| ±660kV DC transmission demonstration project from Ningdong to Shandong is the first DC transmission lines of660kV voltage class all over the world and an important part of building the backbone network of national Grid. This paper analyzes the project comprehensively, including the construction preparation, construction management, economic benefit, social benefit and so on. And then finds out the main post evaluation content of the UHV DC transmission project, also set up the relational post evaluation index system, and make a useful mode with the project, which enhance the comparability between the various projects. It will put forward a series of suggestions to improve the project planning, construction and project management etc, after has a post evaluation from the project implementation process to economics benefit. Through the integrated use of the latest achievements of multi-objective decision making, evaluation management, complex systems theory, power grid construction and planning disciplines, this paper will build up management system and tools to monitor,identify,diagnose, and evaluate the factors affecting the quality of power transmission project investment.The post evaluation theory that has strong theoretical foundation will be applied to the DC transmission project, and has a systematical comprehensive and forward looking research with the project construction process. As the innovation of this paper is to establish the evaluation system of DC transmission project and build the subsequent project planning feedback and organization optimization design. Especially, provides the science evaluation theory support for the construction and building works, like the South Hami to Zhengzhou UHV DC and Luoxidu to the Western Zhe Jiang UHV DC, which will produce positive influence to improve the project investment decision and management level and the power grid investment policies, development planning and the growth of investment income in the future. |
