摘要

A power system stabilizer (PSS) to bring the constant in a phase lead-lag circuit of the PSS to an optimum value by having such procedures carried out in its phase lead-lag compensation circuit as to apply the rule to lead the phase of the PSS when the period of the power fluctuation in each mode tends to decrease and to lag the phase of the PSS when conversely the period tends to increase by means of a fuzzy inference device to detected results of the periods weighted by the degrees of the tendency, to superpose the outputs obtained by application of the rule to obtain the center of gravity, and therewith finally to vary the constant in the amplification and phase lead-lag circuit of the PSS.
