H^∞电力系统稳定器的设计

DESTGN OF H ∞ POWER SYSTEM STABILIZER

基于Ｈ∞最优控制理论，利用部分极点配置技术，提出了一种电力系统稳定器的设计方法，并给出了非线性仿真结果。与传统的电力系统稳定器相比，文中设计的Ｈ∞ＰＳＳ具有较强的鲁棒性，能够在较大的电力系统运行范围内向系统提供充分的阻尼，抑制振荡，提高了系统的稳定性。

This paper presents a new method of designing power system stabilizer based on H ∞ optimal control theory and partial pole placement technique,The performance of the H ∞ PSS has been evaluated by non linear simulation.It is concluded that such a stabilizer provides better damping to the oscillatory of the system than the conventional PSS under a wide range of operating conditions.
