摘　　要：介绍了在原有高压直流输电 ( HVDC)基础上 ,以电压源换流器和绝缘栅双极晶体管为主要部件发展起来的轻型 HVDC技术 ,分析了轻型 HVDC的基本原理和技术特点 ,比较了轻型 HVDC与传统 HVDC之间的区别 ,简要介绍了轻型 HVDC在国外的一些工程应用以及我国的研究现状 ,并指出目前的主要研究领域 。A kind of new power transmission technology--HVDC light, is introduced in this paper, which is based on the conventional HVDC technology with the voltage source converter (VSC) and insulated gate bipolar transistor (IGBT) as its main components. The basic principle and technology characteristics of HVDC light are summarized, followed by a comparison of HVDC light with conventional HVDC. Some applications of HVDC light abroad and the current development in China are briefly introduced. The main research areas at the present time are pointed out and the application prospects for HVDC light are predicted.
