Abstract
An islanding detection apparatus minimizes a reduction in power quality and detects islanding when distributed generations are operated in parallel. Also, another islanding detection apparatus for parallel distributed generations synchronizes parallel distributed generations by periodically applying a reactive current at a half cycle. Further, another islanding detection apparatus for parallel distributed generations easily synchronizes parallel distributed generations even when inverters installed in the respective distributed generations are fabricated through different makers.
