Abstract
The expanding distributed power grids have elevated performance expectations for transmission equipment in power systems, emphasizing the crucial need to enhance stability and reliability in the electric power industry's development. This study presents the development and validation of a novel non-superconducting fault current limiter (NSFCL) for enhancing the reliability and stability of electrical distribution grids. The using of the high power and self-turn off solid-state switches is one of the main reasons for effectively reducing fault currents during transient events, and also improves the characteristics of NSFCL, including high voltage and current ratings, low losses and good performance. The device's performance was rigorously tested through simulation and experimental trials, demonstrating its effectiveness in limiting interrupting fault currents while maintaining grid integrity. This novel solution holds significant promise for enhancing the reliability and resilience of electrical distribution networks by efficiently mitigating fault currents, thereby contributing to improved grid stability and reduced downtime.
