3 電網監控系統相關技術

3.1 分布式智能速斷防越級保護系統(tong)

       系統建設中(zhong)，主要是升級(ji)改造保(bao)護(hu)器(qi)為防越級(ji)保(bao)護(hu)器(qi)，安裝(zhuang)防越級(ji)交換機，搭建光纖縱差(cha)通道(dao)。防越級(ji)保(bao)護(hu)系統組網示(shi)意圖如圖2所示(shi)

3.1.1基本原理(li)

       采用(yong)網(wang)絡化基(ji)因圖譜算法，利用(yong)開關間交(jiao)換故障(zhang)(zhang)信息進行(xing)協商的(de)形式(shi)，判(pan)斷故障(zhang)(zhang)區段，實現全網(wang)零秒速斷，以達到防(fang)越(yue)級跳閘的(de)目的(de)。

3.1.2主要特點和效果

       可(ke)(ke)實現級聯縱差(cha)(cha)保(bao)護(hu)(hu)(hu)、母差(cha)(cha)保(bao)護(hu)(hu)(hu)、三段式(shi)過流、零時(shi)延智能后備保(bao)護(hu)(hu)(hu)。該系(xi)統(tong)保(bao)護(hu)(hu)(hu)分(fen)散，可(ke)(ke)就地安(an)裝(zhuang)，獨立跳閘，符合(he)國家電(dian)網(wang)公司的要求(qiu)。系(xi)統(tong)具有分(fen)布(bu)式(shi)無主(zhu)網(wang)絡結(jie)構(gou)，對通信(xin)依(yi)賴小，故障信(xin)息(xi)協(xie)商(shang)，風險分(fen)散，可(ke)(ke)靠性高。系(xi)統(tong)分(fen)層、分(fen)布(bu)式(shi)光纖網(wang)絡設(she)計，保(bao)護(hu)(hu)(hu)功能就地完成，可(ke)(ke)靠性高。變電(dian)所(suo)間級聯縱差(cha)(cha)保(bao)護(hu)(hu)(hu)可(ke)(ke)避(bi)免站間越級，母線(xian)(xian)故障快速(su)動(dong)作(zuo)差(cha)(cha)動(dong)保(bao)護(hu)(hu)(hu)可(ke)(ke)防(fang)止電(dian)網(wang)擾動(dong)，“T"接線(xian)(xian)差(cha)(cha)動(dong)可(ke)(ke)滿足“一拖多"供電(dian)網(wang)絡，零時(shi)延智能后備保(bao)護(hu)(hu)(hu)可(ke)(ke)消除傳統(tong)后備保(bao)護(hu)(hu)(hu)時(shi)間累積效應的缺點，光纖縱差(cha)(cha)通道實時(shi)監(jian)控、動(dong)作(zuo)行為實時(shi)監(jian)控。

3.2激勵式自(zi)適應漏電(dian)保護系統(tong)

       傳統的(de)漏(lou)電(dian)(dian)(dian)保(bao)(bao)護(hu)方法是以接(jie)(jie)(jie)地電(dian)(dian)(dian)流本身的(de)故(gu)障特征作為故(gu)障判據，由(you)于井下(xia)電(dian)(dian)(dian)網運行方式變化較大(da)，歷次(ci)接(jie)(jie)(jie)地時，接(jie)(jie)(jie)地電(dian)(dian)(dian)流特征都(dou)不(bu)穩定，造成(cheng)了(le)以接(jie)(jie)(jie)地電(dian)(dian)(dian)流特征為判據的(de)漏(lou)電(dian)(dian)(dian)保(bao)(bao)護(hu)經常起不(bu)到作用(yong)，故(gu)采用(yong)激(ji)勵式自(zi)適應漏(lou)電(dian)(dian)(dian)保(bao)(bao)護(hu)系(xi)統。激(ji)勵式自(zi)適應選擇(ze)性漏(lou)電(dian)(dian)(dian)保(bao)(bao)護(hu)系(xi)統由(you)SY3603智能選漏(lou)保(bao)(bao)護(hu)終端、SY3601信號注(zhu)(zhu)入裝置、高(gao)爆(bao)開(kai)關中的(de)ZBT一(yi)11C級(ji)聯縱差綜(zong)合保(bao)(bao)護(hu)器(qi)(qi)構成(cheng)。ZBT．11 C、SY3603安裝在井下(xia)高(gao)壓開(kai)關中，SY3601安裝在地面(mian)10 kV變電(dian)(dian)(dian)所(suo)中，每段母線安裝一(yi)臺(tai)SY3601信號注(zhu)(zhu)入裝置。信號注(zhu)(zhu)人裝置在探測到有接(jie)(jie)(jie)地故(gu)障時，向接(jie)(jie)(jie)地相(xiang)注(zhu)(zhu)入特殊信號(非工頻信號)，經分散(san)安裝的(de)高(gao)開(kai)綜(zong)合保(bao)(bao)護(hu)器(qi)(qi)檢測，信號量值達到設定值時，即判定為線路接(jie)(jie)(jie)地，漏(lou)電(dian)(dian)(dian)保(bao)(bao)護(hu)跳閘。SY3600煤礦電(dian)(dian)(dian)網漏(lou)電(dian)(dian)(dian)保(bao)(bao)護(hu)系(xi)統如圖3所(suo)示

3.3 瞬(shun)時失壓(ya)誤動缺陷的完善

       煤礦井下(xia)電(dian)網在遭(zao)受(shou)雷擊、大(da)負載類設備啟動(dong)(dong)、出口(kou)處短(duan)路(lu)(lu)(lu)等情況時，容易造成(cheng)電(dian)網電(dian)壓(ya)(ya)(ya)(ya)瞬間(jian)波動(dong)(dong)或下(xia)降(jiang)，繼(ji)而(er)無壓(ya)(ya)(ya)(ya)釋(shi)放(fang)線(xian)圈(quan)誤(wu)動(dong)(dong)，引起井下(xia)大(da)面積開(kai)(kai)關(guan)跳閘。為了解決這個問題，為每(mei)臺高壓(ya)(ya)(ya)(ya)防爆開(kai)(kai)關(guan)配置一臺KYD-01瞬時失(shi)壓(ya)(ya)(ya)(ya)智能(neng)(neng)控(kong)(kong)制(zhi)模(mo)塊，保(bao)證交(jiao)流失(shi)壓(ya)(ya)(ya)(ya)情況下(xia)，在0～5 S內維持無壓(ya)(ya)(ya)(ya)釋(shi)放(fang)線(xian)圈(quan)正常工作，母(mu)線(xian)瞬時失(shi)壓(ya)(ya)(ya)(ya)時，高壓(ya)(ya)(ya)(ya)防爆開(kai)(kai)關(guan)不(bu)會誤(wu)動(dong)(dong)跳閘。KYD-01智能(neng)(neng)無壓(ya)(ya)(ya)(ya)釋(shi)放(fang)線(xian)圈(quan)控(kong)(kong)制(zhi)模(mo)塊由開(kai)(kai)關(guan)電(dian)源模(mo)塊、單(dan)片機延時控(kong)(kong)制(zhi)電(dian)路(lu)(lu)(lu)、控(kong)(kong)制(zhi)及告警電(dian)路(lu)(lu)(lu)、智能(neng)(neng)電(dian)容充放(fang)電(dian)回路(lu)(lu)(lu)組成(cheng)，其電(dian)源額定電(dian)壓(ya)(ya)(ya)(ya)為交(jiao)流100 V，源電(dian)壓(ya)(ya)(ya)(ya)波動(dong)(dong)范圍為75％～110％，額定輸出電(dian)壓(ya)(ya)(ya)(ya)24 V，保(bao)持時間(jian)0—5 s可調，級差0．5 S，無壓(ya)(ya)(ya)(ya)時，可輸出常閉接點，供(gong)自動(dong)(dong)化系統報警使用。瞬時失(shi)壓(ya)(ya)(ya)(ya)智能(neng)(neng)控(kong)(kong)制(zhi)模(mo)塊原理如圖(tu)4所示

4 解決對策

       （1）山源KJ360礦用電力監(jian)控(kong)系統與(yu)磐(pan)能(neng)綜合保護(hu)器(qi)配合的(de)問題。由(you)南(nan)京磐(pan)能(neng)公司將分站通訊協議(yi)改為常用的(de)MODBUS通訊協議(yi)，修改后系統運行正常，解決了保護(hu)器(qi)“死機"或(huo)不通信(xin)問題。

       （2）高壓(ya)防爆開關(guan)(guan)(guan)遠(yuan)程(cheng)操作(zuo)拒(ju)動(dong)問題。根據檢(jian)修計(ji)劃(hua)，在(zai)總調度(du)控制室有計(ji)劃(hua)地對井(jing)下所有高壓(ya)防爆開關(guan)(guan)(guan)進(jin)行遠(yuan)程(cheng)分合(he)閘操作(zuo)，發現有6臺(tai)次4臺(tai)高壓(ya)防爆開關(guan)(guan)(guan)出現分合(he)閘拒(ju)動(dong)情(qing)況。經查(cha)，4臺(tai)次拒(ju)動(dong)是開關(guan)(guan)(guan)本身機(ji)構(gou)問題，2臺(tai)次拒(ju)動(dong)是山源監控分站(zhan)與磐能綜合(he)保(bao)護器之間銜接出現問題，通過分析(xi)和檢(jian)查(cha)，解(jie)決(jue)了問題。

       （3）電力(li)監控(kong)系(xi)統不(bu)能(neng)啟(qi)動問題。煤(mei)礦信(xin)息中心機(ji)房2臺電力(li)監控(kong)服(fu)務(wu)器(qi)(qi)監控(kong)系(xi)統出(chu)現(xian)不(bu)能(neng)啟(qi)動問題，顯示數據(ju)庫(ku)連(lian)接異(yi)常，導致整個電力(li)監控(kong)系(xi)統不(bu)能(neng)正常運(yun)行(xing)。將服(fu)務(wu)器(qi)(qi)1 SQL server 2008數據(ju)庫(ku)配(pei)置更改為SQL server和(he)windows混和(he)身份驗(yan)證模(mo)(mo)式，服(fu)務(wu)器(qi)(qi)2重新導人系(xi)統數據(ju)庫(ku)文(wen)件，重新配(pei)置服(fu)務(wu)器(qi)(qi)雙(shuang)機(ji)熱(re)備(bei)。通過(guo)處(chu)理，系(xi)統可正常運(yun)行(xing)，服(fu)務(wu)器(qi)(qi)實現(xian)雙(shuang)機(ji)熱(re)備(bei)模(mo)(mo)式。

       （4）人員培(pei)訓問(wen)(wen)題。針對(dui)運行(xing)階段(duan)出(chu)現的系統(tong)管(guan)理與(yu)操(cao)作人員不(bu)能適應新裝備、工藝的問(wen)(wen)題，新元公司機電(dian)系統(tong)已制(zhi)定(ding)出(chu)培(pei)訓計劃(hua)及修(xiu)改相應制(zhi)度、規程(cheng)，以保證(zheng)電(dian)網(wang)集控系統(tong)能夠穩定(ding)運行(xing)。
