An evaluation index system and comprehensive evaluation model on high-voltage distribution network planning

High-voltage(110 kV/35 kV) distribution network plays an important role in the development of city power grid. The paper focuses on its planning evaluation index system and comprehensive evaluation model. An evaluation index system applicable to high-voltage distribution network planning is established, which includes some new indices, such as Substation(Line) Capacity Coordination, Old Equipment Proportion, Annual Investment Balance, etc. Analytic hierarchy process based on Delphi method is proposed to set index weight. Judgment matrix is used in grading index. According to the evaluation index system and comprehensive evaluation model, a final evaluation result will be promoted layer by layer. The evaluation index system and comprehensive evaluation model are verified to be scientific and reasonable in a local high-voltage distribution network.
