摘　　要：针对现有配电网后评价方法对投资效果缺乏全面考量,以及投资合理程度研究不够深入的情况,提出了配电网投资效果后评价方法及配电网投资合理性分析方法。首先,从投资建设所产生的运行效果与投资效率两方面,构建了科学、合理、全面的配电网投资效果后评价指标体系;其次,采用主客观结合的评价方法,提出了配电网投资效果后评价体系中指标权重及评价判据的计算方法;最后,利用配电网投资效果后评价体系,提出了投资的整体合理程度判定方法。算例表明,该评估方法能够有效地对配电网进行投资效果后评价,并能找出配电网投资的薄弱环节,对配电网的建设和改造有重要的指导意义。The existing post-evaluation methods of distribution network investment performance lack comprehensive considerations, and the study on the reasonableness of investment is not sophisticated. To tackle the above shortcom- ings, a muhi-attribute comprehensive evaluation method is adopted and a post-evaluation system for investment perfor- mance of distribution network is constructed. Firstly, from the viewpoints of operation effect and investment efficiency related to investment and construction, a scientific, reasonable and comprehensive post-evaluation index system invest- ment for performance of distribution network is built. Secondly, a computation method of index weight and evaluation criterion in the index system is proposed by combining the subjective and objective evaluation methods. Finally, with the proposed post-evaluation system, the reasonableness of the entire investment is analyzed. Results of a numerical example indicate that the method can effectively conduct post-evaluation on the investment performance and determine the weak links of investment. This method is of significance to the construction and transformation of distribution net- work.
