一、產品概述

在電(dian)(dian)(dian)(dian)(dian)力(li)系(xi)(xi)統(tong)中(zhong)(zhong)，單相(xiang)(xiang)接(jie)(jie)(jie)(jie)地(di)(di)故(gu)障(zhang)(zhang)(zhang)約占(zhan)全(quan)部故(gu)障(zhang)(zhang)(zhang)的(de)85%,而且(qie)這些(xie)單相(xiang)(xiang)接(jie)(jie)(jie)(jie)地(di)(di)故(gu)障(zhang)(zhang)(zhang)中(zhong)(zhong)，85%以(yi)上是瞬時的(de)和(he)可以(yi)恢復的(de)。電(dian)(dian)(dian)(dian)(dian)力(li)系(xi)(xi)統(tong)運行的(de)安全(quan)性(xing)和(he)供(gong)電(dian)(dian)(dian)(dian)(dian)的(de)可靠性(xing)，在其它條件相(xiang)(xiang)同的(de)情(qing)況下(xia)，取決于(yu)系(xi)(xi)統(tong)中(zhong)(zhong)性(xing)點(dian)的(de)工作方式，即中(zhong)(zhong)性(xing)點(dian)接(jie)(jie)(jie)(jie)地(di)(di)方式。在有效接(jie)(jie)(jie)(jie)地(di)(di)系(xi)(xi)統(tong)中(zhong)(zhong)，單相(xiang)(xiang)接(jie)(jie)(jie)(jie)地(di)(di)故(gu)障(zhang)(zhang)(zhang)線(xian)路會被(bei)迅速切除，防(fang)止(zhi)事故(gu)擴大，這對(dui)(dui)(dui)于(yu)110kV及以(yi)上的(de)輸(shu)變電(dian)(dian)(dian)(dian)(dian)網絡來(lai)說是合適的(de)。35kV及以(yi)下(xia)中(zhong)(zhong)壓輸(shu)配電(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)，由于(yu)對(dui)(dui)(dui)供(gong)電(dian)(dian)(dian)(dian)(dian)可靠性(xing)要求高(gao)，則(ze)采用了中(zhong)(zhong)性(xing)點(dian)非有效接(jie)(jie)(jie)(jie)地(di)(di)方式，或稱(cheng)小電(dian)(dian)(dian)(dian)(dian)流接(jie)(jie)(jie)(jie)地(di)(di)方式，對(dui)(dui)(dui)于(yu)發生幾(ji)率較(jiao)高(gao)的(de)單相(xiang)(xiang)接(jie)(jie)(jie)(jie)地(di)(di)故(gu)障(zhang)(zhang)(zhang)，不會產生危及人身、設備(bei)和(he)系(xi)(xi)統(tong)安全(quan)的(de)短(duan)路電(dian)(dian)(dian)(dian)(dian)流，并具有瞬時性(xing)單相(xiang)(xiang)接(jie)(jie)(jie)(jie)地(di)(di)故(gu)障(zhang)(zhang)(zhang)自(zi)愈能力(li)，系(xi)(xi)統(tong)的(de)線(xian)電(dian)(dian)(dian)(dian)(dian)壓仍(reng)然對(dui)(dui)(dui)稱(cheng)，可以(yi)保(bao)持(chi)對(dui)(dui)(dui)用戶的(de)連續供(gong)電(dian)(dian)(dian)(dian)(dian)。

我國6~35kV中(zhong)壓(ya)(ya)系統主要(yao)采用中(zhong)性(xing)(xing)點不(bu)接(jie)地或經消(xiao)弧線圈接(jie)地的(de)非有效接(jie)地方式，提高(gao)(gao)了(le)中(zhong)壓(ya)(ya)系統的(de)供電(dian)可(ke)靠性(xing)(xing)。但另一方面，這(zhe)種接(jie)地方式也給中(zhong)壓(ya)(ya)輸(shu)配電(dian)系統帶來(lai)了(le)一些(xie)問題，主要(yao)是單(dan)相接(jie)地時(shi)會引起弧光過(guo)電(dian)壓(ya)(ya)及(ji)諧(xie)振過(guo)電(dian)壓(ya)(ya)。特別對于較高(gao)(gao)倍數的(de)間歇性(xing)(xing)弧光接(jie)地過(guo)電(dian)壓(ya)(ya)，如不(bu)能(neng)及(ji)時(shi)消(xiao)除(chu)，可(ke)能(neng)造(zao)成避(bi)雷(lei)器熱崩潰(kui)、電(dian)纜放炮、電(dian)壓(ya)(ya)互感器故(gu)障、絕緣(yuan)閃絡(luo)等各類事(shi)故(gu)，引發第二點接(jie)地造(zao)成危害較大(da)的(de)相間事(shi)故(gu)。

這些事故(gu)(gu)表明(ming)中(zhong)壓系(xi)(xi)(xi)(xi)統中(zhong)性(xing)(xing)(xing)點(dian)(dian)非有(you)效(xiao)接地(di)方式(shi)會(hui)給(gei)系(xi)(xi)(xi)(xi)統電氣設備(bei)的(de)(de)運行安全帶(dai)來(lai)(lai)(lai)一些問(wen)題(ti)(ti)。這些問(wen)題(ti)(ti)如(ru)果不(bu)能有(you)效(xiao)解(jie)(jie)決(jue)，用戶就會(hui)在(zai)(zai)供電可靠性(xing)(xing)(xing)和運行安全性(xing)(xing)(xing)兩者間進行選(xuan)擇，也就是(shi)中(zhong)性(xing)(xing)(xing)點(dian)(dian)接地(di)方式(shi)的(de)(de)選(xuan)擇。多年的(de)(de)運行經(jing)驗表明(ming)，在(zai)(zai)中(zhong)壓系(xi)(xi)(xi)(xi)統選(xuan)擇有(you)效(xiao)接地(di)方式(shi)會(hui)顯著地(di)降低供電可靠性(xing)(xing)(xing)。因此保持中(zhong)性(xing)(xing)(xing)點(dian)(dian)非有(you)效(xiao)接地(di)方式(shi)提高(gao)供電可靠性(xing)(xing)(xing)的(de)(de)優點(dian)(dian)同時解(jie)(jie)決(jue)這種接地(di)方式(shi)帶(dai)來(lai)(lai)(lai)的(de)(de)問(wen)題(ti)(ti)是(shi)近年來(lai)(lai)(lai)中(zhong)壓系(xi)(xi)(xi)(xi)統的(de)(de)一個主要(yao)研究(jiu)課題(ti)(ti)。解(jie)(jie)決(jue)這一問(wen)題(ti)(ti)的(de)(de)關鍵(jian)在(zai)(zai)于準確(que)的(de)(de)故(gu)(gu)障選(xuan)線和有(you)效(xiao)的(de)(de)后續處(chu)理。在(zai)(zai)準確(que)確(que)定故(gu)(gu)障支路(lu)的(de)(de)基礎上(shang)，根據故(gu)(gu)障支路(lu)負載的(de)(de)重要(yao)性(xing)(xing)(xing)以及(ji)故(gu)(gu)障的(de)(de)性(xing)(xing)(xing)質來(lai)(lai)(lai)靈活(huo)、有(you)效(xiao)地(di)確(que)定故(gu)(gu)障的(de)(de)處(chu)理方式(shi)，形成系(xi)(xi)(xi)(xi)統解(jie)(jie)決(jue)方案(an)。

目前市(shi)場上(shang)廣泛使用的(de)(de)小電流(liu)(liu)選線方式(shi)往往受到(dao)接地點阻(zu)抗(kang)變化(hua)范圍大、工況復雜(za)、零序(xu)電流(liu)(liu)信(xin)號弱、電磁(ci)干擾強等各種(zhong)因素的(de)(de)影響，難以(yi)快速(su)、準(zhun)(zhun)確(que)地選出發(fa)生單相接地故障(zhang)支路，選線準(zhun)(zhun)確(que)率較低。

泰隆電(dian)(dian)氣在聯合(he)各界資源力量、在國內外電(dian)(dian)力行業的(de)技術支持(chi)下誕生了一種智能化電(dian)(dian)網(wang)單相接(jie)(jie)地(di)(di)(di)故(gu)障綜合(he)保護管理系(xi)(xi)(xi)統(tong)（簡稱接(jie)(jie)地(di)(di)(di)管理系(xi)(xi)(xi)統(tong)），系(xi)(xi)(xi)統(tong)綜合(he)了直接(jie)(jie)接(jie)(jie)地(di)(di)(di)、不接(jie)(jie)地(di)(di)(di)、電(dian)(dian)阻接(jie)(jie)地(di)(di)(di)、消弧線圈等(deng)接(jie)(jie)地(di)(di)(di)方式(shi)相互配合(he)運(yun)行，比目前電(dian)(dian)力系(xi)(xi)(xi)統(tong)采(cai)用(yong)(yong)單一的(de)中(zhong)性點(dian)不接(jie)(jie)地(di)(di)(di)、消弧線圈接(jie)(jie)地(di)(di)(di)、小（中(zhong)）電(dian)(dian)阻接(jie)(jie)地(di)(di)(di)方式(shi)具(ju)有更高的(de)供電(dian)(dian)可(ke)(ke)靠性、選線準確率高、過電(dian)(dian)壓倍數低和消諧、消弧等(deng)作用(yong)(yong)好(hao)的(de)特點(dian)。新建電(dian)(dian)力系(xi)(xi)(xi)統(tong)可(ke)(ke)以(yi)采(cai)用(yong)(yong)手(shou)動干預(yu)法(fa)運(yun)行，也(ye)可(ke)(ke)以(yi)采(cai)用(yong)(yong)自動模式(shi)運(yun)行。

TE-GMJD單相接(jie)地(di)(di)故障(zhang)綜合(he)管理系統(tong)(tong)整合(he)了(le)(le)中(zhong)性(xing)點非有(you)效接(jie)地(di)(di)系統(tong)(tong)和中(zhong)性(xing)點有(you)效接(jie)地(di)(di)系統(tong)(tong)各自(zi)的(de)(de)優(you)點，既保持(chi)了(le)(le)6~35kV中(zhong)性(xing)點非有(you)效接(jie)地(di)(di)系統(tong)(tong)的(de)(de)供電(dian)可靠性(xing)，又解決了(le)(le)間(jian)歇性(xing)弧光(guang)過(guo)電(dian)壓給系統(tong)(tong)絕緣帶來的(de)(de)安全隱患(huan)。概括(kuo)起來，該裝置有(you)如下(xia)技術特點：

快速準(zhun)確(que)的故障測距定(ding)位(wei)

主控(kong)制(zhi)器采(cai)(cai)用工業計算機嵌(qian)入DSP技術、交流模擬(ni)信(xin)號(hao)數字傳輸技術，當系統(tong)發(fa)生(sheng)單相接(jie)地(di)(di)故(gu)障(zhang)(zhang)時(shi)，主控(kong)制(zhi)器能在20ms時(shi)間內作出響(xiang)(xiang)應，觸發(fa)智能開(kai)關導(dao)通。通過中性點(dian)發(fa)出可控(kong)脈沖電流，瞬(shun)時(shi)放大故(gu)障(zhang)(zhang)點(dian)接(jie)地(di)(di)電流信(xin)號(hao)，該接(jie)地(di)(di)電流可控(kong)，信(xin)號(hao)強，故(gu)障(zhang)(zhang)測(ce)距定位(wei)終端采(cai)(cai)集(ji)器，采(cai)(cai)用高精度傳感器為(wei)(wei)進一步提高故(gu)障(zhang)(zhang)定位(wei)準確率,且智能開(kai)關導(dao)通時(shi)間為(wei)(wei)工頻首半波，采(cai)(cai)用了相位(wei)原理，對(dui)原系統(tong)無影(ying)響(xiang)(xiang)。

故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)測距定(ding)(ding)(ding)位(wei)(wei)(wei)裝置(zhi)(zhi)實(shi)時(shi)采(cai)(cai)集(ji)系統故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)信(xin)(xin)(xin)號(hao)，應用(yong)多種(zhong)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)（根據(ju)(ju)(ju)用(yong)電實(shi)際情況）方法(fa)(fa)進行綜合故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)，具體(ti)包括：殘流增量法(fa)(fa)及有功功率數(shu)(shu)字(zi)傳輸法(fa)(fa)、信(xin)(xin)(xin)號(hao)注入。裝置(zhi)(zhi)通過粗糙集(ji)理(li)論(lun)確定(ding)(ding)(ding)各(ge)種(zhong)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)方法(fa)(fa)的(de)有效域，根據(ju)(ju)(ju)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)信(xin)(xin)(xin)號(hao)特(te)征(zheng)自(zi)動(dong)對(dui)每一種(zhong)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)方法(fa)(fa)得出(chu)的(de)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)結(jie)果進行可信(xin)(xin)(xin)度量化評估，應用(yong)證(zheng)據(ju)(ju)(ju)理(li)論(lun)將多種(zhong)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)方法(fa)(fa)融合到一起，最大限度地保證(zheng)各(ge)種(zhong)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)方法(fa)(fa)之間(jian)實(shi)現(xian)優勢互補。為了(le)避免(mian)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)信(xin)(xin)(xin)號(hao)受到干擾而導致誤判，裝置(zhi)(zhi)采(cai)(cai)用(yong)了(le)連(lian)續故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)方法(fa)(fa)，每隔(ge)一定(ding)(ding)(ding)時(shi)間(jian)(1秒)重新(xin)采(cai)(cai)集(ji)數(shu)(shu)據(ju)(ju)(ju)進行分(fen)析，只要(yao)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)沒有消失，裝置(zhi)(zhi)的(de)故(gu)(gu)(gu)(gu)(gu)障(zhang)(zhang)定(ding)(ding)(ding)位(wei)(wei)(wei)計算就不停(ting)止。

裝置具有故(gu)(gu)障錄波(bo)(bo)(bo)功能，可以提供(gong)故(gu)(gu)障前(qian)后的波(bo)(bo)(bo)形，包括故(gu)(gu)障發生前(qian)的一個周(zhou)期和故(gu)(gu)障發生后五(wu)個周(zhou)期的波(bo)(bo)(bo)形。可保存現場(chang)故(gu)(gu)障錄波(bo)(bo)(bo)數據和選線(xian)結果20000次。

裝置具備(bei)跳(tiao)閘功能，大容(rong)量觸(chu)點可(ke)以(yi)直接接入跳(tiao)閘回路(lu)，實現(xian)故障定(ding)位后的故障切除(chu)。也可(ke)與自動重(zhong)合閘結合，實現(xian)故障定(ding)位后的自動弧光(guang)處理和進(jin)一步確認。具體根據(ju)用電企業的實際情(qing)況進(jin)行方案設(she)計(ji)。
有效的故(gu)障(zhang)處理

根據單相(xiang)(xiang)接(jie)地(di)故障的性(xing)質及負載的重要程度(du)，再(zai)采用(yong)不(bu)同的工(gong)作方(fang)式，讓消弧(hu)線圈和觸(chu)點消弧(hu)、電(dian)阻接(jie)地(di)、不(bu)接(jie)地(di)互(hu)相(xiang)(xiang)配合，互(hu)相(xiang)(xiang)保護，有效消除弧(hu)光過電(dian)壓(ya)，解決(jue)單相(xiang)(xiang)接(jie)地(di)故障。具體根據用(yong)電(dian)企業(ye)的實際情況(kuang)進行方(fang)案設計。

在系統正常運行(xing)及發(fa)生故障(zhang)時(shi)，可(ke)對系統的(de)過(guo)電(dian)(dian)壓(ya)(ya)、低電(dian)(dian)壓(ya)(ya)、PT斷(duan)線、諧(xie)(xie)振、單相接地(di)電(dian)(dian)壓(ya)(ya)及其(qi)諧(xie)(xie)波、電(dian)(dian)壓(ya)(ya)閃變、弧光(guang)過(guo)電(dian)(dian)壓(ya)(ya)、雷(lei)擊過(guo)電(dian)(dian)壓(ya)(ya)、操作(zuo)過(guo)電(dian)(dian)壓(ya)(ya)等穩態(tai)、暫態(tai)沖(chong)擊進行(xing)實時(shi)監(jian)測、定時(shi)記(ji)錄、報(bao)警，供(gong)用戶分析系統的(de)工作(zuo)狀(zhuang)態(tai)及判(pan)斷(duan)故障(zhang)原因(yin)。
