【摘要】:電力系統(tǒng)是由發(fā)電廠、輸電線路、變電站、配電線路和用戶計(jì)量等設(shè)備組成的一個(gè)復(fù)雜的發(fā)供用電系統(tǒng)。變電站是電力系統(tǒng)的樞紐,擔(dān)負(fù)著變換電能電壓和分配電能的作用。隨著我國(guó)經(jīng)濟(jì)的快速發(fā)展,各個(gè)地方對(duì)電力的需求也快速增長(zhǎng),特別是在工業(yè)聚集區(qū)、經(jīng)濟(jì)發(fā)達(dá)地區(qū)和人口密集地區(qū)尤其明顯。而對(duì)電力需求大且集中的地區(qū)往往也是經(jīng)濟(jì)發(fā)達(dá)地區(qū),土地資源十分寶貴,很難找到一塊又方又大的能夠建設(shè)傳統(tǒng)變電站的地方,且傳統(tǒng)變電站的建設(shè)周期長(zhǎng),有時(shí)很難滿足這些地區(qū)突然增加的負(fù)荷需求。因此,急需一種能夠快速部署且土地利用率高的新型變電站技術(shù),配送式變電站正是在這種背景下產(chǎn)生的。它靈活的布置方式和快速部署的特點(diǎn)能夠滿足特殊地區(qū)對(duì)電力負(fù)荷的需求。論文首先介紹了配送式110千伏變電站的特點(diǎn)和建設(shè)背景,然后以廣陽(yáng)110千伏變電站為實(shí)例,來(lái)研究討論配送式變電站的設(shè)計(jì)工作。通過(guò)計(jì)算電網(wǎng)潮流和短路電流,確定一次設(shè)備電氣參數(shù)和二次設(shè)備、通信設(shè)備的配置方案;并對(duì)擬定的兩個(gè)站址從水文、地質(zhì)以及交通等情況進(jìn)行調(diào)查分析,經(jīng)過(guò)經(jīng)濟(jì)技術(shù)比較后確定站址位置;最后,根據(jù)前面的分析結(jié)果,進(jìn)行變電站的各部分設(shè)計(jì)工作,并在論文最后進(jìn)行了總結(jié)和展望。
[Abstract]:Power system is a complex power supply and supply system composed of power plants, transmission lines, substations, distribution lines and user metering devices. The substation is the hub of the power system, which is responsible for changing the power and voltage and distribution of power. With the rapid development of China's economy, the demand for electric power has also increased rapidly in various places. Not in the industrial agglomeration area, the economically developed areas and the densely populated areas are particularly obvious. And the areas with large and concentrated power demand are often also economically developed areas, and land resources are very valuable. It is difficult to find a place where traditional substations can be built, and the construction period of traditional substations is long and sometimes difficult to meet. There is a sudden increase in load demand in these areas. Therefore, a new type of substation technology is urgently needed for rapid deployment and high land utilization. The distribution type substation is produced in this context. Its flexible layout and rapid deployment features can meet the demand for power load in special areas. The paper first introduces distribution. The characteristics and construction background of the type 110 thousand volt substation, and then take the Guangyang 110 thousand volt substation as an example to study and discuss the design of the distribution substation. By calculating the power flow and short circuit current of the power grid, the electrical parameters of the equipment and the two equipment and the configuration of the communication equipment are determined, and the proposed two sites are from hydrology and geology. And the traffic and other conditions are investigated and analyzed, the location of the site is determined after the economic and technical comparison. Finally, according to the results of the previous analysis, the design of various parts of the substation is carried out, and the final summary and Prospect of the paper are also carried out.
