摘　　要：轻型直流输电系统(HVDC Light)作为一种新型的直流输电技术,采用电压源型换流器,功率开关由绝缘栅双极晶体管组成,克服了传统直流输电系统中的一些缺点,具有良好的应用前景。文章在研究了HVDC Light的工作原理和技术特点后,利用EMTDC仿真软件,着重对HVDC Light在短路情况下的电磁暂态过程进行了仿真;同时对轻型直流输电系统的调节能力、控制策略等进行了详细的分析,为进一步研究轻型直流的实验室装置奠定了基础。The HVDC Light system is a new DC transmission technology based on voltage＂ source converters and insulated gate bipolar transistors（IGBT）. It overcomes the flaws of the conventional HVDC system and has a bright application future. In the paper, the operational principle and technical characteristics of the HVDC Light system are introduced, the electromagnetic transient dynamic performance of the system as the short circuit occurs is simulated with the PSCAD/EMTDC software, and the controlling abilities and strategies of the system are analyzed. This study is beneficial to further research on the lab equipment of the HVDC Light system.
