DISTRIBUTED POWER SYSTEM
Document Type and Number:
Japanese Patent JP2014147231
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a distributed power system that continues operating a power generation device as far as possible when power supply from a power system to an AC line becomes abnormal.SOLUTION: In the distributed power system, a power generation device 20 is configured to control supply power from power generation means 21 to an AC line 2 if power quality of the AC line 2 satisfies an interconnection mode or self-sustaining mode power quality condition and electrically disconnect the power generation means 21 from the AC line 2 if the power quality of the AC line 2 does not satisfy the interconnection mode or self-sustaining mode power quality condition, when a power supply control section 12 of an auxiliary power supply device 10 operationally controls power storage means 11 in each of an interconnection operation state or self-sustaining operation state. The power quality is at least either power voltage or frequency, the power quality condition is that an allowable deviation from reference power quality is maintained, and the allowable deviation for the self-sustaining mode power quality condition is larger than the allowable deviation for the interconnection mode power quality condition.
