| 摘 要： | 特高压直流输电(UHVDC)输电容量大、控制灵活迅速,在我国"西电东送"战略中扮演了重要角色。在传统的直流调制基础上提出了多种信号综合调制的方法,并采用极点配置法整定控制器参数。通过PSCAD/EMTDC软件对锦屏-苏南特高压接入江苏电网进行了仿真研究,结果表明,多信号直流调制能进一步有效提高交流系统的暂态稳定性,取得较好的控制效果。

| Abstract: | The ultra-high voltage DC （UHVDC） transmission, which has great transmission capability and can be controlled flexibly and quickly, plays an important role in the power transmission from western china to the eastern china. Based on the traditional DC modulation methods, a comprehensive modulation method with many kinds of signals is proposed in the paper. Besides, the controller parameters are set by pole assignment. The simulation analysis of Jiangsu power grid with Jinping-Sunan UHVDC integration based on PSCAD/EMTDC is carried on, and the results show that the multi-signal comprehensive DC modulation can further improve the power system transient stability and obtain better control effect. |
