摘要
介绍一种新的单片机型自动低频减载装置的切负荷方案——提前预测频率的变化,自适应地修改切负荷级数。该方案具有计算量小、切负荷迅速、准确等特点,从而加速了电网频率的恢复,使频率动态过程大大缩短。仿真计算验证了方案的可行性。
A new load - shedding schem for based - microcomputer UFLS apparatus is proposed.The apparatus modifies the load - shedding grades by predicting frequency change adaptively.The schem features a few computing amount,accuratly and quickly load- shedding,etc.The dynamic frequency process is gready shortten.Simulation results prove the schem feasible.
