【摘要】：變電站是電力系統(tǒng)的一個重要組成部分,它的安全穩(wěn)定的運行與社會經(jīng)濟的發(fā)展密不可分。因此,對變電站選址的有關問題進行研究具有重要的意義。在目前的電網(wǎng)規(guī)劃中,選擇新建變電站地址是一項的重要環(huán)節(jié),選址的合理性直接影響到未來電網(wǎng)的構(gòu)架,關系著電力輸送的可靠性及經(jīng)濟性。近些年來,人們逐步認識到了新建變電站的布局規(guī)劃,對城市發(fā)展規(guī)劃的重要性,新建變電站的站址確定和線路走廊的選擇被納入城市規(guī)劃,為電網(wǎng)發(fā)展提供所必需的戰(zhàn)略土地資源,由此看出,變電站選址就顯得非常重要。開展對新建變電站的選址必須要考慮到是否靠近負荷中心等多種因素,科學合理地選定新建變電站的位置和供電范圍,可以有效地避免電力系統(tǒng)跨區(qū)域交叉供電情況,從而提高電力系統(tǒng)運行的效率。當前對新建變電站選址的方法有很多種,每種方法有各自的優(yōu)點和不足。本文首先介紹了選題背景和變電站選址的目的、原則和程序,對國內(nèi)外研究現(xiàn)狀進行了分析,對變電站選址評價指標進行了概述。然后詳細闡述了了灰色系統(tǒng)理論的基本原理、體系構(gòu)成及灰.色關聯(lián)分析法,最后以河南省范縣龍王莊鄉(xiāng)110千伏變電站的選址為例,通過對比應用常規(guī)的選址方法與基于灰色理論的選址方法,得出了站址選擇一致性的結(jié)論,論證出了基于灰色理論的變電站選址是一個有效的方法。目前該變電站建設項目的初步設計已獲省電力公司批準,并進入具體的設計、施工階段。本文解決了110千伏龍王莊選址中的諸多實際問題,對變電站選址具有一定的指導意義。
[Abstract]:Substation is an important part of power system, and its safe and stable operation is closely related to the development of social economy. Therefore, it is of great significance to study the problems related to substation location. Selection of new substation address is an important link, the rationality of location directly affects the structure of the future power grid, and relates to the reliability and economy of power transmission. In recent years, people have gradually realized the layout planning of new substation. The importance of urban development planning, the location determination of new substations and the selection of line corridors are incorporated into urban planning, which provides the necessary strategic land resources for the development of power grid. It is very important to select the location of the new substation. In order to select the location and the power supply range of the new substation scientifically and reasonably, the location of the new substation must be taken into account whether it is close to the load center or not. It can effectively avoid cross-region cross-supply of power system and improve the efficiency of power system operation. Each method has its own advantages and disadvantages. Firstly, this paper introduces the background of the selected topic and the purpose, principles and procedures of the substation location, and analyzes the current research situation at home and abroad. The evaluation index of substation location is summarized. Then the basic principle of grey system theory, system composition and grey color correlation analysis are described in detail. Finally, the location of 110 kV substation in Longwangzhuang Township, Fan County, Henan Province is taken as an example. By comparing the conventional site selection method with the grey theory based site selection method, the conclusion of the consistency of site selection is obtained. It is proved that the substation location based on grey theory is an effective method. At present, the preliminary design of the substation construction project has been approved by the provincial power company and entered the concrete design. In the construction stage, this paper solves many practical problems in the location of 110 kV Longwangzhuang, which is of certain guiding significance to the location of substation.
