PROBLEM TO BE SOLVED: To provide a technology for realizing continuation of stable power generation using a distributed power supply without using a communication channel.SOLUTION: An autonomous operation-correspondence distributed power supply 3 comprises an inverter 27, an autonomous operation dedicated frequency detection unit 22 and a single operation detection threshold change unit 23. The inverter 27 performs adjustment of voltage and a frequency of the power supply when system connection between the inverter 27 and an interconnection point of an autonomous operation system is established. The autonomous operation dedicated frequency detection unit 22 determines, by monitoring a quantity of electricity of the interconnection point, whether or not autonomous operation has started. The single operation detection threshold change unit 23 changes a threshold to be used for detecting single operation, on the basis of a result of the determination by the autonomous operation dedicated frequency detection unit 22.SELECTED DRAWING: Figure 1 |
