Design features of Three Gorges-Changzhou ±500 kV HVDC project

in this paper, design results of Three Gorges-Changzhou HVDC Project were summarized. The major features of this project were introduced. In specifying performance requirements, the special features of this project, conditions and requirements of both side AC systems as well as environment conditions and requirements were considered carefully. The most up to date technology of HVDC and computerized controls were followed. Efforts have been paid to promote development of HVDC technology and to minimize the cost of the project with the basis of ensuring security and stability of the AC/DC systems.
