Optimization Research Of Transmission Lines Design Based On Life Cycle Management Theory

This thesis is based on Qingyun-Jixi 500kV transmission line project on the basis of design optimization. It is mainly research the transmission line project life-cycle management objectives, design optimization methods and innovation of the technical achievements. This is based on the life-cycle management theory design optimization of the transmission line project, and to find the conclusions and disseminate the research results.This research found that the application of the transmission line project life-cycle management theory is focuses on the design phase of the project, such as materials, construction, operation and maintenance and so on, all aspects take into consideration to undertake the comprehensive analysis and optimization, especially in innovation. The implementation of the State Grid Corporation "Friendly-Environment, resources-saving, new technologies, new processes and new materials" design concept will further reflect the life-cycle management concept, saving transmission line construction investment costs.
