    摘 要:依据北方某城市”煤改电”工程实施现状,从经济效益、社会效益和配电网运行状况等方面,提出了用于评估“煤改电”工程综合效益的评价指标体系;采用层次分析法和熵权法相结合的组合赋权法,对指标体系进行赋权,弥补了单项赋权法的不足。根据工程实际数据及信息进行单项指标计算,采用组合赋权法确定的权重进行综合效益评估。通过实际算例对某地区的不同“煤改电”工程项目进行了综合效益评估和对比,并分析了其低分指标的产生原因,提出了改进措施,对“煤改电”工程项目的进一步推广有
借鉴与指导作用。

    Abstract: According to the present situation of "coal-to-electricity" projects in a northern city, the evaluation index system was put forward to estimate the comprehensive benefits of the projects with the aspects of the economic benefit, the social benefit and the operation condition of a distribution network. The index system was empowered by the combination of weighting method of analytic hierarchy process and entropy weighting method, which overcame the shortcomings of single weighting method. After the calculation of the single index on the basis of the actual data and information, the comprehensive benefit evaluation can be carried out with the weight determined by the combination weighting method. An actual example was applied for the comprehensive benefit evaluation and comparison to different "coal-toelectricity" projects. The causes of the low score index were analyzed and the improvement measures were put forward, which can give the reference and the guidance for the further popularization application and implementation of the projects.
    Key words: "coal-to-electricity" project; benefit evaluation; combination weighting method; analytic hierarchy process method; entropy weighting method
