【摘要】：节能降损在我国配电网中大有可为。据统计，在各电压等级电网中10kV配电网损耗最高，其降损潜力最大；而配电变压器运行损耗是10kV配电网损耗的主要组成部分，约占配电网总损耗的80%，因此更换配电网中高损耗的变压器是降低配电网网损的主要途径之一。目前，对变压器的节电分析大都局限于更换单台变压器的节电效益，缺少从地区电网的角度对配电变压器节电潜力进行深入的分析，本文针对南方电网现状开展相关研究工作。 降低配电变压器电能损耗的主要途径可以对高能耗变压器进行更新与改造、开发节能变压器。本论文通过对南方电网配电变压器的用能整体情况分析，，收集大量的基础数据，进行如下的分析和研究： a）分析南方电网公司区域内的电网传输损耗特性； b）详细分析非晶合金配电变压器原理、试验及推广应用途径； c）对南方电网公司区域内的配电变压器的节能潜力进行计算分析； d）研究配电变压器传统的TOC技术经济评价方法，提出改进型的配变技术经济评价方法，并通过新装变压器不同容量的选择、改造旧变压器、新装不同型号变压器的选择等具体的例子来证明评价方法的可用性。 本文从地区电网的角度进行了宏观角度的节电潜力分析，相比单台变压器的节能评估，更有宏观层面的指导工作方向的意义。本文最后对上述理论分析与计算方法进行汇总分析，形成具有推广应用价值的相关结论、方法与指导思路。
[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.
