Development Trend And Application Prospect Of National Grid Transmission Technology

The development of China's electric power industry is much faster than that of other countries in the world.Considering the future development of power grid technology,we need to look at the global power grid,research the development trend of international transmission technology,and study the application prospect of advanced transmission technology in China.The healthy development of China's power grid and the safe operation is of great significance.In this thesis,based on the full investigation,the research contents are as follows:First of all,the paper analyzes the typical international grid(including North America Grid,Western Europe Power Grid and Japan Power Grid),including the country's grid structure,the scale of transmission,the development history,problems and solutions,and technology development in the country;Then we summarize the characteristics of the conventional AC transmission technology,the conventional DC transmission technology,the flexible transmission technology and the development actuality,and comb the necessary conditions,advantages and disadvantages which the various transmission technologies are suitable for.Then through the research on the transmission technology applied in some typical international power grid,the adaptability conditions of various transmission technologies are clarified.By comparing the characteristics of the power grid in China,the application prospect of various transmission technologies in China is judged,we propose preliminary proposals to adapt to China's power grid transmission technology development.Finally,based on the above research results,this paper summarizes the innovation and the main work,and prospects for future work.
