asynchronous operation

In this paper,a new method of the direction of out-of-step center allocation-function-derivative method is proposed for asynchronous operation based on the equivalent electromotive force at two ends of tie line,the location between oscillation center and center of out-of-step,and their movement characteristics are analyzed.

基于等值两机系统模型,提出一种系统异步运行过程时求取振荡中心新的算法——函数求导法,分析了振荡中心与失步中心的位置以及漂移轨迹的特征,得出联络线两端等值电势幅值不等是产生振荡中心漂移的真正原因,失步解列的依据是失步中心的位置的确定。

Operation cannot be performed while executing asynchronously.

在异步运行时，操作不能被执行。
