摘要

在2003年的头几个月，委内瑞拉互联电力系统的峰值负荷比2002年的峰值下降了10%以上。此外，在紧急情况下，被迫以59.9 Hz的稳态频率运行，比标称值低0.1 Hz。因此，有必要对自动弃负荷和区域断开系统的正确性能进行检查

Performance of the Low Frequency Automatic Load Rejection and Area Disconnection Systems of the Venezuelan Interconnected Electric Power System under off-nominal Conditions

During the first months of 2003, the Venezuelan interconnected power system peak load fell more than 10 % below the maximum of 2002. Furthermore emergency conditions forced to operate at 59.9 Hz steady state frequency, 0.1 Hz below its nominal value. Because of this, it was necessary to check the correct performance of the automatic load rejection and area disconnection system
