電力網(wǎng)的發(fā)展對電力系統(tǒng)**通信網(wǎng)提出了更高的要求, 電力通信要求確保電能的生產(chǎn)、輸送、分配、消費在瞬間是同時完成的。為了保證電網(wǎng)安全、經(jīng)濟地運行, 必須配置調(diào)度、保護、遠程控制等系統(tǒng)。這些系統(tǒng)的所有信息傳輸都必須由通信系統(tǒng)提供通道。由此可見, 通信在電力系統(tǒng)中的作用是非常關(guān)鍵的。隨著經(jīng)濟的發(fā)展, 電力系統(tǒng)容量急劇增加, 隨之而來的是輸電超高壓化, 接入業(yè)務(wù)多樣化。 </p> <p> 電力系統(tǒng)一旦發(fā)生故障, 如果通信不暢, 不能及時調(diào)度指揮,就會擴大***范圍, 造成大面積停電甚至系統(tǒng)瓦解,不*經(jīng)濟損失十分慘重, 而且會給社會造成嚴重影響。因此電力系統(tǒng)的通信要有非常高的可靠性。由于SDH技術(shù)具有特有的優(yōu)勢, 采用SDH技術(shù)組網(wǎng)不*適合現(xiàn)代通信發(fā)展的需要,而且特別適合電力系統(tǒng)通信的需要。SDH網(wǎng)是由不同類型的SDH網(wǎng)元設(shè)備, 如終端復(fù)用設(shè)備(TM )、再生器(REG)、分插復(fù)用設(shè)備(ADM )、數(shù)字交叉連接(DXC) 設(shè)備等, 通過光纜互連而成的, 由這些網(wǎng)元設(shè)備完成SDH 網(wǎng)的上下業(yè)務(wù)、交叉連接業(yè)務(wù)、網(wǎng)絡(luò)故障自愈等傳送功能。SDH網(wǎng)的網(wǎng)絡(luò)節(jié)點(網(wǎng)元) 和傳輸線路的幾何排列就構(gòu)成了網(wǎng)絡(luò)的拓撲結(jié)構(gòu)。網(wǎng)絡(luò)的基本拓撲結(jié)構(gòu)大致有這樣幾種方式: 鏈形、星形、樹形、環(huán)形和網(wǎng)格形等。 </p><p> 在各種寬帶光纖接入網(wǎng)技術(shù)中，采用了SDH技術(shù)的接入網(wǎng)系統(tǒng)是應(yīng)用**普遍的。SDH的誕生解決了由于入戶媒質(zhì)的帶寬限制而跟不上骨干網(wǎng)和用戶業(yè)務(wù)需求的發(fā)展,而產(chǎn)生了用戶與**網(wǎng)之間的接入"瓶頸"的問題，同時提高了傳輸網(wǎng)上大量帶寬的利用率。SDH技術(shù)自從90年代引入以來，至今已經(jīng)是一種成熟、標準的技術(shù)，在骨干網(wǎng)中被***采用，且價格越來越低，在接入網(wǎng)中應(yīng)用可以將SDH技術(shù)在**網(wǎng)中的巨大帶寬優(yōu)勢和技術(shù)優(yōu)勢帶入接入網(wǎng)領(lǐng)域，充分利用SDH同步復(fù)用、標準化的光接口、強大的網(wǎng)管能力、靈活網(wǎng)絡(luò)拓撲能力和高可靠性帶來好處，在接入網(wǎng)的建設(shè)發(fā)展中長期受益。

電力系統(tǒng)中基于寬帶數(shù)據(jù)網(wǎng)的應(yīng)用也越來越多, 如圖像監(jiān)控、實時數(shù)據(jù)采集、實時控制、各種管理信息系統(tǒng)(MIS) 等,原先采用窄帶數(shù)據(jù)網(wǎng)承載的業(yè)務(wù)也逐步轉(zhuǎn)移到寬帶數(shù)據(jù)網(wǎng)上。除此之外, 電力通信**網(wǎng)本身還具有一些特點: </p> <p> (1) 電力通信網(wǎng)基本上應(yīng)以光纖通信為主, 以微波通信作備份或補充。 </p> <p> (2) 光纖網(wǎng)絡(luò)拓撲結(jié)構(gòu)復(fù)雜, 整個網(wǎng)絡(luò)節(jié)點數(shù)非常多, 需要傳輸設(shè)備有很強的組網(wǎng)和網(wǎng)絡(luò)管理能力,且對設(shè)備的可靠性要求非常高。 </p> <p> (3) 電力系統(tǒng)所敷設(shè)光纜通常芯數(shù)較少, 考慮到今后可能作為電信運營商, 應(yīng)盡量節(jié)約光纖通信系統(tǒng)所占用的光纖芯數(shù)。 </p> <p> (4) 為滿足整個電力部門目前和將來的所有通信需求, 需要做到話音、視頻和數(shù)據(jù)多網(wǎng)融合。 </p> <p> （5) 目前的業(yè)務(wù)接口需求主要有POTS、2W/4W、E&M、V.24、V.35、ISDN、E1、E3/T 3、10Mb/100Mb以太網(wǎng)接口等, 未來的業(yè)務(wù)需求大,多基于寬帶數(shù)據(jù)網(wǎng)。采用基于SDH 和MSTP, 可使調(diào)度網(wǎng)實現(xiàn)計算機網(wǎng)絡(luò)的遠程互聯(lián), 在SDH平臺上實現(xiàn)以太網(wǎng)業(yè)務(wù)傳送功能, 從而實現(xiàn)二網(wǎng)合一, 且極大地降低網(wǎng)絡(luò)建設(shè)成本。 SDH傳輸網(wǎng)是由不同類型的網(wǎng)元通過光纜線路的連接組成的。云南SDH設(shè)備烽火STM-4</p><p
