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.

基于等值兩機系統模型,提出一種系統異步運行過程時求取振蕩中心新的算法——函數求導法,分析了振蕩中心與失步中心的位置以及漂移軌跡的特征,得出聯絡線兩端等值電勢幅值不等是產生振蕩中心漂移的真正原因,失步解列的依據是失步中心的位置的確定。

Operation cannot be performed while executing asynchronously.

在異步運行時，操作不能被執行。
