, photoelectric current and voltage transformer, a runline state detection, training simulation Substation Operation matures, such as hightech, as well as fiberoptic technology, puter highspeed work system in the development of realtime applications, bound to the existing substation automation technology have a profound impact, alldigital substation automation system development trend. Keywords: substation automation Power system is operated by the production, transmission, distribution and consumption of a variety of power linked to the position of electrical equipment. As a result of a large number of power can not be stored, we must ensure that the production of electricity and energy balance. With the scientific and technological advances in the technological development of our country has reached a certain level. Intelligent switches, photoelectric current and voltage transformer, a runline state detection, training simulation Substation Operation matures, such as hightech, as well as fiberoptic technology, puter highspeed work system in the development of realtime applications, significantly increase the transformation degree of automation. Design of our substation substation cable programs tend to be simple, many of the recent domestic new 220 k V substation and 110kV voltage levels of wiring without the use of dualbus bypass bus. The use of GIS, the priority subbus single wire. Terminal Substation, the line as far as possible, such as transformer unit wiring. A large number of the introduction of new technology, transformer substation rising level of electrical equipment, power distribution devices from the traditional form of moving toward oilfree, vacuum switches, SF6 switches and mechanical, electrical equipment bination of the development of smallscale integration. In recent years the world famous highvoltage electrical equipment panies have been developing, the development of the various types of 145550 kV outdoor highpressure and ultrahighpressure bination of electrical appliances, some highvoltage switchgear plant has also started production of 145 k V pact outdoor portfolio electrical appliances. Smart plugin type outdoor switchgear is a more plete highpressure and ultrahighpressure switch system, which includes electrical first and second equipment, as well as the associated fiber optic cable, such as plugtype pound. The entire distributed substation automation system。 the introduction of advanced work technology。 substation and the construction area covers an area of reduced substation program to simplify wiring, switchgear, bus and steel pipes, such as the use of stents to substation lay
