| 摘 要： | 对轻型直流输电运行原理和技术特点、控制模式以及控制系统进行简要的介绍和分析,根据我国电网的特点,对其在我国电网中的应用作了初步探讨.采用电磁暂态仿真程序(PSCAD/EMTDC)对轻型直流输电系统在区域互联、多馈入直流输电系统中的应用进行了建模仿真,结果表明轻型直流输电在提高所并联交流线路的暂态稳定性、抑制区域间联络线的功率振荡等方面能起到积极作用,其电压、有功、无功的快速调节能力可为多馈入直流输电系统提供良好的电压支撑,有利于相联的传统直流输电系统故障后的快速恢复.

| Abstract: | After brief introduction and analysis to technique characteristics, the control modes and control system of HVDC light, a discussion about applying HVDC light to China power grid was presented. Models of applying HVDC light to AC/DC hybrid system and Multi-Infeed Direct Current system were built by PSCAD/EMTDC. The simulation results show that HVDC light can improve effectively the transient stability of the AC/DC hybrid system and the MIDC system due to its contribution to supporting voltage, damping of the power oscillations. |
