電(dian)(dian)(dian)力(li)增容工程是指通過技術(shu)升級和設(she)(she)備改造，提高電(dian)(dian)(dian)網供電(dian)(dian)(dian)能力(li)以滿足區域用電(dian)(dian)(dian)需求增長(chang)的綜合(he)性工程。隨著經濟(ji)社會快(kuai)速發展，城(cheng)市化進程加快(kuai)以及新(xin)能源大規模接(jie)入(ru)，傳統電(dian)(dian)(dian)網常面臨容量(liang)不足、設(she)(she)備老化等問(wen)題，電(dian)(dian)(dian)力(li)增容成為保(bao)障能源供應(ying)、優(you)化電(dian)(dian)(dian)網結構的重要(yao)手段。

工(gong)程主(zhu)要內容(rong)(rong)包括：一是變(bian)電(dian)(dian)(dian)站擴(kuo)建或新建，通過(guo)增加變(bian)壓(ya)器容(rong)(rong)量、優化(hua)主(zhu)接線(xian)方式提(ti)升電(dian)(dian)(dian)力樞紐的承載(zai)能(neng)力；二是輸(shu)(shu)配電(dian)(dian)(dian)線(xian)路(lu)(lu)改造，采用大截面(mian)導線(xian)、新型桿塔或電(dian)(dian)(dian)纜入地等(deng)方式，提(ti)高線(xian)路(lu)(lu)輸(shu)(shu)送容(rong)(rong)量和(he)可靠性；三是配電(dian)(dian)(dian)設備升級，如更換智能(neng)斷路(lu)(lu)器、加裝無功(gong)補(bu)償裝置等(deng)，增強電(dian)(dian)(dian)網調峰能(neng)力和(he)穩定性。現(xian)(xian)代工(gong)程還(huan)注(zhu)重智能(neng)化(hua)改造，例(li)如部署智能(neng)電(dian)(dian)(dian)表、配電(dian)(dian)(dian)自動化(hua)系統，實現(xian)(xian)遠程監(jian)測和(he)調控(kong)。

實(shi)(shi)施電(dian)力增容需(xu)重(zhong)點把握三個環(huan)節：首(shou)先需(xu)開展(zhan)負(fu)荷預測，結合(he)區域發展(zhan)規劃分析(xi)未來5-10年(nian)的用電(dian)需(xu)求；其(qi)次要嚴格遵循電(dian)網安全標準，合(he)理選擇設備(bei)參數，避免過載或資(zi)源浪費；需(xu)兼顧(gu)環(huan)保要求，優先選用低損耗變壓器(qi)、降噪設備(bei)，并通(tong)過線路(lu)優化減少生態影(ying)響。工(gong)程(cheng)(cheng)實(shi)(shi)施過程(cheng)(cheng)中需(xu)協調多部門，制(zhi)定分階段施工(gong)方(fang)案以降低對用戶的影(ying)響。

電(dian)(dian)(dian)力增容具(ju)有顯(xian)著的社會經濟效(xiao)益：可(ke)有效(xiao)緩解用電(dian)(dian)(dian)高峰期的供電(dian)(dian)(dian)壓力，支撐(cheng)工商業擴產和居民生活品質提(ti)升；促進(jin)光伏、風電(dian)(dian)(dian)等新能源并網消納，助力"雙(shuang)碳"目標實現(xian)；通過電(dian)(dian)(dian)網結(jie)構優化，可(ke)將供電(dian)(dian)(dian)可(ke)靠(kao)性(xing)提(ti)升至99.99%以(yi)上(shang)，降低停電(dian)(dian)(dian)損失。當前我(wo)國年均實施電(dian)(dian)(dian)力增容項(xiang)目超2萬項(xiang)，成為(wei)新型電(dian)(dian)(dian)力系統建設的重(zhong)要支撐(cheng)。
