摘要

中低压配电网节能改造的节能潜力巨大，从更换电力设备、采用节能技术以及提升电能质量3个角度，分析并量化了中低压配电网4种节能改造方法的节能效益，建立各节能方法的全寿命周期成本模型，通过净现值、内部收益率及投资回收期对节能方案进行经济效益评估。最后对山东Q 地区的实际算例进行计算，其经济效益评估指标均满足经济可行性，表明本文所建立的模型可为节能方案的经济效益评估提供参考。

Abstract

Considering the huge potential of energy saving in the renovation of medium voltage and low voltage distribution network

the energy saving benefits of four methods are analyzed and quantified from three perspectives

including replacing power equipment

using energy saving technologies and improving power qualities. Then

the life cycle cost model of this project is established and the economic benefit evaluation is carried out through net present value

internal rate of return and dynamic payback period. Finally

a practical example in Shandong Province is calculated. The result shows that it is suitable for investment through these economic indicators

which indicates that the model established in this paper can provide reference for the economic benefit evaluation of the energy saving project.
