摘要
PROBLEM TO BE SOLVED: To provide a distributed power generation system that is provided with an isolated operation preventing function with which isolated operation is prevented without fail even in high-density linked state and is free from reverse power flows to the system power supply side.;SOLUTION: The distributed power generation system that can be linked with a system power supply 30, comprises an underpower relay 5, a passive isolated operation preventing device 6, and an active isolated operation preventing device 7. The distributed power generation system is so constructed that a reverse power flow to the system power supply 30 side is not permitted. The generation output is controlled based on a target value of generated output. This target value is set with a predetermined allowance provided so that power becomes further insufficient relative to a set value of parallel off as a reference value for detecting underpower in the underpower relay.;COPYRIGHT: (C)2005,JPO&NCIPI
