POWER CONVERSION APPARATUS, POWER CONVERSION SYSTEM, AND ISLANDING OPERATION DETECTION METHOD

摘要

When islanding operation is to be detected in a power conversion apparatus for converting a DC power into an AC power and outputting the AC power to a system power supply, a plurality of variation generation systems for executing, in accordance with different schemes, detection of islanding operation in which power supply from the system power supply is stopped are arranged, and at least one variation generation systems is selected by selection system from the plurality of variation generation systems and operated.
