APPARATUS FOR PROTECTING SOLAR POWER GENERATING SYSTEM AND METHOD FOR PROTECTING SOLAR POWER GENERATING SYSTEM

摘要

The present invention senses and resolves series and parallel arcs using a simple and highly reliable configuration. The apparatus for protecting a solar power generating system determines whether or not there is an arc when a first relay (41P, 41N) is closed and second and third relays (42, 43p, 43N) are open; discriminates between parallel and series arcs when the first relay (41P, 41N) and second relay (42) are closed; and opens the first relay (41P, 41N) when a series arc occurs and closes the third relay (43p, 43N) when a parallel arc occurs.
