摘　　要：轻型直流输电(HVDC Light)是一种新型的输电技术,以电压源换流器(VSC)为核心,控制上采用脉宽调制技术(PWM)以达到高可控性直流输电的目的。文章首先分析了轻型直流输电系统的基本结构和原理,然后利用MATLAB仿真软件建立一个三电平轻型直流输电系统的仿真模型,最后对仿真结果进行分析,仿真结果表明建立的轻型直流输电系统具有较好的稳定精度和响应速度。文章为将来研究轻型直流输电系统的物理模型奠定了一定的理论基础。HVDC Light is a new technology of DC transmission, in which VSC （ Voltage Source Converter） acted as the core.Control system adopts the PWM technique to reach the high controllable DC transmission.Firstly, the basic structure and fundamental principle of the HVDC Light system were introduced briefly.Then, a simulation model for the typical three-level HVDC Light power transmission system was built on MATLAB.The simulation results were ana-lyzed at last.The simulation results show that the HVDC Light system has good stabilization accuracy and response speed.This study provides a theoretical basis for further research on the physical model of the HVDC Light system.
