5月(yue)18日，國家能源集團神東煤炭科技公關項目“基于分(fen)布(bu)式(shi)網絡保護的供(gong)電(dian)(dian)防越(yue)級跳閘關鍵技術的研究與應用”在大柳塔(ta)煤礦順利投入使用近一個月(yue)，成功解決了越(yue)級跳閘的問題，為供(gong)電(dian)(dian)系統(tong)安全可靠運行(xing)提供(gong)了重(zhong)要保障，向智能化供(gong)電(dian)(dian)邁出了堅實的一步。
供(gong)(gong)電(dian)系統(tong)是(shi)煤礦安(an)全生(sheng)產(chan)的(de)(de)基礎保(bao)障(zhang)系統(tong)，其中(zhong)越級跳閘(zha)導致大(da)面積停電(dian)嚴重(zhong)影響礦井安(an)全生(sheng)產(chan)，是(shi)一直困擾礦井供(gong)(gong)電(dian)管理人員的(de)(de)“老大(da)難”問題。4月中(zhong)旬“基于(yu)分布式網絡保(bao)護的(de)(de)供(gong)(gong)電(dian)防越級跳閘(zha)關鍵技術的(de)(de)研究與應用”率先在大(da)柳塔(ta)煤礦大(da)井高壓供(gong)(gong)電(dian)系統(tong)進(jin)行(xing)實踐。數據顯示，該系統(tong)投運前3個(ge)月，越級跳閘(zha)到供(gong)(gong)電(dian)中(zhong)心的(de)(de)地面白(bai)家(jia)渠變(bian)電(dian)所5次，而該系統(tong)投運后至今為(wei)0次。
該技術打破傳統的(de)(de)供電(dian)(dian)(dian)(dian)(dian)故(gu)障(zhang)(zhang)“各自(zi)為政、獨立(li)判(pan)別(bie)(bie)”模式(shi)，以相互間實(shi)時共享的(de)(de)故(gu)障(zhang)(zhang)數據(ju)為判(pan)據(ju)。供電(dian)(dian)(dian)(dian)(dian)上下(xia)級(ji)(ji)自(zi)動(dong)(dong)(dong)識別(bie)(bie)，根據(ju)故(gu)障(zhang)(zhang)位置(zhi)自(zi)動(dong)(dong)(dong)分配上下(xia)級(ji)(ji)開(kai)關(guan)跳閘時間，故(gu)障(zhang)(zhang)定位準，速(su)(su)度(du)快，防越級(ji)(ji)無死角。在有效解決電(dian)(dian)(dian)(dian)(dian)纜短(duan)路故(gu)障(zhang)(zhang)的(de)(de)前提下(xia)，突破了高壓電(dian)(dian)(dian)(dian)(dian)纜接(jie)地(di)精(jing)(jing)確(que)(que)選(xuan)線(xian)(xian)和開(kai)關(guan)執(zhi)行機構(gou)動(dong)(dong)(dong)作時間監(jian)測等(deng)供電(dian)(dian)(dian)(dian)(dian)系(xi)統“瓶頸”問題。通過(guo)輔助選(xuan)線(xian)(xian)信(xin)(xin)號(hao)(hao)源裝置(zhi)主(zhu)動(dong)(dong)(dong)注入(ru)的(de)(de)附件(jian)信(xin)(xin)號(hao)(hao)，以附加信(xin)(xin)號(hao)(hao)為判(pan)據(ju)，以“邊緣(yuan)計算、網絡保護(hu)”防越級(ji)(ji)故(gu)障(zhang)(zhang)定位技術判(pan)別(bie)(bie)接(jie)地(di)點，判(pan)據(ju)清晰、速(su)(su)度(du)快，準確(que)(que)率(lv)高，實(shi)現高壓電(dian)(dian)(dian)(dian)(dian)纜接(jie)地(di)精(jing)(jing)確(que)(que)選(xuan)線(xian)(xian)。開(kai)關(guan)動(dong)(dong)(dong)作機構(gou)動(dong)(dong)(dong)作時間在線(xian)(xian)監(jian)測預(yu)警，徹(che)底解決了越級(ji)(ji)跳閘問題，極大地(di)提高了礦井供電(dian)(dian)(dian)(dian)(dian)系(xi)統自(zi)動(dong)(dong)(dong)化水(shui)(shui)平和安(an)全(quan)管理水(shui)(shui)平，為智能礦山建設提供了供電(dian)(dian)(dian)(dian)(dian)安(an)全(quan)保障(zhang)(zhang)。
