Research On The Comprehensive Evaluation Of Path Of Tian Bao 750kV Double Circuit Transmission Line

At present, transmission is the important link of power development. For transmission line engineering, the route problem is the first step in the whole project.. The first step in the design of the route is to make the positioning, that is, the way to set the starting point to the end point.. Transmission lines usually go through many provinces or cities or regions. Transmission line of whether the quality of clearance influence is very extensive, its relationship to power transport engineering safely or not, and whether it is reliable guarantee and so on. To enhance the construction operation to secure coefficient, for engineering economy smoothly is the key is also much attention to things. Therefore in the transmission line engineering design, selection of an optimal transport path to reduce cost, reduce construction time also plays a decisive role, can guarantee the electric power industry is a safe and effective operation. For the stable and healthy development of the whole society to protect the role of. So the transmission line path can not only guide the project path design the optimal, and to supplement and improve the relevant theoretical basis, have a very important guiding significance.This paper mainly focuses on the study of Tianbao 750 KV double circuit transmission line project. Firstly, the research results of a large number of scholars at home and abroad are referred, and the relevant information of the route evaluation is widely collected.. According to the characteristics of Tianbao 750 KV double transmission lines from the five aspects of technical requirements, construction factors, geological, economic factors and environmental benefits, a total of 14 indexes is established with 750 KV double circuit transmission line path evaluation index system, and these indexes are analyzed in detail and discussed, through the analytic hierarchy process method to determine the weights of each index respectively, and fuzzy comprehensive evaluation to evaluate the Tianbao 750 KV double circuit transmission line project, according to the calculation results of fuzzy mathematics and the principle of maximum degree of membership, the project evaluation and description of the project in the technical indicators, has the advantages of construction index, at the same time, the environmental impact of small, and has good economic benefits. Finally, summarizes the main content and the transmission line path model to make forecast expectations, and puts forward some reasonable suggestions, for the implementation of the project management to provide help.
