The Research Of Anxin35KV Transmission Lines Optimal Path Selection And Engineering Design

With the development of our national economy and the increasing society energydemand, electric power industry as the country’s main energy industry is facing ahigh-speed developing period. Transmission line as a necessary component of the powersystem plays an important role in the aorta. It’s quality has a critical impact on thesecurity and reliability of electricity transmission work. Therefore how to improve thesecurity, reliability and economy of design, operation and construction received extensiveattention of the whole society. The selection of path for the transmission lines is one ofthe most critical part of the transmission lines planning. Not only does it help to saveengineering costs, short the construction period, but also does it protect the safe of theentire power system operation, and ensure the sustainable development of society.Therefore the path optimization research not only have important guiding significance tothe optimization of transmission lines, but also it enriched the related theory of thetransmission lines route choice and has important theoretical guiding significance.This paper is divided into seven sections. The first part introduces the background、significance of the reaseach, and the main idea for this paper. The second part analyzestransmission line project theory, including grid theory, transmission line engineeringtheory, and transmission line engineering design theory. The third part carries on aresearch to the transmission line path optimization. This part analyzes the transmissionline concepts, meaning, principle, path selection process, as well as influence factors,and then introduces three kinds of path selection method. The fourth part introduces thebasic situation of the new new transmission line project, and lays the foundation for thestudy below. In the fifth part, takes the new transmission line project of Anxin forexample, the fuzzy comprehensive evaluation method is used in route choice. In the sixthpart, summarizes the main conclusion, also look forward to the future of the route choicemodel.
