摘　　要：随着我国电网的不断发展,HVDC在电力系统中的作用越来越显著。但传统HVDC存在换相失败和在运行中对系统无功需求量大等缺点。新型直流输电作为一种新技术能弥补传统直流输电的部分缺陷,其应用和发展潜力得到了研究人员的广泛关注。为了进一步推动VSC-HVDC在电力系统中的研究和应用,该文从数学模型和控制方式两方面综述了新型直流输电研究的主要成果,总结了其应用研究现状,并对存在问题和进一步研究方向进行了展望。With the rapid development of the power grid, HVDC is becoming more and more important in China. But conventional HVDC has the shortcomings such as the possibility of commutation failure, and the demand of vast amount of reactive power during operation. As a new technology, VSC-HVDC can make up the mentioned weaknesses of conventional HVDC, so it attracts the interests of researchers all around the world. To promote the further study of VSC-HVDC in power system, the main fruits of VSC-HVDC are surveyed in mathematical model and control strategy respectively, its present applications are summerized, and its existing problems and research development are disussed.
