在风电规模快速增长、规划目标不断提高的发展形势下，为保障风电的合理、有效送出，文章以我国风电发展条件及主要输电方式为基础，开展了风电输送经济性研究。以电价竞争力分析为主要手段，结合风火打捆特高压直流输电技术，分析技术参数的选择及其对输电经济性的影响；通过算例分析，论证了特高压直流输送风电的经济可行性，并提出相关建议。

With the rapid growth and enhanced aim of wind power, large scale development of wind power has become an inevitable trend. To guarantee the reliable and effective transmission of wind power, economic analysis is investigated based on the development conditions and transmission of wind power in our country. The selection of technical parameters and its impact on the economy are analyzed by the means of price competitiveness analysis for UHVDC transmission combined with wind and thermal power. It is shown that the wind power transmitted by UHVDC is economically feasible, and some related suggestions put forward.
