| 摘要: |
| 针对联络线可能存在的功率低频振荡，采用广域测量数据并选择合适的反馈信号实现快速的广域时滞阻尼控制。在建立的电力系统线性化模型中考虑广域测量信号时滞，并基于参量Lyapunov理论设计得到了一种新型的广域时滞阻尼控制器，控制器控制律和参数值可以通过参量Lyapunov方程直接得到。基于4机2区仿真模型建立了互联电力系统研究模型，时域仿真表明，所提的广域时滞阻尼控制器能有效地阻尼互联系统区间振荡。 |

| Abstract: |
| As for the potential power oscillation in tie-lines, the wide-area measurement data is employed and the suitable feedback signals are selected to control the wide-area time-delay damping quickly. The linear model of power system is established considering the transmission time delay of the wide-area measurement signals. Meanwhile, a novel wide-area time-delay damping controller is designed, whose control law and parameters can be directly obtained based on parametric Lyapunov function. Moreover, an interconnected electric power system model is established based on the four-generator two-area simulation model. The time-domain simulation shows that the proposed wide-area time-delay damping controller can effectively damp the inter-area oscillations of the interconnected system. |
