本文提出了一种利用多元分析技术监测区域间振荡频率和阻尼的新方法。本文提出了一种两步法：1）独立分量分析法用于区域间模态的检测和频率估计; 2）随机衰减法用于模态阻尼的估计。该方法适用于真实的测量在芬兰的北欧电力系统内，以估计系统中的临界区域间模式频率和阻尼。
This paper presents a novel approach to the monitoring of interarea oscillation frequency and damping using multivariate analysis techniques. A two-step method is presented 1) independent component analysis for the detection of interarea modes and estimation of their frequencies and 2) random decrement for the estimation of mode damping. The method is applied to real measurements taken in Finland within the Nordic Power System to estimate the critical interarea mode frequency and damping in the system.
