适应我国大规模风电接入的合理电网结构构建原则的思考

摘要

Focused on fast development of large-scaled wind farm groups in our country, designing principles for reasonable power grid structure are studied in this paper so as to accommodate integration of large-scaled wind farm, and ensure the security and stability of the power system. For the first time,wind farm groups are classified into categories based on the factors related to their integration with the grid. Accordingly,principles of suitable transmission schemes and grid structures are presented for each kind of wind farm group. Several 10 GW super scale wind farm bases planned in China are used as actual cases of the analysis in the paper.%为适应我国风电的快速、大规模发展,从风电合理消纳、提高电网安全性角度,开展大规模风电接入电网的合理电网结构原则研究.首次提出综合考虑风电并网的各项影响因素,将风电基地进行分类；并在此基础上,提出适应各类风电基地接入的合理输电方案及送、受端电网结构构建原则；并以我国规划开发的多个千万千瓦级大型风电基地为实例进行分析.
