| 摘 要： | 为了提高区间振荡动态特性中振型信息的有效获取速度,提出了一种利用相关分析的快速估计区间振荡振型的新方法.它首先通过一个由先验知识设计并在线校正的低通或带通滤波器,从电力系统广域测量系统(wide area measurement system,WAMS)采集的各联络线有功功率信号中提取以弱阻尼模式为主导的分最信号,然后...

| Abstract: | In order to improve the effective acquisition speed for mode shape information in the dynamic characteristics of inter-area oscillation,we put forward a new algorithm for rapid estimating the inter-area oscillation mode shapes and corresponding modes using correlation analysis.Firstly,the algorithm extracts a weak damping component which is associated with objective mode from each tie-line active power signal,and the signal comes from WAMS through a low-pass or band-pass filter which is designed by a priori... |
