【摘要】：當(dāng)前中國(guó)經(jīng)濟(jì)的迅猛發(fā)展,人們對(duì)于供電質(zhì)量以及不問斷供電的要求與日俱增,發(fā)達(dá)國(guó)家如德國(guó)年平均停電時(shí)間僅有16分鐘,間斷供電時(shí)間僅0.01%。我國(guó)目前供電能力還達(dá)不到這一水平。因此,需要使用切實(shí)可行的配網(wǎng)自動(dòng)化技術(shù)來實(shí)現(xiàn)故障的快速隔離和恢復(fù)供電。同時(shí)國(guó)家電網(wǎng)公司及各地供電公司對(duì)供配電網(wǎng)自動(dòng)化程度也有了新的要求。由此使近年來研究的熱門領(lǐng)域之配電動(dòng)化課題進(jìn)一步升溫,目前配電系統(tǒng)自動(dòng)化的常規(guī)定義是現(xiàn)代計(jì)算機(jī)技術(shù)和現(xiàn)代信息技術(shù)在配電網(wǎng)內(nèi)的實(shí)際應(yīng)用。通過研究實(shí)現(xiàn)配電系統(tǒng)自動(dòng)化的建設(shè)能夠有效提高配電網(wǎng)可靠性和供電質(zhì)量,配合搞好智能化電網(wǎng)建設(shè),進(jìn)一步保障供電與用電雙方的合法利益。本文是作者結(jié)合參與諸暨地區(qū)配電系統(tǒng)自動(dòng)化試點(diǎn)工程建設(shè),對(duì)相關(guān)工作工程技術(shù)問題和工作成果進(jìn)行分析、提煉和總結(jié)后完成的。本文介紹了配電系統(tǒng)自動(dòng)化在諸暨市區(qū)前期研究工作及工程實(shí)際應(yīng)用,分析了配電自動(dòng)化定義、理論意義和主要功能,探討了合理的城市配電網(wǎng)網(wǎng)絡(luò)結(jié)構(gòu)及與之匹配的保護(hù)配置方案,并在此基礎(chǔ)上探討了配電自動(dòng)化實(shí)現(xiàn)的手段及基本功能、配電饋線自動(dòng)化的主要的通信方式和基本原理。之后,對(duì)已確定的諸暨市試點(diǎn)區(qū)域的配電網(wǎng)結(jié)構(gòu)和配電網(wǎng)信息化進(jìn)行核實(shí),并對(duì)配電自動(dòng)化試點(diǎn)的建設(shè)需求進(jìn)行明確。作者提出了試點(diǎn)區(qū)域內(nèi)信息化網(wǎng)絡(luò)全覆蓋、全局管控及分布式想法的配電自動(dòng)化的聯(lián)合模式。根據(jù)各個(gè)不同分站的各種不同的網(wǎng)站結(jié)構(gòu)地域特色,構(gòu)想出采用以智能電網(wǎng)寬帶無線專網(wǎng),太無源光網(wǎng)絡(luò)光纖專網(wǎng)還有電力載波三種不同模式相結(jié)合的通信方案；另外還根據(jù)饋線自動(dòng)化的技術(shù)發(fā)展和諸暨各個(gè)試點(diǎn)地區(qū)的實(shí)況,為實(shí)現(xiàn)配電網(wǎng)自我修復(fù),相對(duì)可靠性比較高的供電區(qū)域以主站集中式饋線自動(dòng)化為主、開關(guān)站就地式饋線自動(dòng)化為輔的方式展開。本文以諸暨地區(qū)當(dāng)前區(qū)域?yàn)榛A(chǔ),設(shè)計(jì)了配電系統(tǒng)自動(dòng)化的改造方案,改設(shè)計(jì)方案通過多名企業(yè)資深工程師、技術(shù)人才的討論研究,并在導(dǎo)師的幫助指導(dǎo)下完成,對(duì)城市的配電自動(dòng)化的建設(shè)與完善提供了一份參考樣本。
[Abstract]:With the rapid development of Chinese economy, the demand for power supply quality and power supply is increasing day by day. In developed countries such as Germany, the average annual blackout time is only 16 minutes, and the discontinuous power supply time is only 0.01 minutes. China's current power supply capacity is not up to this level. Therefore, it is necessary to use feasible automatic distribution network technology to realize fast isolation of faults and restore power supply. At the same time, the State Grid Company and local power supply companies have new requirements for distribution automation. As a result, the topic of distribution dynamics in the hot field of research in recent years has been further heated up. At present, the conventional definition of distribution system automation is the practical application of modern computer technology and modern information technology in distribution network. The construction of distribution system automation can effectively improve the reliability and quality of distribution network, cooperate with the construction of intelligent power network, and further protect the legitimate interests of both power supply and power supply. This paper is based on the author's participation in the construction of Zhuji district distribution system automation pilot project, analyzes the technical problems and results of relevant work engineering, and extracts and summarizes the results. This paper introduces the research work and practical application of distribution system automation in Zhuji urban area, and analyzes the definition, theoretical significance and main functions of distribution automation. This paper discusses the reasonable network structure of urban distribution network and the corresponding protection configuration scheme. On this basis, it discusses the means and basic functions of distribution automation, the main communication mode and basic principle of distribution feeder automation. After that, the distribution network structure and distribution network information of the selected pilot area of Zhuji city are verified, and the construction requirements of distribution automation pilot project are clarified. In this paper, the authors put forward a joint mode of distribution automation with full coverage, global control and distributed idea in the pilot area. According to the different site structure and regional characteristics of different sub-stations, a communication scheme combining three different modes of smart grid broadband wireless private network, too passive optical network and three different modes of power carrier is proposed. In addition, according to the technical development of feeder automation and the actual situation of each pilot area in Zhuji, in order to realize self-repair of distribution network, the main station centralized feeder automation is the main power supply area with relatively high reliability. Switch station local feeder automation auxiliary way to expand. Based on the current area of Zhuji area, this paper designs the transformation scheme of distribution system automation, which is completed through the discussion and research of many senior engineers and technical talents in enterprises, and under the help of the tutor. It provides a reference sample for the construction and perfection of distribution automation in the city.
