This mini-lecture delves into the analysis of eigenvalues and local modes in generator systems, using Starrett's example. We explore five key local modes, discussing their characteristics and behaviors, with eigenvalues such as -0.0251 + j8.9844 for Mode 1 and -0.0253 + j6.9133 for Mode 4, among others. Additionally, we analyze interarea modes that compare performance across several modes, specifically modes 1, 2, 4, and 5. This session aims to enhance understanding of dynamic stability and responsiveness in generator system operations.
