Conventional power system stabilizer ( cpss ) has such shortcoming as complex design , fussy parameter testing , poor adaptability and so on . in this article formula fuzzy control algorithm is put into the design of pss . quantified factors and modifying factors , which have large effect on the performance of formula fpss , are optimized 本文針對(duì)傳統(tǒng)電力系統(tǒng)穩(wěn)定器( cpss )設(shè)計(jì)復(fù)雜、參數(shù)調(diào)試繁瑣、適應(yīng)性差等缺點(diǎn),將一種公式型模糊控制算法應(yīng)用于pss設(shè)計(jì),并對(duì)公式型模糊電力系統(tǒng)穩(wěn)定器的性能影響較大的量化因子和修正因子進(jìn)行優(yōu)化,從而設(shè)計(jì)出一種自尋優(yōu)模糊電力系統(tǒng)穩(wěn)定器( sofpss ) 。
