摘　　要：随着风电在全世界的爆发式发展,大规模风电传输成为研究热点之一。鉴于高压交流和风火打捆特高压直流等输电方案都存在其局限性,更多的传输方案有待研究。提出一种用变功率控制LCC HVDC系统传输大规模陆上风电的方案,即HVDC系统的有功功率实时跟随风功率变化,并基于一个特定案例对该方案进行了全方位的经济和技术可行性研究。为了更好地展现所提出方案的经济性,将定功率控制的LCC HVDC和所提出方案在当前和未来两套价格体系下进行了经济性比较;结果显示,在一定条件下变功率控制HVDC传输方案更具经济竞争力。With the booming development of wind power in the world, its large scale transmission is one of the research focuses. Due to the limitation of two main ways, i. e. HVAC transmission and HVDC transmission combined with thermal and wind power, more transmission solutions should be expected. With concepts introduction, this paper proposes a variable power controlled LCC HVDC system for transmitting on-shore large scale wind power, and based on a specific case, studies both its technical and economic feasi- bilities. To get a better sense of the economic feasibility of the proposed solution, economics between the constant power controlled LCC HVDC and the proposed system are compared under present and future conditions. The results demonstrate that the proposed sys- tem is the better one under certain conditions.
