The disconnection from power network of power plants under emergency conditions may cause serious frequency drop and then large area outage, even power network collapse.
在突然恶性事故情况下，由于发电厂的退出，电力系统有可能产生严重的频率下降，导致系统崩溃和大面积停电事故。
Underfrequency load shedding (UFLS) is a widely accepted effective measure to repress further frequency drop. Most of UFLS schemes use pre specified steps based on measured frequency to shed load.
低频减载(UFLS)无疑是一种抑制频率下降的有效方法，它依据测量到的频率值，按轮次分步骤地减掉负荷。
