Urban electric grid overall evaluation system established based on layer analysis and Delphi

The utility model discloses a present city power network comprehensive evaluation system based on analytical hierarchy process and Delphi method. The system classifies and layers the characters of the city power network and then forms an integrated system including a plurality of layers according to the relationships and the differences between the characters of the city power network. The endmost character of the system is first evaluated, and then calculation is performed one layer after another according to definite calculation methods, finally a comprehensive and integrated evaluation of the city power network is obtained. The higher the comprehensive score, the better the whole situation of the city power network; namely, the construction technology rationality, the operation safety, the power supply quality and the operation economy of the power network all reach to a high level.
