Therefore, the stable operational region of generators is discussed along with the analysis on relationship between under-excitation operation and loss of excitation / synchronism, end temperature rise of stator-core, and automatic excitation regulators etc 針對這種情況,對發(fā)電機(jī)穩(wěn)定運(yùn)行區(qū)域進(jìn)行了探討,并對進(jìn)相運(yùn)行與失磁失步、進(jìn)相運(yùn)行與定子鐵心端部過熱、進(jìn)相運(yùn)行與自動勵磁調(diào)節(jié)器等關(guān)系作了分析。
Though electric system is developing large-scale machine shop in the view of energy saving and reducing waste, small-scale hydraulic power plant and micromidi thermal-electric plant will largely develop because of the national policy of developing small-scale power plant and strengthening environmental protection idea . therefore, the high performance automatic excitation regulator which is applied in small-scale machine shop will have great market potential 雖然目前電力系統(tǒng)從節(jié)能降耗的角度正積極發(fā)展大型機(jī)組、巨型機(jī)組,但從積極發(fā)展小型電站和增強(qiáng)環(huán)保意識的國策上看,今后小水電、中小型熱電廠將大量發(fā)展,因此對高性能的實(shí)用于小型機(jī)組的自動勵磁調(diào)節(jié)器具有巨大的市場潛力。
