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(jī)系統(tǒng)模型,提出一種系統(tǒng)異步運(yùn)行過程時(shí)求取振蕩中心新的算法——函數(shù)求導(dǎo)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(lián)絡(luò)線兩端等值電勢(shì)幅值不等是產(chǎn)生振蕩中心漂移的真正原因,失步解列的依據(jù)是失步中心的位置的確定。
Operation cannot be performed while executing asynchronously.
