Title:

POWER CONDITIONER, POWER SYSTEM, CONTROL METHOD OF POWER CONDITIONER

Document Type and Number:

Japanese Patent JP2019083689

Kind Code:

A

Abstract:

To provide a control arrangement of power conditioner capable of continuing power supply to a load, without stopping autonomous operation by the output power from other power conditioner in linked operation, when the power conditioner to be connected with an accumulator battery during electric outage of the system is operating autonomously.SOLUTION: A control arrangement of a power conditioner connected with an accumulator battery and configured to perform autonomous operation during electric outage of the system includes monitoring means for monitoring the charge power charging the accumulator battery, an AC power line connected with a power generator and connecting the power conditioner with other power conditioner and a load configured to perform linked operation, and instruction means for giving instructions to a bidirectional power converter for converting power bidirectionally between the accumulator battery and itself. When the charge power satisfies predetermined conditions, the instruction means instructs the bidirectional power converter to change the output voltage to AC power line.SELECTED DRAWING: Figure 4
