Abstract

Transient stability in interconnected power systems remains a pivotal concern for operators, particularly amidst the ever-expanding and intricate nature of modern power grids. This study delves into a novel approach to bolstering power grid stability by proposing the implementation of dual-excited synchronous generators (DESGs). Unlike conventional synchronous generators, DESGs feature dual windings on the rotor, strategically positioned to optimize performance and stability. This paper presents a thorough assessment of synchronous generators and DESGs under varying fault conditions, including three-phase to ground, two-phase to ground, and more. Leveraging advanced simulation techniques in Matlab/Simulink, the dynamic behavior and stability of these generators are meticulously analyzed. The results unveil a paradigm shift: DESGs exhibit superior stability and dynamic performance compared to their conventional counterparts across diverse fault scenarios. By harnessing the advantages of DESGs, including enhanced efficiency, the overall stability and reliability of power grids can be significantly augmented. In summary, this study not only sheds light on the critical importance of power grid stability but also presents a promising solution in the form of DESGs. By pushing the boundaries of traditional generator technology, this research paves the way for a more resilient and efficient electrical infrastructure.
