基(ji)本誤差(cha)試驗：電(dian)(dian)壓、電(dian)(dian)流、有(you)功無功

影響(xiang)量(liang)試驗：頻率變化(hua)、諧波(bo)含量(liang)

故障電流誤差試(shi)驗：10倍電流標稱值

短時過量試驗：20倍電流標(biao)稱值

狀態量(liang)試驗：控制輸(shu)(shu)出(chu)、狀態輸(shu)(shu)入、SOE

遙信防抖試(shi)驗：通過設置開出量(liang)輸出脈寬測試(shi)

***檢測(ce)能力：配電(dian)自(zi)動化終(zhong)端測(ce)試儀(yi)可以分成(cheng)各(ge)個***的(de)子(zi)單元(yuan)，各(ge)個子(zi)單元(yuan)應(ying)具有***的(de)功(gong)率(lv)源，并可以***檢測(ce)。

配電自動化終端的建設成效

配電(dian)(dian)自動(dong)化終端安裝(zhuang)以前，一旦(dan)挖玉(yu)沖(chong)線(xian)(xian)(xian)路某處(chu)發生故障(zhang)(zhang)，35千伏(fu)大普(pu)安變電(dian)(dian)站內10千伏(fu)挖玉(yu)沖(chong)線(xian)(xian)(xian)路斷路器就會跳閘，整條線(xian)(xian)(xian)路全部(bu)處(chu)于停電(dian)(dian)狀態(tai)。接到停電(dian)(dian)信息(xi)后(hou)，報修人員只能(neng)(neng)在挖玉(yu)沖(chong)線(xian)(xian)(xian)路52號(hao)桿的斷路器處(chu)，采用(yong)分段試供的方法縮小故障(zhang)(zhang)范圍，然后(hou)進(jin)行分段查找。配電(dian)(dian)自動(dong)化終端建(jian)設(she)提高了10千伏(fu)配電(dian)(dian)線(xian)(xian)(xian)路故障(zhang)(zhang)切除(chu)能(neng)(neng)力，實(shi)現了遠方操作功能(neng)(neng)，增強了配電(dian)(dian)供電(dian)(dian)可靠(kao)性。據悉曲靖供電(dian)(dian)局師(shi)宗縣2018-2019配電(dian)(dian)自動(dong)化終端建(jian)設(she)工程共(gong)涉(she)及師(shi)宗縣9個(ge)鄉鎮（街道），61條10千伏(fu)配電(dian)(dian)線(xian)(xian)(xian)路。計(ji)劃安裝(zhuang)智(zhi)能(neng)(neng)真(zhen)空斷路器142套，架空型故障(zhang)(zhang)指示器73套，電(dian)(dian)纜型故障(zhang)(zhang)指示器5套。截止目前已安裝(zhuang)63臺智(zhi)能(neng)(neng)真(zhen)空斷路器，完成進(jin)度(du)為(wei)44.36%。

配電終端的分布式供電***方法

設在供(gong)電(dian)(dian)(dian)***開始之前已(yi)經(jing)完成故障檢測(ce)和隔(ge)離等過(guo)程(cheng)，且停(ting)電(dian)(dian)(dian)區(qu)域內各處分(fen)(fen)布式電(dian)(dian)(dian)源(yuan)和微(wei)網(wang)已(yi)經(jing)斷(duan)開相應開關，切斷(duan)與主(zhu)(zhu)網(wang)的(de)連接(jie)。本文的(de)分(fen)(fen)布式供(gong)電(dian)(dian)(dian)***主(zhu)(zhu)要分(fen)(fen)為三個(ge)過(guo)程(cheng)，1.搜(sou)(sou)索非故障停(ting)電(dian)(dian)(dian)區(qu)域并尋(xun)找可***電(dian)(dian)(dian)源(yuan)點(dian)(dian);2.以(yi)具備供(gong)電(dian)(dian)(dian)***能(neng)力(li)的(de)聯絡開關為起始點(dian)(dian)，配合網(wang)絡簡(jian)化等值和約(yue)束(shu)條件的(de)計(ji)算，逆向接(jie)力(li)搜(sou)(sou)索確(que)定實際可***供(gong)電(dian)(dian)(dian)區(qu)域;3.以(yi)停(ting)電(dian)(dian)(dian)區(qu)域內的(de)可***孤島運行的(de)分(fen)(fen)布式電(dian)(dian)(dian)源(yuan)處的(de)STU為搜(sou)(sou)索起始點(dian)(dian)，確(que)定大可能(neng)的(de)孤島供(gong)電(dian)(dian)(dian)區(qu)域。
