The real-time identification of low-frequency electromechanical oscillations within interconn- ected power systems is of significant interest due to its vital role in assessing the system’s stability status. These oscillations are often comprised of multiple modes, each with distinct frequencies and damping characteristics. This study introduces a measurement-based approach for determining the parameters of multi-mode electromechanical oscillations. The proposed method operates sequentially, making it ideal for real-time analysis of data gathered from Phasor Measurement Units in power systems. This approach is based on enhancing the parallel framework of an existing technique known as the Damped Second Order Generalized Integrator. The document elaborates on the newly suggested cascade configuration and offers simulation findings to validate both the theoretical analysis and the effectiveness of the proposed method. The method boasts several benefits: it supports real-time application as it processes data sequentially, exhibits resilience to noise without necessitating external pre-filtration or additional data preprocessing, can ascertain the immediate amplitude of oscillations, and is straightforward to design and execute. |
