地区电网采用高效变压器的节电潜力分析

The energy-saving potential analysis for the adoption of high efficiency transformers in regional power grid

对配电变压器的运行损耗进行了深入的分析,并根据3种变压器损耗算法建立了3种节电潜力评估模型。以广东电网公司某供电局的电网侧和该地区的用户侧配电变压器为例,分析了该地区电网更换低压配电变压器的节电潜力,结果表明,该地区电网低压配电变压器节电潜力巨大,若进行更换,可获得可观的效益。

This paper did deep analysis on the loss of distribution transformers, and set up three energy-saving potential assessment models based on three algorithms for transformer losses ealeulation. Then distrihution transfirmers from a Power Supply Bureau of Guangdong Power Grid Corporation a,ld the regional clients＇ transformers were studied as a case to analyze the energy-saving potential of obsoleting the low-voltage distribution transformers. The results show that there is Large energy-saving potential in distribution transformers of the region. Great economic and soc.ial benefits can he achieved by the replacement of transformers.
