電力系統(tǒng)通信技術(shù)建設(shè)電力通信網(wǎng)絡(luò)管理系統(tǒng)
摘要:分析了電力系統(tǒng)專用通信網(wǎng)的管理要求,針對(duì)網(wǎng)絡(luò)管理層次多、設(shè)備種類多、網(wǎng)絡(luò)結(jié)構(gòu)復(fù)雜的特點(diǎn),從技術(shù)的角度提出了建設(shè)電力通信網(wǎng)網(wǎng)絡(luò)管理系統(tǒng)的基本要求及解決方案。方案以TMN為基礎(chǔ)兼容其他網(wǎng)管系統(tǒng)標(biāo)準(zhǔn),強(qiáng)調(diào)接口的開(kāi)放性,強(qiáng)調(diào)系統(tǒng)的一體化和獨(dú)立性,強(qiáng)調(diào)網(wǎng)絡(luò)化和對(duì)各種體系結(jié)構(gòu)的兼容性。為網(wǎng)管系統(tǒng)設(shè)計(jì)和方案選擇提供一些有益的建議。

分類號(hào): TM 73 BUILDING TELECOMMUNICATION MANAGEMENT SYSTEM FOR ELECTRIC POWER SYSTEM
Jiao Qun(Nanjing Automation Research Institute, Nanjing 210003, China)
Abstract:This paper analyses the management requirements of telecommunication network for electric power system. According to the characteristics of network management, the main principle of building the telecommunication network management system and the design method are put forward. In the method, the management system is based on TMN system and is compatible with other protocol. The method emphasizes that the system must have unity, independence and open interface, the system should support network and should be compatible with all kind of system structures. The useful advice in designing and selecting management system is offered.Keywords:power systems; telecommunication network; network management system; Q3 protocol adapter; simple network management protocol (SNMP); telecommunication management networks (TMN)▲
引言 近年來(lái)隨著通信技術(shù)的發(fā)展,為了滿足電力系統(tǒng)安全、穩(wěn)定、高效生產(chǎn)的需求及電力企業(yè)運(yùn)營(yíng)走向市場(chǎng)化的需求,電力通信網(wǎng)的發(fā)展十分迅速。許多新的通信設(shè)備、通信系統(tǒng),例如SDH、光纖環(huán)路、數(shù)字程控、ATM等,都紛紛涌入電力通信網(wǎng),使網(wǎng)絡(luò)的面貌日新月異。新設(shè)備的大量涌入表現(xiàn)出通信網(wǎng)的智能化水平不斷提高,功能日益強(qiáng)大,配置、應(yīng)用也十分復(fù)雜。層出不窮的新產(chǎn)品、新功能、新技術(shù)及技術(shù)經(jīng)濟(jì)效益等諸多因素的影響,使可選擇的設(shè)備越來(lái)越多,造成電力通信網(wǎng)中設(shè)備種類的復(fù)雜化。技術(shù)的發(fā)展使某些舊的觀念有了根本的改變,計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)與通信技術(shù)相互交融。傳統(tǒng)通信網(wǎng)絡(luò)的交換、傳輸?shù)阮I(lǐng)域引入了計(jì)算機(jī)網(wǎng)絡(luò)設(shè)備,例如路由器、網(wǎng)絡(luò)交換、ATM設(shè)備等。某些傳統(tǒng)的通信業(yè)務(wù)通過(guò)計(jì)算機(jī)網(wǎng)絡(luò)實(shí)現(xiàn),例如IP電話等。今天通信網(wǎng)與計(jì)算機(jī)網(wǎng)的界限已越來(lái)越模糊。電力通信業(yè)務(wù)已從調(diào)度電話、低速率遠(yuǎn)動(dòng)通道擴(kuò)展到高速、數(shù)字化、大容量的用戶業(yè)務(wù),例如[1] [2] [3] [4] [5] [6] [7]
