| The face of our country's energy resources with load centers in the geographical distribution of the actual status of each reverse, building large-capacity, long-distance power transmission network is a necessary way to resolve this contradiction. EHV and UHV power transmission grid as a wide range of important ways, each has an edge, there are also problems. The development of UHV power network in the full set of status and special high-voltage power grid after the planning scheme, in this paper, special high-voltage and EHV transmission system, from the stability, transmission capacity, environmental impact, economy and resource utilization indicators in five areas such as in-depth analysis of, respectively, through the appropriate evaluation method and evaluation model, to carry out techno-economic analysis and comparison. Analysis of selected EHV transmission in Shandong Province and the introduction of special high-voltage transmission technology carried out an empirical analysis, concludes with two kinds of transmission methods used in scientific and rational planning advice and suggestions. |
