【摘要】：國網(wǎng)發(fā)展策劃部以A+~E類供電區(qū)劃分為基礎(chǔ),在2014年2月發(fā)布了配電網(wǎng)典型供電模式庫,目的是用以指導(dǎo)配電網(wǎng)的統(tǒng)一標準化建設(shè)。伴隨著城鄉(xiāng)經(jīng)濟的不斷發(fā)展,建設(shè)的配電網(wǎng)應(yīng)能滿足經(jīng)濟性和可靠性等目標最優(yōu)的要求。除單獨研究配電網(wǎng)的接線模式和供電模式的技術(shù)指標外,還需考慮模式的動態(tài)建設(shè)問題,即在特定條件下一種模式到另一種模式的過渡。本文主要是對基于配電網(wǎng)典型模式的動態(tài)優(yōu)化建設(shè)展開比較深入的研究。本文研究的是不同供電分區(qū)下典型模式的動態(tài)建設(shè)問題,包括兩個方面的內(nèi)容:一、典型接線模式在不同供電分區(qū)內(nèi)的動態(tài)建設(shè)情況,動態(tài)建設(shè)考慮在初期、發(fā)展期和完善期三個階段內(nèi)的發(fā)展變化,針對不同供電分區(qū)內(nèi)遠景模式的接線形式,通過分析各典型接線模式的特點,總結(jié)出典型接線模式在配電網(wǎng)建設(shè)中的發(fā)展路徑,在此基礎(chǔ)上進一步制定不同分區(qū)內(nèi)接線模式實現(xiàn)過渡的具體路徑,并給出實例。二、典型供電模式在不同供電分區(qū)間的動態(tài)建設(shè)情況,運用經(jīng)濟技術(shù)分析方法對發(fā)展到目標供電模式的動態(tài)建設(shè)方案進行比選,尋找最優(yōu)升級路徑,為配電網(wǎng)供電模式的發(fā)展提供理論基礎(chǔ)。文中提出的水平規(guī)劃年最小費用法相對于“最小單位負荷年費用法”成功避開了負荷密度不斷變化這一復(fù)雜問題,使計算思路更清晰明確。案例分析表明最優(yōu)的動態(tài)建設(shè)路線是逐步升級。
[Abstract]:Based on the division of A / E power supply area, the national power network development planning department released the distribution network typical power supply model library in February 2014, with the aim of guiding the unified standardization construction of distribution network. With the continuous development of urban and rural economy, the construction of distribution network should be able to meet the economic and reliability objectives of the optimal requirements. Besides studying the connection mode of distribution network and the technical index of power supply mode separately, the dynamic construction of the mode should be considered, that is, the transition from one mode to another mode under certain conditions. In this paper, the dynamic optimization construction based on the typical mode of distribution network is studied deeply. This paper studies the dynamic construction of typical modes in different power supply zones, which includes two aspects: first, the dynamic construction of typical connection modes in different power supply zones is considered in the initial stage. The development and change of the three stages in the development period and the perfect period, aiming at the connection form of the prospective mode in different power supply zones, by analyzing the characteristics of each typical connection mode, the development path of the typical connection mode in the distribution network construction is summarized. On the basis of this, the specific paths of different intra-partition wiring modes to realize the transition are worked out, and an example is given. Second, the dynamic construction of the typical power supply mode in different power supply sub-sectors, the use of economic and technical analysis method to develop to the target power supply mode of dynamic construction scheme to compare and select, to find the best way to upgrade. It provides a theoretical basis for the development of distribution network power supply mode. Compared with the "minimum unit load annual cost usage", the horizontal planning annual minimum cost method proposed in this paper successfully avoids the complex problem of the constant change of load density, and makes the calculation thinking clearer and clearer. The case study shows that the optimal dynamic construction route is gradual upgrading.
