[Abstract]:As the basic industry of national economic development, the electric power industry provides a powerful driving force for the development of our economy and society, and to meet the increasing needs of the people. In the face of the increasing demand of social electric power load, the major power enterprises and the State Grid actively carry out large-scale construction and continuously improve the power generation capacity and power transmission and distribution capacity, among which the key link is the construction of transmission and transformation projects. The reasonable transmission and transformation project can ensure that the electric energy can be transported to the load area in the most effective way, at the same time, it can meet the goals of saving the cost, protecting the environment and ensuring the continuous and stable transmission of the electric energy. A scientific comprehensive evaluation of the implementation of power transmission and transformation projects is helpful to measure the overall construction situation of the project and to provide a basis for decision making for the implementation of subsequent projects. Xinghua Xingxi 110 kV transmission and transformation project is built to meet the demands of regional and social electric power load, optimize the power network structure, reduce network loss, improve the quality and reliability of power supply, and finally enhance the efficiency of the national economy. This paper first introduces the research background, significance and related comprehensive evaluation theory of the paper, then introduces the current situation of power system in Xinghua area and the basic situation of the power transmission and transformation project of Xinghua Xingxi 110kV power transmission and transformation project, including the design principles. Scale of construction and application of new technologies; Then according to the present situation and goal of Xinghua power network planning, after considering the construction criteria of project evaluation index system, the evaluation index system of Xinghua Xingxi 110 kV transmission and transformation project is established from three aspects of economy, technology and society. Then, this paper establishes a comprehensive and systematic evaluation model for Xinghua Xingxi transmission and transformation project. Finally, the feasibility of this method is demonstrated by the rational distribution of weights based on entropy weight and the further evaluation and study of this project with TOPSIS method. Xinghua Xingxi 110 kV transmission and transformation project has met the requirements of electric power project construction in terms of technical feasibility, economic feasibility, social feasibility, etc., and according to this paper, we can prove that, The TOPSIS method, which is based on the entropy weight theory to determine the weight, can carry out the comprehensive evaluation of the transmission and transformation engineering effectively, and it lays a certain foundation for the investment decision makers to make the correct decision.
