摘 要:快速甩負荷(FCB)功能能夠為電力系統迅速恢復故障狀態提供啟動安全保障,加快機組的恢復速度。介紹了火電機組實現甩負荷帶廠用電運行的FCB工況,并對此工況下主要電氣系統運行參數的變化進行仿真,通過觀察FCB發生后各參數變化,證明火電廠通過各相關系統的配合能夠成功實現機組甩負荷帶廠用電的FCB工況,并在較小損耗下維持穩定運行狀態。
關鍵詞:火電機組;快速甩負荷;運行參數

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
