摘要
针对单机无穷大系统，给出了一种电力系统自校正稳定器。它采用基于δ算子的离散模型，在辨识环节中引入活动界限和相对死区，控制器采用滑动极点配置方案。仿真结果显示，在大小干扰的情况下，相对于参数固定的电力系统稳定器，文中所提出的自校正电力系统稳定器抑制低频振荡的能力更强。
A self-tuning power system stabilizer with pole-shifting technology on the basis of -operator is proposed. During paramterindentification, the method imposing movable boundaries and relative dead-zone on identified parameters enhances parameter trackingunder both transient and dynamic conditions. Pole-shifting control is used to increase the flexibility when system operating conditionsvary. Simulation results show that the self-tuning power system stabilizer has better damping characteristics and robustness than theconventional power system stabilizer with fixed-parameter.
