农村电网改造中若干技术经济问题的研究

摘要

我国投入几千亿元进行城市电网和农村电网的改造，这是一项跨世纪工程。将这大量的资金如何科学而合理地运用到电网的改造和建设中，是当今政府及电力企业十分关注的热点问题。针对农村电网改造以节电效益最大为目标，着重分析了导线的经济截面选择，0.4 kV供电半径及配电变压器的布点方式等几个主要问题，并同时针对农村电网改造和建设提出了一些看法与大家共同商榷。%City and rural electric network modification, in which hundreds of billion RMB Yuan was invested in our country, was a key project to be carried out across the century. How to make scientific and rational use of the large funds in electric network modification, was a hot issue that government and electric power enterprises paid close attention to. Because the major objective of rural electric network modification was to gain the benefit of saving electric power, this paper centered on analysing wire economic section, 0.4 kV power supply radius and layout mode of transformers distribution.
