Its main role is to connect the power plants and users and offer the user power with a certain voltage and frequency .This design is for a 110KV distribution network planning . The process and method of high voltage distribution network design is introduced briefly in this paper. Its main design elements: In accordance with the load information, the location of the substation to be designed and existing power plants supply situation and make the power balance. Select the conductor according to the economic current density, and verify wire according to mechanical strength, corona, carrying capacity and so on .Calculate the power consumption ,line investment ,substation investment and running costs according to the power distribution of each program. Determine the optimal solution of voltage regulation scheme according to the results of power flow calculation.Key words: high voltage distribution network, wiring scheme,voltage regulation scheme. . . .第一部分 設(shè) 計(jì) 任 務(wù) 書(shū) 高壓配電網(wǎng)的設(shè)計(jì)內(nèi)容(1)根據(jù)地負(fù)荷資料、待設(shè)計(jì)變電所地理位置和已有電廠的供電情況,作出功率平衡。(3)進(jìn)行電網(wǎng)功率分布及電壓計(jì)算,評(píng)定調(diào)壓要求,選定調(diào)壓方案。 設(shè)計(jì)文件及圖紙要求(1)設(shè)計(jì)說(shuō)明書(shū)一份;(2)計(jì)算書(shū);(3)系統(tǒng)接線圖一張。 2)原有發(fā)電廠主接線圖,見(jiàn)圖12及設(shè)備數(shù)據(jù)。表11 待建變電所有關(guān)部資料 編號(hào)最大負(fù)荷 (MW) 功率因數(shù) 二次側(cè)電壓 調(diào)壓要求 負(fù)荷曲線 重要負(fù)荷 (%) A 30 0.9 10 順A 75 B 18 0.9 10 逆B 50 C 32 0.9 10 順
