description The invention discloses a leading-phase adaptive power system stabilizer (PSS). The existing PSS models all adopt a multi-stage large phase lead link. On one hand, a multi-stage large phase lead compensation link limits the gain of PSS and severely weakens the oscillation suppression ability of PSS in medium and low bands. On the other hand, for the characteristic of no compensation at different frequencies, there is a need to use a set of same lead parameters to achieve a full-band compensation effect, which has problems in parameter setting and other aspects and is not conductive to field parameter setting in engineering. According to the invention, after active power negative variation and speed variation vectors are synthesized as PSS input, the torque Delta Mpss generated by V(Pe-Omega) through an excitation system is kept close to a speed axis and even overlaps with the speed axis, so as to compensate the hysteresis characteristics under different oscillation frequencies. Meanwhile, ultra-low frequency
