摘　　要：轻型直流输电技术是一种适用于小功率传输的新型直流输电技术 .它采用了绝缘栅极双极型二极管和电压型换流器 ,控制和运行方式简单 ,输出波形好 ,具有广阔的应用范围和良好的发展前景 .文中介绍了轻型直流输电的运行机理 ,分析了它的输入、输出波形和传输功率 ,阐述了其运行特性 ,对其优越性和发展前景进行了讨论 .HVDC Light is a new DC transmission technology for lower power transmission based on the insulated gate bipolar transistors and voltage sourced converters. It can be widely used for its easy and simple control and operation as well as for its good output waveforms. This paper studies the operational mechanisms of HVDC Light, and presents a thorough analysis of its waveforms and the power as well as the operational characteristics. The advantages and development prospects are also pointed out.
