【摘要】：節(jié)能降損在我國配電網(wǎng)中大有可為。據(jù)統(tǒng)計，在各電壓等級電網(wǎng)中10kV配電網(wǎng)損耗最高，其降損潛力最大；而配電變壓器運行損耗是10kV配電網(wǎng)損耗的主要組成部分，約占配電網(wǎng)總損耗的80%，因此更換配電網(wǎng)中高損耗的變壓器是降低配電網(wǎng)網(wǎng)損的主要途徑之一。目前，對變壓器的節(jié)電分析大都局限于更換單臺變壓器的節(jié)電效益，缺少從地區(qū)電網(wǎng)的角度對配電變壓器節(jié)電潛力進行深入的分析，本文針對南方電網(wǎng)現(xiàn)狀開展相關(guān)研究工作。 降低配電變壓器電能損耗的主要途徑可以對高能耗變壓器進行更新與改造、開發(fā)節(jié)能變壓器。本論文通過對南方電網(wǎng)配電變壓器的用能整體情況分析，，收集大量的基礎(chǔ)數(shù)據(jù)，進行如下的分析和研究： a）分析南方電網(wǎng)公司區(qū)域內(nèi)的電網(wǎng)傳輸損耗特性； b）詳細分析非晶合金配電變壓器原理、試驗及推廣應(yīng)用途徑； c）對南方電網(wǎng)公司區(qū)域內(nèi)的配電變壓器的節(jié)能潛力進行計算分析； d）研究配電變壓器傳統(tǒng)的TOC技術(shù)經(jīng)濟評價方法，提出改進型的配變技術(shù)經(jīng)濟評價方法，并通過新裝變壓器不同容量的選擇、改造舊變壓器、新裝不同型號變壓器的選擇等具體的例子來證明評價方法的可用性。 本文從地區(qū)電網(wǎng)的角度進行了宏觀角度的節(jié)電潛力分析，相比單臺變壓器的節(jié)能評估，更有宏觀層面的指導(dǎo)工作方向的意義。本文最后對上述理論分析與計算方法進行匯總分析，形成具有推廣應(yīng)用價值的相關(guān)結(jié)論、方法與指導(dǎo)思路。
[Abstract]:Energy saving and loss reduction are promising in China's distribution network. According to statistics, the loss of 10kV distribution network is the highest, and the potential of loss reduction is the greatest. Distribution transformer operation loss is the main component of 10kV distribution network loss, accounting for about 80% of the total loss of distribution network, so replacing the transformer with high loss in distribution network is one of the main ways to reduce the distribution network loss. At present, the power saving analysis of transformers is mostly limited to the power saving benefit of replacing a single transformer, and the power saving potential of distribution transformers is not thoroughly analyzed from the point of view of regional power grid. This paper carries out relevant research work in view of the current situation of Southern Power Grid. The main way to reduce the power loss of the distribution transformer is to renew and transform the high energy consumption transformer and develop the energy saving transformer. Based on the analysis of the energy consumption of the distribution transformer in Southern Power Grid, this paper collects a large number of basic data, and analyzes and studies the transmission loss characteristics of the power grid in the area of Southern Power Grid Company based on the following analysis and research: a). B) analyzing the principle of amorphous alloy distribution transformer in detail, testing and popularizing the way to calculate and analyze the energy saving potential of distribution transformer in the area of China Southern Power Grid Corporation by; c); D) study the traditional TOC technology and economic evaluation method of distribution transformer, put forward the improved distribution transformer technical and economic evaluation method, and transform the old transformer through the choice of different capacity of the new transformer, The selection of new types of transformers and other specific examples to prove the usability of the evaluation method. In this paper, the power saving potential of the regional power grid is analyzed from a macro perspective. Compared with the energy saving evaluation of a single transformer, it is of great significance to guide the direction of work at the macro level. At the end of this paper, the theoretical analysis and calculation methods mentioned above are summarized and analyzed, and the relevant conclusions, methods and guiding ideas are formed.
