| 摘 要： | 针对电力系统区间低频振荡问题,基于广域测量系统和柔性交流输电系统技术,提出了一种采用时滞广域测量信号的电力系统阻尼控制器设计方法。该方法结合时滞依赖状态反馈鲁棒控制和状态观测理论,实现了广域电力系统的时滞输出反馈鲁棒控制。以四机两区域电力系统为例,设计了晶闸管可控串联补偿(TCSC)附加阻尼控制器。小信号分析和时域仿真结果都表明:所设计的控制器能显著抑制区间低频振荡,并且具有时滞不敏感性和运行条件鲁棒性。

| Abstract: | For inter-area low-frequency oscillation (IALFO) in power system, a novel design strategy for power system damping controller employing time-delay wide-area measurements is proposed based on wide-area measurement system (WAMS) and flexible AC transmission system (FACTS) technology. Combining theories of delay-dependent state-feedback robust control and state observer, time-delay output feedback robust control is realized for wide-area power system. Take four-machine two-area power system as an example, an a... |
