Abstract:Series resonant fault current limiter(SRFCL) is practical limiter of EHV. SRFCL control strategy requires resonant capacitor quickly bypassed after fault occurs. Shortcircuit fault rapid identification is the key to fast trigger strategy. The paper introduces resonant voltage difference method based on limiter body signal. Simulation model is built to analysis time characteristics from the closing angles and fault distance. Logic protection criterion is designed. A small physical model is built to verify the r… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
