| 摘 要： | 为了丰富区间振荡动态特性中同调性指标的获取手段，提出了一种基于改进经验模式分解（R—EMD）技术和相关分析（CA）方法相结合的追踪机电振荡同调性的综合方法。它首先利用R—EMD技术从广域测量系统（WAMS）采集的联络线有功功率、母线电压相角等信号中提取各主导区间模式的分量信号，然后对各通道信号进行时域相关性分析，借助互...

| Abstract: | In order to enrich the acquisition means for the coherence index in the dynamic characteristics of interarea oscillation(IAO),we put forward an integrated algorithm for tracking coherence of electromechanical oscillation using refined empirical mode decomposition(R-EMD) and correlation analysis(CA).Firstly,the components associated with the objective inter-area modes from each tie-line active power signal came from WAMS are extracted by utilizing the R-EMD techniques.Then,the cross-correlation coefficients ... |
