基于紧迫度的城中村台区改造优先级评估方法

Priority evaluation method of urban village transformer district reconstruction based on urgency degree

由于城中村台区改造项目繁多,且需要一定的周期和资金,因此需要对改造项目进行合理的优先级排序。在此背景下,提出基于紧迫度分析的城中村台区改造优先级评估方法。首先,结合城中村特点和配电网发展趋势,基于层次分析法建立考虑现状供电能力、负荷增长潜力、源荷调节能力的台区改造紧迫度综合评估指标体系;然后,通过设定指标评分标准、指标权重计算台区改造紧迫度综合评分,量化台区改造紧迫度;最后,根据紧迫度综合评分指导台区改造优先级的排序,根据单项指标评分指导改造措施的选取。以某城中村的6个台区为例,验证了所提出的评估方法具有科学性和实用性,可在工程实际中推广应用。

The district renovation projects for urban and village transformers are various, and those projects also require time and funds. Therefore, a reasonable prioritization of retrofitting projects is required. In this paper, the priority evaluation method of urban village transformer district reconstruction is based on the analysis of urgency degree. Firstly, according to the characteristics of urban village and the development trend of power distribution networks, a comprehensive evaluation index system for comparing the urgency degree of transformer district reconstruction is established by utilizing the analytic hierarchy process. The current power supply capacity, load growth potential, regulating ability of power source and load are considered by the index system. Then, the urgency degree of transformer district reconstruction is quantified through setting the index standard and the index weight to calculate the comprehensive score of transformer district. Finally, the comprehensive score of transformer district is employed to guide the prioritization of transformer district reconstruction. 6 transformer districts of an urban village are simulated, it is proven that the proposed evaluation method is scientific and practical,and can be popularized in engineering practice.
