This paper deal with three-loop control system for synchronouns motor, stator current loop, var-current loop, exciter current loop . how to monitoring synchronizing error, and using 80196kc to control exciter 本文討論了三環(huán)控制的同步電動(dòng)機(jī)勵(lì)磁系統(tǒng),即定子電流環(huán),無(wú)功電流環(huán)和勵(lì)磁電流環(huán)。以及同步電動(dòng)機(jī)失步檢測(cè)及以80196kc進(jìn)行控制的方法。
