Ways to prevent ferroresonance phenomena in a network with an isolated neutral

Ferroresonance is a phenomenon in electric power systems that can result in severe consequences, including increased short-circuit currents, equipment overload, and potential damage to transformers and other devices. To address these challenges, this study aims to explore and implement effective methods for mitigating ferroresonance. The research investigates different techniques employed by engineers and operators to prevent and manage ferroresonance occurrences in electric power systems. The primary objective of this work is to identify and analyze various methods used to mitigate ferroresonance, considering both preventive measures and reactive strategies. The study employs a combination of literature review, simulation studies, and practical case analyses to provide a comprehensive overview of the available techniques.The research results indicate that a combination of passive and active mitigation methods, such as damping resistors, surge arresters, and proper system grounding, can significantly reduce the impact of ferroresonance. Simulation studies are conducted to validate the effectiveness of these methods in different power system scenarios. In conclusion, the findings underscore the importance of implementing a multi-faceted approach to ferroresonance mitigation. The study contributes valuable insights into the selection and application of suitable methods for engineers and operators in electric power systems.
