【摘要】：作為堅強智能電網(wǎng)的重要支撐和基礎(chǔ),智能變電站是整個電網(wǎng)建設(shè)的重要組成部分。新一代智能變電站以“系統(tǒng)高度集中、結(jié)構(gòu)布局合理、裝備先進適用、經(jīng)濟節(jié)能環(huán)保、支撐調(diào)控一體”為目標(biāo),可以解決智能變電站安裝復(fù)雜、建設(shè)周期長、運營維護困難、成本高等問題,是未來智能變電站及智能電網(wǎng)發(fā)展的方向。因此,新一代智能變電站的建設(shè)具有非常重要的理論和現(xiàn)實意義。本文對唐山步步川110k V新一代變電站的設(shè)計和應(yīng)用進行了研究。首先完成了需求分析和總體規(guī)劃,給出整體設(shè)計方案及系統(tǒng)方案,在滿足通用設(shè)計規(guī)范、符合新一代智能站要求的基礎(chǔ)上,結(jié)合本地區(qū)運行條件,通過選擇新型智能設(shè)備使變電站整體智能化水平提高。然后設(shè)計了唐山步步川110k V變電站一次系統(tǒng)并進行了設(shè)備選型。結(jié)合設(shè)備發(fā)展的現(xiàn)狀,本工程GIS內(nèi)進出線間隔采用電子式電流電壓組合式互感器;110kV電壓等級及35kV和10kV主變進線間隔采用電子式互感器+智能組件的方式實現(xiàn)一次設(shè)備的智能化。最后設(shè)計了唐山步步川110k V變電站二次系統(tǒng)并進行了智能化二次設(shè)備選型,將站內(nèi)公用、110k V及主變間隔的間隔層設(shè)備布置于II型預(yù)制艙內(nèi),艙內(nèi)設(shè)備采用前接線前顯示裝置,實現(xiàn)了預(yù)制艙式布置的設(shè)計思路。采用預(yù)制光纜技術(shù),實現(xiàn)了一次設(shè)備與二次設(shè)備間光纜、電纜的標(biāo)準(zhǔn)化連接,提高了二次線纜施工的整潔和美觀度,并大大縮短了施工周期。目前該變電站已經(jīng)進入調(diào)試階段,由于依據(jù)國網(wǎng)公司最新智能變電站設(shè)計規(guī)范要求進行設(shè)計,并充分考慮當(dāng)?shù)刈匀画h(huán)境對設(shè)備布置的影響,在滿足智能站設(shè)計要求的基礎(chǔ)上合理布局,節(jié)省了占地,減少了建設(shè)投資。本工程所在地區(qū)為高污穢等級地區(qū),對污染嚴(yán)重地區(qū)有一定的借鑒意義,為新一代智能站的設(shè)計提供了參考,能夠為以后智能變電站的建設(shè)起到示范作用。
[Abstract]:As an important support and foundation of a strong smart grid, smart substation is an important part of the whole power grid construction. The aim of the new generation intelligent substation is "highly centralized system, reasonable structural layout, advanced and applicable equipment, economic, energy saving and environmental protection, support and control", which can solve the complex installation of intelligent substation, long construction period, difficult operation and maintenance, The problem of high cost is the development direction of smart substation and smart grid in the future. Therefore, the construction of new generation intelligent substation has very important theoretical and practical significance. In this paper, the design and application of the new generation substation of 110 kV in Tangshan are studied. First of all, the requirements analysis and overall planning are completed, and the overall design scheme and system scheme are given. On the basis of meeting the general design specifications and the requirements of the new generation intelligent station, combined with the operation conditions of the local area, By selecting new intelligent equipment, the overall intelligence level of substation is improved. Then the system of 110 kV substation in Tangshan step by step was designed and the equipment selection was carried out. Combined with the present situation of equipment development, electronic current voltage combined transformer 110kV voltage grade and 35kV and 10kV main transformer intelligent module are used to realize the intelligence of primary equipment in GIS. Finally, the secondary system of 110kV substation in Tangshan step by step is designed and the intelligent secondary equipment is selected. The interlayer equipment of common 110kV and main transformer interval in the station is arranged in the type II prefabricated cabin. The equipment in the cabin adopts the display device before the front wiring. The design idea of prefabricated cabin layout is realized. By using the technology of prefabricated optical cable, the standard connection of optical cable and cable between primary equipment and secondary equipment is realized, which improves the neatness and beauty of the construction of secondary cable, and greatly shortens the construction period. At present, the substation has entered the commissioning stage. Due to the design requirements of the latest intelligent substation design code of China National Network Company, and fully considering the impact of local natural environment on the equipment layout, On the basis of satisfying the design requirements of intelligent station, the reasonable layout can save the land and reduce the construction investment. The area where the project is located is a high pollution grade area, which has certain reference significance for the seriously polluted area, provides a reference for the design of the new generation intelligent station, and can play an exemplary role in the construction of the intelligent substation in the future.
