Abstract:Fast cut back (FCB) function can provide start security guarantee for power system in rapid restoration from fault status, quickening units restoration speed. Introduction was made to the FCB working conditions in which thermal power units realized FCB with plant power operation. Simulation was carried out for main electric system operation parameters changes under such working conditions. Via observation on various parameters after FCB taking place, it is proved that thermal units plant can realize units FCB plant with power’s FCB working condition via coordination of each related system and maintain stable operation status in little loss.
Key words: thermal power units; fast cut back; operation parameter
