DEVELOPMENT AND PROSPECTS FOR HVDC LIGHT

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.
