摘要
快速甩负荷(FCB)功能能够为电力系统迅速恢复故障状态提供启动安全保障,加快机组的恢复速度。介绍了火电机组实现甩负荷带厂用电运行的FCB工况,并对此工况下主要电气系统运行参数的变化进行仿真,通过观察FCB发生后各参数变化,证明火电厂通过各相关系统的配合能够成功实现机组甩负荷带厂用电的FCB工况,并在较小损耗下维持稳定运行状态。
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.
