古(gu)城煤礦供電智(zhi)能(neng)化(hua)提(ti)效能(neng)

穩供電(dian)(dian)(dian)，保安全。吳雷(lei)(lei)雷(lei)(lei)是古(gu)城(cheng)煤(mei)礦(kuang)供電(dian)(dian)(dian)部的(de)主任(ren)科(ke)員，1989年(nian)(nian)出生(sheng)的(de)小伙子(zi)，卻已經是古(gu)城(cheng)煤(mei)礦(kuang)供電(dian)(dian)(dian)系(xi)統(tong)(tong)的(de)“元老”了，從2012年(nian)(nian)古(gu)城(cheng)煤(mei)礦(kuang)建(jian)礦(kuang)籌建(jian)110kV變(bian)電(dian)(dian)(dian)站開始，他(ta)就參與其(qi)中。到2023年(nian)(nian)古(gu)城(cheng)煤(mei)礦(kuang)供電(dian)(dian)(dian)系(xi)統(tong)(tong)的(de)智能化改(gai)造，并新建(jian)鮑店35kV變(bian)電(dian)(dian)(dian)站，他(ta)一(yi)直堅(jian)守(shou)在供電(dian)(dian)(dian)系(xi)統(tong)(tong)一(yi)線(xian)。今年(nian)(nian)的(de)新春走基(ji)層我(wo)們走進(jin)了古(gu)城(cheng)煤(mei)礦(kuang)的(de)供電(dian)(dian)(dian)部，剛(gang)一(yi)進(jin)門(men)，吳雷(lei)(lei)雷(lei)(lei)便指著供電(dian)(dian)(dian)系(xi)統(tong)(tong)的(de)大(da)屏幕興奮(fen)地(di)對記者說：“一(yi)塊屏幕，一(yi)眼(yan)千里，一(yi)鍵遠程操作，這(zhe)是以(yi)前根(gen)本無法想(xiang)象(xiang)的(de)。”

不積小流(liu)，無(wu)以成(cheng)(cheng)江海(hai)。電(dian)流(liu)的(de)(de)(de)微(wei)小粒子在(zai)導線(xian)的(de)(de)(de)世界中奔騰，古城煤礦(kuang)(kuang)供電(dian)系統(tong)的(de)(de)(de)智(zhi)能化改造，讓(rang)節約勞動(dong)成(cheng)(cheng)本(ben)、精準(zhun)高效用電(dian)、供電(dian)安(an)全監管等重要工作(zuo)，變成(cheng)(cheng)了(le)無(wu)數的(de)(de)(de)微(wei)小粒子，在(zai)電(dian)流(liu)的(de)(de)(de)運動(dong)中，讓(rang)電(dian)這種不可或缺的(de)(de)(de)資源，為古城煤礦(kuang)(kuang)安(an)全高效生產賦予了(le)無(wu)窮的(de)(de)(de)力(li)量(liang)。

“井下無人值守”很靠譜

早(zao)上8點，科務(wu)會(hui)召開。匯報完(wan)當(dang)天工作(zuo)(zuo)計劃(hua)安排，吳雷雷又(you)急忙(mang)趕到了110kV變電(dian)站，與地面集控中(zhong)心的(de)值班人員(yuan)例行(xing)溝通。“遠(yuan)程操作(zuo)(zuo)井下開關(guan)，一(yi)切正(zheng)常吧(ba)？”在得到肯定回答后，吳雷雷露出了滿意的(de)笑容(rong)。吳雷雷說，當(dang)前正(zheng)值古城(cheng)煤礦井下變電(dian)所(suo)檢修時期，這個(ge)期間(jian)，每天都需要為井下的(de)各種(zhong)開關(guan)進行(xing)停送(song)電(dian)操作(zuo)(zuo)，事關(guan)檢修人員(yuan)的(de)人身(shen)安全，容(rong)不得半點馬虎。

目(mu)前，在古城煤礦110kV變(bian)(bian)電(dian)站電(dian)力調度中心(xin)，工作(zuo)(zuo)人員(yuan)接到停(ting)電(dian)操(cao)作(zuo)(zuo)指令之后(hou)，只需(xu)要輕點鼠標，在操(cao)控系統內輸入(ru)指令，短(duan)短(duan)數秒，遠(yuan)在百米井下變(bian)(bian)電(dian)所內的開關會自動進行(xing)分(fen)閘、合閘。工作(zuo)(zuo)人員(yuan)只需(xu)要通過攝像(xiang)頭就可(ke)“穩(wen)坐后(hou)方”，清晰掌(zhang)握著設備運行(xing)動態。而在此之前，必須兩(liang)人由專業變(bian)(bian)配電(dian)工趕往(wang)變(bian)(bian)電(dian)所進行(xing)現(xian)場操(cao)作(zuo)(zuo)，光是來往(wang)路程有(you)時候就要2個(ge)小時。

“改造前，我們進行(xing)停送電(dian)操作(zuo)需要手動，必須要經過(guo)唱票、復誦(song)、操作(zuo)、狀態(tai)核(he)對(dui)等人工(gong)步驟，比較(jiao)費(fei)時費(fei)力，現(xian)在(zai)我們可(ke)以在(zai)地面集控(kong)室(shi)通過(guo)電(dian)腦操作(zuo)完成，既安全高效(xiao)又節約人力。”吳雷雷自豪地說。同時，“無人值(zhi)守”也大大減(jian)輕(qing)了(le)運維人員對(dui)設(she)備巡檢的(de)工(gong)作(zuo)量，讓(rang)他們切實地體驗(yan)電(dian)腦前掌控(kong)設(she)備運行(xing)工(gong)況的(de)“千里眼(yan)”“順風耳”感覺。

“實時監控”很安全

“假如，井(jing)下某(mou)一個供電開關(guan)(guan)發生(sheng)了故(gu)(gu)障(zhang)(zhang)，我們可以通過電力監(jian)控系(xi)統，迅速判斷故(gu)(gu)障(zhang)(zhang)線路(lu)(lu)，及時進行處(chu)理，縮短停電時間。”吳雷雷向(xiang)記者介紹說，以前發生(sheng)單相接地故(gu)(gu)障(zhang)(zhang)后，需要(yao)采(cai)用“人(ren)工(gong)拉路(lu)(lu)”的方法確定故(gu)(gu)障(zhang)(zhang)線路(lu)(lu)，此方法存在(zai)很多(duo)弊端，每(mei)一次開關(guan)(guan)的斷開和閉合都會對電網造成沖(chong)擊，減少開關(guan)(guan)使用壽(shou)命(ming)，也會增(zeng)大(da)(da)因操作而帶(dai)來(lai)的事故(gu)(gu)機率，極大(da)(da)降低(di)了供電可靠(kao)性，已經不能滿足生(sheng)產運行需要(yao)。

經過智(zhi)(zhi)(zhi)能(neng)化改造后，當前古城煤礦智(zhi)(zhi)(zhi)能(neng)供(gong)電(dian)系(xi)統(tong)由電(dian)力(li)監(jian)控(kong)系(xi)統(tong)和(he)視頻監(jian)控(kong)系(xi)統(tong)兩部(bu)分組成，能(neng)夠實時(shi)監(jian)測變電(dian)站(zhan)的(de)電(dian)氣(qi)參數，如(ru)電(dian)壓、電(dian)流、功率等，以(yi)及(ji)設(she)備的(de)運(yun)行狀(zhuang)態，如(ru)開關的(de)位(wei)置、斷路(lu)器的(de)狀(zhuang)態等。可以(yi)對收集的(de)數據進行分析和(he)處理(li)，實現對變電(dian)站(zhan)設(she)備的(de)故(gu)障診(zhen)斷。一(yi)旦設(she)備出現故(gu)障或異常，系(xi)統(tong)會(hui)及(ji)時(shi)發出警報(bao)，并提(ti)供(gong)相應的(de)故(gu)障診(zhen)斷和(he)處理(li)建議。另一(yi)方面，布局(ju)的(de)輔助(zhu)設(she)備監(jian)控(kong)系(xi)統(tong)，可實現輔助(zhu)設(she)備數據采集、運(yun)行監(jian)視、操(cao)作控(kong)制、數據存(cun)儲、報(bao)表以(yi)及(ji)智(zhi)(zhi)(zhi)能(neng)控(kong)制管理(li)，為(wei)變電(dian)所綜合(he)監(jian)控(kong)提(ti)供(gong)強(qiang)大的(de)輔助(zhu)信息支撐。

與此同時，監控系統還可以實(shi)時采集各(ge)元件狀態信息(xi)，實(shi)現變電設備狀態全面感知，包括設備運行環境溫度(du)、濕度(du)都可在線24小時監控，自(zi)(zi)動(dong)(dong)啟停開關柜內加熱器除濕等，傳(chuan)統人(ren)工操(cao)作全面轉變為(wei)自(zi)(zi)動(dong)(dong)化操(cao)作，員工操(cao)作更(geng)(geng)安全、更(geng)(geng)高效、更(geng)(geng)便捷(jie)。

“電能分析”很精準

“我們可以(yi)通過電壓波(bo)動曲(qu)線來(lai)分析(xi)，精準(zhun)判斷(duan)故障原因，供(gong)電系統(tong)的電能質量(liang)直接關系到煤礦(kuang)用電安(an)全(quan)和安(an)全(quan)生產。”在(zai)古(gu)城煤礦(kuang)電能質量(liang)監測柜面前，吳雷(lei)雷(lei)談(tan)及電能質量(liang)在(zai)線監測系統(tong)如(ru)數家珍。

在古城(cheng)煤礦(kuang)供(gong)電系(xi)統的末端，井上下的各(ge)種設備(bei)的負荷匯聚于此，任何一點發(fa)生(sheng)短路、單相接地等(deng)(deng)故障，或(huo)(huo)者(zhe)瞬時(shi)大(da)型負載啟動及關閉，都會導致(zhi)的供(gong)電電壓發(fa)生(sheng)暫(zan)態擾動，進而對由礦(kuang)山中變頻器驅動的包(bao)括掘進、綜(zong)采、通風、洗(xi)選等(deng)(deng)裝(zhuang)置產生(sheng)影響，造成停機(ji)或(huo)(huo)者(zhe)故障。

經過智能化改(gai)造，古城煤礦供電(dian)(dian)(dian)(dian)(dian)系統已經具備電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)監(jian)(jian)(jian)測(ce)功能，第一(yi)(yi)部(bu)分是后臺(tai)(tai)監(jian)(jian)(jian)測(ce)系統，負責采(cai)集電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)在(zai)(zai)線(xian)(xian)(xian)監(jian)(jian)(jian)測(ce)裝(zhuang)(zhuang)置(zhi)(zhi)情況，分析設備運行(xing)狀況，每天、每月、每季度、每年(nian)自動(dong)出(chu)具全站(zhan)電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)數(shu)據(ju)報告。第二部(bu)分是電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)在(zai)(zai)線(xian)(xian)(xian)監(jian)(jian)(jian)測(ce)裝(zhuang)(zhuang)置(zhi)(zhi)。在(zai)(zai)副井10kV開(kai)閉(bi)所安(an)裝(zhuang)(zhuang)兩(liang)臺(tai)(tai)電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)在(zai)(zai)線(xian)(xian)(xian)監(jian)(jian)(jian)測(ce)裝(zhuang)(zhuang)置(zhi)(zhi)，用(yong)于(yu)監(jian)(jian)(jian)測(ce)副井10kV開(kai)閉(bi)所Ⅰ、Ⅱ、Ⅲ段(duan)(duan)(duan)母線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)壓、諧波等電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)參(can)數(shu)；在(zai)(zai)桃園(yuan)35kV變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)安(an)裝(zhuang)(zhuang)兩(liang)臺(tai)(tai)電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)在(zai)(zai)線(xian)(xian)(xian)監(jian)(jian)(jian)測(ce)裝(zhuang)(zhuang)置(zhi)(zhi)，用(yong)于(yu)監(jian)(jian)(jian)測(ce)桃園(yuan)35kV變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)35kVⅠ、Ⅱ段(duan)(duan)(duan)母線(xian)(xian)(xian)、10kVⅠ、Ⅱ段(duan)(duan)(duan)母線(xian)(xian)(xian)等電(dian)(dian)(dian)(dian)(dian)能參(can)數(shu)；在(zai)(zai)主(zhu)井35kV變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)安(an)裝(zhuang)(zhuang)兩(liang)臺(tai)(tai)電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)在(zai)(zai)線(xian)(xian)(xian)監(jian)(jian)(jian)測(ce)裝(zhuang)(zhuang)置(zhi)(zhi)，用(yong)于(yu)監(jian)(jian)(jian)測(ce)主(zhu)井35kV變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)35kVⅠ、Ⅱ段(duan)(duan)(duan)母線(xian)(xian)(xian)、10kVⅠ、Ⅱ段(duan)(duan)(duan)母線(xian)(xian)(xian)等電(dian)(dian)(dian)(dian)(dian)能參(can)數(shu)；在(zai)(zai)鮑店35kV變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)安(an)裝(zhuang)(zhuang)兩(liang)臺(tai)(tai)電(dian)(dian)(dian)(dian)(dian)能質量(liang)(liang)(liang)在(zai)(zai)線(xian)(xian)(xian)監(jian)(jian)(jian)測(ce)裝(zhuang)(zhuang)置(zhi)(zhi)，用(yong)于(yu)監(jian)(jian)(jian)測(ce)鮑店35kV變(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)35kVⅠ、Ⅱ段(duan)(duan)(duan)母線(xian)(xian)(xian)、10kVⅠ、Ⅱ段(duan)(duan)(duan)母線(xian)(xian)(xian)等電(dian)(dian)(dian)(dian)(dian)能參(can)數(shu)。這些在(zai)(zai)外行(xing)人(ren)看來(lai)很專業的(de)電(dian)(dian)(dian)(dian)(dian)能參(can)數(shu)，在(zai)(zai)吳雷雷看來(lai)卻(que)像一(yi)(yi)個個音符，彈奏(zou)出(chu)讓他安(an)心、放心的(de)美(mei)妙(miao)樂章。

春節期間，吳雷雷還和平(ping)時一(yi)樣，忙碌而有(you)序。“春節假(jia)期正(zheng)是迎峰度(du)冬的關鍵時期，供(gong)電(dian)(dian)關系著企業安全生產，我們(men)更(geng)(geng)應該(gai)嚴之(zhi)又(you)嚴、慎之(zhi)又(you)慎、細(xi)之(zhi)又(you)細(xi)，確保供(gong)電(dian)(dian)平(ping)穩運(yun)行(xing)。”采訪(fang)結束時，他又(you)像往常一(yi)樣身著防靜電(dian)(dian)服開始進(jin)行(xing)巡查，如今有(you)了“供(gong)電(dian)(dian)智能化”的助力(li)，他們(men)的工作如虎添翼，礦山供(gong)電(dian)(dian)安全也更(geng)(geng)加(jia)保障(zhang)有(you)力(li)。
