Through estimating the oscillation (oscillation frequency and damping) observed in a power system, the proposed adaptive PSS can adjust its parameters on line to keep providing suificient damping to the system.

• 这种自适应稳定器通过在线估计系统中发生振荡的频率与阻尼,调整稳定器参数,以保持向系统提供足够的阻尼,从而使其能够适应电力系统运行方式及工况的变化,达到抑制振荡,提高系统稳定性的目的。
