The device detects the rate of power system oscillating center voltage | Ucos φ | with time tto determine whether the power system is oscillating or not , according to which forms the oscillating block of the distance protection .

它利用检测系统振荡时振荡中心电压Ucosψ的时间变率dUcosψ/dt，检测系统是否发生振荡，从而构成距离保护的振荡闭锁。

Application of the algorithm ensures that the result of Ucos φ is accurate , convergent and the true expressions of the voltages and currents in the site of relay when power swing and three-phase short-circuit fault happens at the same time .

用此算法求出的Ucosφ数值精度高，收敛性好，更真实地反映了电力系统振荡过程中发生三相短路时保护安装处电压和电流的变化；
