ISOLATION OF FAULTED SECTION FOR SHORT-CIRCUIT FAULT IN INVERTER-BASED REMOTE MICRO-GRID

摘要

The present invention relates to an intelligent switch provided on a line in a stand-alone micro grid for controlling opening or closing of a line, a battery inverter having a built-in current limiter and capable of limiting an output current, And an operating system for controlling the battery inverter to limit the output current by receiving the fault current and controlling the output current of the battery inverter. The inverter-based standalone micro grid in-line short-circuit fault section switching system and the switching method are separately provided, such as a recloser It is possible to quickly and accurately transfer the line short-circuit fault section occurring in the stand-alone micro-grid, which is not provided with the shut-off facility of the line breaker.
