Study on Comprehensive Evaluation System of Power Transmission and Transformation Project’s Economy, Operation and Safety Based on TOPSIS with Combined Weight

As a basic industry of national economy, Chinau0027s Power Industry has a direct impact on economic development of society and improvement of peopleu0027s living standard. The construction of power grid project has characteristics of large-scale investment, long-period construction and comprehensive wide-range influence. It is of great significance to deepen research on evaluation system of project’s economy, operation and safety considering basic requirements of safety and stable supply of electric power. This paper establishes a comprehensive evaluation system of power transmission and transformation project’s economy, operation and safety and puts forward a comprehensive evaluation model based on TOPSIS with combined weight. The applicability of this evaluation system and model is validated through project data mining and empirical calculation, providing a theoretical and practical guidance for innovation in theory and method of project evaluation and expansion of power transmission and transformation project evaluation in the future.
