【摘要】：为能够深入了解农村低压配电网整体能效情况,在分析配电网节能指标现状的基础上,建立了农村低压配电网能效评价指标体系和综合评价模型。首先,依据相关标准规范,从电网结构、电网设备、电能质量等方面建立了一套适合农村低压配电网能效特点的评价指标体系;然后,确定了单项能效指标的计算方法并提出了基于主成分分析与层次分析法相结合的农村低压配电网能效综合评价模型,该方法克服了单一赋权法的不足,实现了能效指标的客观性与专家定性分析的主观性的有机结合,使评估结果更加合理;最后,通过算例验证了评价方法的有效性和可行性,对今后中国农村低压配电网实施节电改造和节能考核提供参考。
[Abstract]:In order to understand the overall energy efficiency of the rural low-voltage distribution network, based on the analysis of the status quo of the distribution network energy efficiency index, the evaluation index system and comprehensive evaluation model of the rural low-voltage distribution network energy efficiency are established. According to the relevant standards and specifications, a set of evaluation index system suitable for the energy efficiency characteristics of rural low-voltage distribution network is established from the aspects of power network structure, power network equipment, power quality and so on. Then, the calculation method of single energy efficiency index is determined and a comprehensive evaluation model of rural low voltage distribution network energy efficiency based on principal component analysis and analytic hierarchy process is proposed, which overcomes the shortcomings of single weighting method. The objectivity of energy efficiency index is combined with the subjectivity of expert qualitative analysis, which makes the evaluation result more reasonable. Finally, the effectiveness and feasibility of the evaluation method are verified by a numerical example, which provides a reference for the implementation of energy-saving transformation and energy saving assessment in rural low-voltage distribution network in China in the future.
