摘要

本文提出了一种评估机电振荡诱发闪变发生的方法。该方法采用扩展参与因子(EPF)来统计量化分布式同步发电机端电压动态中机电模式的存在。一旦EPF得到的结果表明在分布式发电机的终端电压中机电模式表现的概率很高,就可以对闪变发生的概率进行估计。

An approach to evaluate the occurrence of flicker induced by electromechanical oscillations
In this paper, an approach to evaluate the occurrence of flicker induced by electromechanical oscillations is proposed. This approach employs the extended participation factors (EPF) to statistically quantify the presence of electromechanical modes in the dynamics of the terminal voltage of a distributed synchronous generator. Once the results obtained by the EPF indicate a high probability for the manifestation of the electromechanical mode in the terminal voltage of the distributed generator, an estimate for the probability of occurrence of flicker can be obtained.
