Line short-circuit fault section switching system and switching method in inverter-based independent microgrid

摘要

The present invention provides a plurality of intelligent switches that are provided on a line in a stand-alone microgrid to control the opening or closing of the line, a battery inverter that incorporates a current limiter and can limit output current, and the plurality of Line short circuit in an inverter-based stand-alone microgrid including an operating system that receives the short circuit fault information of the line from an intelligent switch to determine a fault zone and control the battery inverter to limit output current A fault section switching system and switching method that can quickly and accurately switch a line short-circuit fault section that occurs in an independent microgrid that does not include a separate shut-off facility such as a recloser. .
