【摘要】：配電自動(dòng)化通信網(wǎng)的設(shè)計(jì)在配電自動(dòng)化系統(tǒng)中起著至關(guān)重要的作用。遠(yuǎn)方數(shù)據(jù)采集、遠(yuǎn)方控制、故障定位與隔離、負(fù)荷轉(zhuǎn)移等功能的實(shí)現(xiàn)都依賴于終端設(shè)備和主站之間的通信系統(tǒng),可以說(shuō)通信系統(tǒng)質(zhì)量直接決定配電自動(dòng)化系統(tǒng)性能的優(yōu)劣,然而通信模式多種多樣,每種模式的存在都有其各自適用范圍,可能某種模式在某一系統(tǒng)中應(yīng)用良好,但在其他系統(tǒng)中卻不能正常工作。因此,針對(duì)不同情況制定出一套合理的通信系統(tǒng)尤為重要。實(shí)際工作中情況多變,必須要把基礎(chǔ)理論和具體實(shí)際情況結(jié)合考慮,從經(jīng)濟(jì)性、可靠性、建設(shè)難易程度多方面綜合考量,選出最適合當(dāng)前系統(tǒng)的通信模式。論文主要工作如下:1.分析了不同通信方式的性能,主要從有線通信方式和無(wú)線通信方式兩方面展開(kāi)分析,總結(jié)了不同通信方式的優(yōu)點(diǎn)和缺點(diǎn):光纖成本越來(lái)越低,運(yùn)用的場(chǎng)所也越來(lái)越多。DLC技術(shù)衰耗大,仍處于試驗(yàn)研究階段。數(shù)傳電臺(tái)在負(fù)荷控制系統(tǒng)以及城市照明系統(tǒng)中得到廣泛應(yīng)用。擴(kuò)頻通信基于電力線,抗干擾強(qiáng),前景良好。2.深入研究了光纖通信方案,對(duì)光纖通信方式的特點(diǎn)、功能、以及實(shí)施方案做了具體規(guī)劃。在設(shè)計(jì)通信模式時(shí)應(yīng)用了GPRS技術(shù),對(duì)GPRS技術(shù)進(jìn)行了詳細(xì)的介紹,它可應(yīng)用于遠(yuǎn)程、數(shù)據(jù)量較小、數(shù)據(jù)接收發(fā)出頻率高的配電自動(dòng)化系統(tǒng),并提出了利用GPRS技術(shù)實(shí)現(xiàn)的通信方式。3.根據(jù)以上相關(guān)技術(shù)的研究,結(jié)合泰州供電公司的實(shí)際情況,分析了當(dāng)前存在的問(wèn)題和不足,對(duì)泰州供電公司的配電自動(dòng)化通信方式從功能劃分、通信分層、通信網(wǎng)結(jié)構(gòu)、通信介質(zhì)、實(shí)施方案幾個(gè)方面進(jìn)行合理設(shè)計(jì)。并結(jié)合自身工作經(jīng)歷,詳細(xì)介紹了泰州域配用電通信網(wǎng)改造工程。4.在泰州市區(qū)完成配電自動(dòng)化和通信網(wǎng)絡(luò)的全覆蓋,實(shí)現(xiàn)“三遙/二遙”、配電SCADA、饋線自動(dòng)化、配電運(yùn)行管理等功能,逐步提高調(diào)度員的遠(yuǎn)方控制能力,采用信息交換總線實(shí)現(xiàn)與相關(guān)系統(tǒng)的互聯(lián),充分發(fā)揮各項(xiàng)功能在調(diào)度管理中的應(yīng)用。未來(lái)增加電網(wǎng)分析應(yīng)用功能,以配電拓?fù)涞姆治鰬?yīng)用和實(shí)用功能為基礎(chǔ),滿足故障情況時(shí)系統(tǒng)快速自愈,有效提高區(qū)域內(nèi)供電可靠性。
[Abstract]:The design of distribution automation communication network plays an important role in distribution automation system. The realization of remote data acquisition, remote control, fault location and isolation, load transfer and other functions all depend on the communication system between terminal equipment and main station. It can be said that the quality of communication system directly determines the performance of distribution automation system. However, there are a variety of communication modes, each mode has its own scope of application, one mode may be well used in one system, but it can not work properly in other systems. Therefore, it is very important to develop a reasonable communication system according to different situations. The situation in practice is changeable, so we must combine the basic theory with the actual situation, and choose the most suitable communication mode for the current system from the aspects of economy, reliability and construction difficulty. The main work of this paper is as follows: 1. This paper analyzes the performance of different communication modes, mainly from the aspects of wired communication mode and wireless communication mode, and summarizes the advantages and disadvantages of different communication modes: the cost of optical fiber is getting lower and lower. More and more sites are used. DLC technology is still in the stage of experimental study. Data transmission station is widely used in load control system and city lighting system. Spread spectrum communication based on power line, strong anti-interference, good prospects. 2. In this paper, the scheme of optical fiber communication is deeply studied, and the characteristics, functions and implementation of the mode of optical fiber communication are planned. GPRS technology is applied in the design of communication mode, and GPRS technology is introduced in detail. It can be used in distribution automation system with remote, small data volume and high data receiving and sending frequency, and a communication mode .3. realized by GPRS technology is put forward. According to the above related technology research, combined with the actual situation of Taizhou Power supply Company, the existing problems and shortcomings are analyzed. The communication mode of distribution automation of Taizhou Power supply Company is divided into functions, communication layers and communication network structure. Communication medium, the implementation of several aspects of reasonable design. And combined with their own work experience, the Taizhou area distribution power communication network transformation project. 4. Complete distribution automation and communication network coverage in Taizhou urban area, realize the functions of "three remote / second remote", distribution SCADA, feeder automation, distribution operation management, etc., and gradually improve the dispatcher's remote control ability. The information exchange bus is used to realize the interconnection with related systems, and the application of all functions in dispatching management is brought into full play. In the future, the power network analysis and application functions will be added, based on the analysis, application and practical functions of the distribution topology, the system will be able to heal itself quickly in case of failure, and effectively improve the reliability of power supply in the area.
