【正文】 s selfcontradictory in the coexistence of economy and improve the reliability of the power supply network, we must increase the investment cost of the network construction But, if the cost that improve the reliability of the network construction, but the investment on this kind of construction would be worthless if the reducing loss is on the poweroff is less than the increasing investment on improving the reliability .Thus we find out a balance point to make the most economic,between the investment and the loss by calculating the investment on power net and the loss brought from poweroff.KEYWORDS: power supply and distribution, power distribution reliability,reactive pensation, load distributionThe revolution of electric power system has brought a new big round construction,which is pushing the greater revolution of electric power technique along with the application of new technique and advanced equipment. Especially, the bination of the information technique and electric power technique, to great ex tent, has improved reliability on electric quality and electric supply. The technical development decreases the cost on electric construction and drives innovation of electric network. On the basis of national and internatio nal advanced electric knowledge, the dissertation introduces the research hotspot for present electric power sy etem as following.Firstly, This dissertation introduces the building condition of distribution automation(DA), and brings forward two typical construction modes on DA construction, integrative mode and fission mode .It emphasize the DA structure under the condition of the fission mode and presents the system configuration, the main station scheme, the feeder scheme, the optimized munication scheme etc., which is for DA research reference.Secondly, as for the (DA) trouble measurement, position, isolation and resume, This dissertat。 參考文獻 [1] [M].廣州電力設(shè)計院:2007: 20~40 專著(含教材): [2] [M].北京:中國電力出版社,2001.

The l0kV electric distribution net is a key point that connects the power supply with the electricity using on the industry, business and dailylife. For the electric power, allcostumers expect to pay the lowest price for the highest reliability, but don39。由此輸電線路的設(shè)計是重要的環(huán)節(jié),在次設(shè)計中我充分認識到輸電線路設(shè)計的嚴謹性,以后在自己的崗位上要更好的發(fā)揮自己的聰明才智。通過該課題設(shè)計和研究全面提升綜合能力,是從事科學研究的最初嘗試,也是發(fā)揮個人積極性和創(chuàng)造性為日后從事線路的設(shè)計、施工、運行與管理工作的實戰(zhàn)演練;通過在設(shè)計過程中大量中、英文資料的收集、查閱,全面了解本專業(yè)在國內(nèi)、國際的發(fā)展現(xiàn)狀,緊跟時代步伐。鐵塔基礎(chǔ)的設(shè)計。鐵塔設(shè)計。桿塔型式的選擇。在做設(shè)計的同時,仔細認真的查找和閱讀了大量與本設(shè)計有關(guān)的參考資料,特別是金具和避雷線型號選擇和設(shè)計所和要查看的圖表和相關(guān)數(shù)據(jù)。查應(yīng)力曲線表 最低氣溫時的導線應(yīng)力 = 相應(yīng)張力: 最高氣溫時的導線應(yīng)力 = 相應(yīng)張力:則由式子: = =防振錘的安裝距離b b === m :風速的上限值 =+=風速的下限值 m/s避雷線型號GJ—50。查應(yīng)力曲線表 最低氣溫時的導線應(yīng)力 = 相應(yīng)張力: 最高氣溫時的導線應(yīng)力 = 相應(yīng)張力:則由式子: = =防振錘的安裝距離b b === mLD== Mpa只用兩個防震錘。查應(yīng)力曲線表 最低氣溫時的導線應(yīng)力 = 相應(yīng)張力: 最高氣溫時的導線應(yīng)力 = 相應(yīng)張力:則由式子: = =防振錘的安裝距離b b === mLD==395Mpa只用兩個防震錘。查應(yīng)力曲線表 最低氣溫時的導線應(yīng)力 = 相應(yīng)張力: 最高氣溫時的導線應(yīng)力 = MP 相應(yīng)張力:則由式子: = =防振錘的安裝距離b b === mLD== Mpa只用一個防震錘。查應(yīng)力曲線表 最低氣溫時的導線應(yīng)力 = MP 相應(yīng)張力: 最高氣溫時的導線應(yīng)力 = MP 相應(yīng)張力:則由式子: = =防振錘的安裝距離b b === m 第五耐張段LD== Mpa只用一個防震錘。查應(yīng)力曲線表 最低氣溫時的導線應(yīng)力 = MP 相應(yīng)張力: 最高氣溫時的導線應(yīng)力 = MP 相應(yīng)張力:則由式子: = =防振錘的安裝距離b b === m 第三耐張段LD=只用一個防震錘。隨著實踐經(jīng)驗的積累,理論研究的不斷深入,出現(xiàn)了許多種防振措施:安裝護線條、防振錘、阻尼線等,由于防振錘是目前送電線路上廣泛采用的一種積極的防振措施,其可將振動的振幅降低到?jīng)]有危險的范圍內(nèi)。所以,基礎(chǔ)下壓穩(wěn)定。故僅計算此情況下的T、N值。設(shè)塔腿內(nèi)力為,求彎矩時所算內(nèi)力為,則 對塔腿K型斜材交點求彎矩: 則: 對塔身主材延長線的交點求距。 =避雷線耐張金具總重:= 各種氣象條件下的荷載計算 正常情況Ⅰ(最大風速,V=25m/s)(1)垂直荷載 導線垂直總荷載: 設(shè)計值 地線垂直荷載: 設(shè)計值 塔身重力荷載:(2)水平荷載導地線角度荷載、風荷載標準值: 由已知條件可知: 上導線:h=15+5=20 下導線:h=15 避雷線 h=15+5+= 則導線 :==設(shè)計值 避雷線 設(shè)計值 導線絕緣子串風荷載 設(shè)計值:橫擔風荷載:上橫擔 === =(a=2028mm,b=944mm,h=800mm) 設(shè)計值:kN下橫擔 == = =(a=2315mm,b=1570mm,h=1270mm) 設(shè)計值:塔身風荷載 = = = =(b1=,b2=,h=,) 設(shè)計值:斷線情況下:導線斷線張力: 地線斷線張力: 。); PJ、GJ—— 絕緣子串所受風力及自重力,(N); PJ = nCC—— 絕緣子的受風面積,盤徑為254mm的絕緣子,; A—— 導線截面面積,mm2 ; —— 防震錘的重量,N。所以應(yīng)用絕緣子串的搖擺角校驗是否滿足要求。= 合格。;LV =310桿高的允許弧垂(為非居民區(qū))水平線間距離校驗:(1)水平線間距離 規(guī)程要求的水平線間距離的計算式子為:導線水平距離為合格。 直線塔塔為例。由于以上原因,應(yīng)周密考慮桿塔頭部尺寸的設(shè)計,設(shè)計時主要決定以下電氣方面的要求。同時使線路走廊寬度增大;電磁污染環(huán)境加大。如果桿塔頭部設(shè)計過大,在導線出現(xiàn)不平衡張力(如斷線、不均勻覆冰或脫冰等)時,會增加塔身的扭矩以及對橫擔的彎矩。:由曲線方程:得到 模板的制作 表322根據(jù)以上的條件算出在各檔距下的弧垂K50100150200250300350400由K1制作模板曲線: 塔頭尺寸校驗 桿塔設(shè)計應(yīng)作到安全、經(jīng)濟、美觀。臨界比載法:
