SYSTEM AND METHOD FOR ANTI-ISLANDING OF DISTRIBUTED POWER GENERATION

摘要

The present invention provides a fault determination module for determining the occurrence of a fault in the distribution system based on at least one of the current and voltage of the distribution system to which the distributed power source is linked, and reverse current sensing for detecting the occurrence of reverse current due to the independent operation of the distributed power supply. The module, provided between the distributed power supply and the distribution system, in response to detecting the occurrence of an overcurrent exceeding the distributed power generation capacity, blocks the connection between the distribution system and the distributed power supply, and is provided on the distribution system, It is characterized in that it comprises a protection device for controlling the connection of the distribution system based on the occurrence of a fault determined by the fault determination module and the occurrence of a reverse current detected through the reverse current detection module.
