一
、什麼是電力網絡通信

所(suo)謂(wei)的(de)電(dian)力(li)網(wang)絡(luo)通(tong)信(xin)主(zhu)要(yao)是(shi)指(zhi)其(qi)承(cheng)載(zai)了(le)與(yu)電(dian)力(li)生(sheng)產(chan)及(ji)高(gao)度(du)相(xiang)關(guan)的(de)業(ye)務(wu)控(kong)製(zhi)機(ji)能(neng)，以(yi)及(ji)與(yu)電(dian)力(li)生(sheng)產(chan)相(xiang)關(guan)聯(lian)的(de)行(xing)政(zheng)業(ye)務(wu)範(fan)圍(wei)。在(zai)電(dian)力(li)網(wang)絡(luo)通(tong)信(xin)技(ji)術(shu)中(zhong)，對(dui)於(yu)不(bu)同(tong)的(de)電(dian)力(li)生(sheng)產(chan)業(ye)務(wu)是(shi)有(you)著(zhe)不(bu)同(tong)的(de)網(wang)絡(luo)參(can)數(shu)控(kong)製(zhi)標(biao)準(zhun)的(de)。電(dian)力(li)網(wang)絡(luo)通(tong)信(xin)係(xi)統(tong)是(shi)由(you)電(dian)源(yuan)
、內部基礎設備、監控終端三個主要部分所組成的。在電力網絡通信係統運行中，電源是支持其正常運行的基礎，因此對電源的安全性、穩定性、耐久性
、高效性等技術性要求是較高的。因為隻有電源不間斷地進行供電，才能保證電力網絡信係統的正常運行安全。

、電力網絡通信常見的故障

電(dian)力(li)網(wang)絡(luo)通(tong)信(xin)係(xi)統(tong)雖(sui)然(ran)隨(sui)著(zhe)時(shi)代(dai)的(de)發(fa)展(zhan)己(ji)經(jing)相(xiang)對(dui)較(jiao)為(wei)完(wan)善(shan)了(le)

，但(dan)是(shi)在(zai)實(shi)際(ji)運(yun)行(xing)中(zhong)，還(hai)是(shi)存(cun)在(zai)著(zhe)一(yi)些(xie)製(zhi)約(yue)性(xing)的(de)問(wen)題(ti)的(de)，這(zhe)主(zhu)要(yao)表(biao)現(xian)為(wei)下(xia)幾(ji)點(dian)：

1)電力網絡通信係統可靠性差

目mu前qian電dian力li網wang絡luo通tong信xin係xi統tong雖sui然ran發fa展zhan的de速su度du相xiang對dui較jiao快kuai，但dan是shi在zai實shi際ji工gong作zuo中zhong卻que普pu遍bian存cun在zai著zhe電dian力li網wang絡luo通tong信xin係xi統tong安an全quan可ke靠kao性xing較jiao差cha的de問wen題ti同tong時shi在zai電dian力li網wang絡luo通tong信xin運yun行xing時shi，對dui數shu據ju信xin息xi資zi源yuan的de共gong享xiang能neng力li還hai存cun在zai著zhe較jiao多duo的de不bu足zu之zhi處chu。如ru果guo在zai電dian力li網wang絡luo通tong信xin係xi統tong運yun行xing中zhong，中zhong心xin係xi統tong或huo是shi某mou一yi站zhan點dian發fa生sheng通tong信xin故gu障zhang時shi，會hui導dao致zhi整zheng體ti電dian力li網wang絡luo通tong信xin係xi統tong處chu於yu癱tan瘓huan狀zhuang態tai中zhong。另ling外wai

2)電力網絡通信傳輸質量差

在(zai)目(mu)前(qian)電(dian)力(li)網(wang)絡(luo)通(tong)信(xin)係(xi)統(tong)中(zhong)，網(wang)線(xian)在(zai)傳(chuan)輸(shu)中(zhong)普(pu)遍(bian)沒(mei)有(you)一(yi)個(ge)較(jiao)好(hao)的(de)屏(ping)蔽(bi)層(ceng)做(zuo)為(wei)支(zhi)撐(cheng)，使(shi)網(wang)絡(luo)通(tong)信(xin)傳(chuan)輸(shu)中(zhong)幹(gan)擾(rao)問(wen)題(ti)無(wu)法(fa)得(de)以(yi)解(jie)決(jue)。另(ling)外(wai)，電(dian)力(li)網(wang)絡(luo)通(tong)信(xin)係(xi)統(tong)中(zhong)所(suo)使(shi)用(yong)的(de)網(wang)絡(luo)多(duo)為(wei)單(dan)股(gu)銅(tong)線(xian)
，在(zai)設(she)備(bei)運(yun)行(xing)中(zhong)銅(tong)線(xian)是(shi)較(jiao)為(wei)容(rong)易(yi)斷(duan)裂(lie)的(de)
，因(yin)此(ci)容(rong)易(yi)出(chu)現(xian)電(dian)力(li)網(wang)絡(luo)通(tong)信(xin)過(guo)程(cheng)中(zhong)網(wang)線(xian)斷(duan)裂(lie)引(yin)起(qi)的(de)網(wang)絡(luo)癱(tan)瘓(huan)問(wen)題(ti)。另(ling)外(wai)，由(you)於(yu)銅(tong)線(xian)的(de)線(xian)徑(jing)較(jiao)細(xi)且(qie)重(zhong)量(liang)較(jiao)輕(qing)
，因(yin)此(ci)在(zai)網(wang)絡(luo)通(tong)信(xin)係(xi)統(tong)運(yun)行(xing)中(zhong)無(wu)法(fa)與(yu)其(qi)它(ta)設(she)備(bei)相(xiang)連(lian)接(jie)，造(zao)成(cheng)了(le)數(shu)據(ju)傳(chuan)輸(shu)的(de)單(dan)一(yi)性(xing)。另(ling)外(wai)
，由(you)於(yu)不(bu)同(tong)區(qu)域(yu)內(nei)對(dui)用(yong)電(dian)量(liang)的(de)要(yao)求(qiu)也(ye)是(shi)不(bu)同(tong)的(de)。因(yin)此(ci)
，sDH節點也就相對較複雜。而就目前來看許多SDH網絡中的連接節點過多
，使電力網絡通信係統自身抗失效能力大大降低，從而嚴重影響了電力網絡通信對數據傳輸的質量安全。

2)電力網絡通信結構複雜

目前國內電力網絡通信管理結構一般都是分為一級、二級、三(san)級(ji)三(san)個(ge)網(wang)絡(luo)通(tong)信(xin)等(deng)級(ji)的(de)，同(tong)時(shi)電(dian)力(li)線(xian)路(lu)的(de)運(yun)行(xing)結(jie)構(gou)也(ye)相(xiang)對(dui)較(jiao)為(wei)複(fu)雜(za)。另(ling)外(wai)
，隨(sui)著(zhe)國(guo)內(nei)各(ge)項(xiang)經(jing)濟(ji)建(jian)設(she)的(de)發(fa)展(zhan)
，促(cu)使(shi)各(ge)中(zhong)小(xiao)型(xing)變(bian)電(dian)站(zhan)也(ye)不(bu)斷(duan)增(zeng)加(jia)
，而(er)各(ge)變(bian)電(dian)站(zhan)內(nei)所(suo)使(shi)用(yong)的(de)sDH節點也就會不斷地串聯接入電力網絡通信係統原有的sDH網絡中，從而使sDHwangluoxingchengjiaoweifuzadejiedianlianjiemoshi。lingwai，suizheshidaifazhandexuqiu，xuduodianliwangluotongxinxitonghaixuyaokuahuanwangshenzhishikuayueduogehuanwangjinxingshujudetongshichuanshu，congerzaochengledianliwangluotongxinxitongwufamanzushujuchuanshuyaoqiuerfashengxitongtanhuanguzhang。

2)建立電力網絡通信導航係統

想有效地防範電力網絡通信故障，建立網絡通信導航係統是十分重要的。首先電力部門要提供全新的電力網絡通信導航係統

、技術谘詢係統以及各係統的操作流程。同時電力部門要存儲大量的網絡通信設備以及網絡性能、canshujishushuju。lingwai，duidianliwangluotongxinxitongjiashezhinenghuagaokejifuwuzhuangzhi。yicilaixiezhudianliwangluotongxingongzuorenyuangengkuaidixunzhaodaowangluotongxinguzhangdesuozaidian，tigaoguzhangdeweixiusudu。lingwai，daohangxitongfuwujishuhaikeyixiezhugongzuorenyuanfaxianbingjiejuedianliwangluotongxinxitongzaiyunxingzhongdebutongguzhangwenti。bujinkeyidadatigaodianliwangluotongxinxitongdeyunxingjineng
