摘要
电力系统在受到大干扰后,其暂态能量的计算与沿运行轨迹积分的能耗有关.运用能量函数PBES直接法对电力系统暂态稳定性进行分析,可快速、准确地确定系统的临界受扰轨迹,求取电力系统暂态稳定临界故障的切除时间,以更合理、准确地进行继电保护配置、时间整定及系统之间的配合校验.
The calculation of transient energy is related to the integral track when the power system is subjected to a large disturbance. PBES energy could trace the disturbing track of power system coordination between the setting of protective reasonable. function, for the evaluation of transient stability, swiftly and accurately. Meanwhile, it makes the relay and the stability of power system more
