基于层次分析法的现状电网评估方法研究

The research on the evaluation system for existing network based on analytic hierarchy process and Delphi method

现状网评估对电网的建设和改造具有重要的指导意义,现有的方法侧重于对单个项目进行评价,未能形成系统的评价方案。将层次分析法和德尔菲法用于现状电网的评估中,并建立了高、中压现状配电网的评价体系,着重分析和研究同一层次中各指标的权重求解问题。在权重求解的过程中,考虑了多专家形成判断矩阵的差异性,用改进的德尔菲法解决了这一问题。建立的评价体系能比较好地运用到城市电网评估中,具有较好的理论和现实意义。

The evaluation for existing network plays an important guiding part in power grid construction and renovation. But existing methods focus on the evaluation of individual projects and do not form systematic evaluation of the programs. This paper makes use of AHP and Delphi methods for the assessment of network status, and establishes the evaluation grid structure for high-voltage and medium-voltage network. Analysis and research are focused on the same floor of the various indicators for weight problems. During the weight solution process, this paper considers a number of experts formed to judge the different matrixes, and improved Delphi is used to solve the problem. The evaluation system can be better applied in cities＇ network assessment, and has relatively good academic and practical sense.
