摘要：

Conventional power system stabilizer (PSS) can improve the steady-state stability limit and increase the system positive damping. As known, it has some drawbacks such as the time-consuming tuning and non-optimal damping in the entire operating range. PI adaptive law in simple adaptive control (SAC) can overcome these drawbacks, but it can be only applied to the plants with almost strict positive realness (ASPR) and the computation of adaptive law is really complicated. A new improved SAC based on quadratic performance index was proposed and adopted to PSS design. The simulation results show that this stabilizer possesses good dynamic characteristic and regulation precision. They also show that the proposed PSS can improve the dynamic stability of the power system and suppress the low frequency oscillation.
