Study on Main Connection Line and Main Circuit Parameters of ±1100kV UHVDC
Construction of ±1100kV UHVDC transmission channels from West to East in China is conducive to promote large scale optimal allocation of energy sources. In UHVDC transmission systems, main DC equipment development, project implementation, reliability level and power loss caused by converter outage are deeply impacted by main connection line of converter and main circuit parameters. This is also the most important step of project system research. Firstly, evaluation method of converter connection line of UHVDC projects are proposed in this paper. Secondly, according to previous project construction, equipment design and manufacturing experiences, three converter connection schemes are proposed and main circuit parameters are analyzed respectively based on each connection scheme. Finally, a proposed assessment method of converter main connection line is used to determine a reasonable and effective main connection topology for Changji-Guquan ±1100kV UHVDC project.
