Title:
DC POWER SUPPLY SYSTEM, POWER SOURCE SUPPLY DEVICE, AND POWER SUPPLY CONTROL METHOD AND PROGRAM IN DC POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2015164373
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a DC power supply system capable of supplying power to a power supply path by starting up a PCS of a photovoltaic power generation device in an outage state in which operation voltage capable of enabling the PCS to operate is not supplied from a power source system interconnecting with the DC power supply system.SOLUTION: A DC power supply system 1 includes: a DC power source device 3 that outputs DC voltage to supply power to a load device connected to a power supply path of the DC power source device 3; a photovoltaic power generation device 4 that is connected to the power supply path through a PCS 5 to supply power to the power supply path; and a power source supply device 6 that supplies the PCS 5 in a stop state in which output of the PCS stops with operation voltage for enabling the PCS to output power. The power source supply device 6 supplies operation voltage to the PCS 5 to start up the PCS 5, when the PCS 5 becomes in the stop state and the operation voltage for enabling the PCS 5 to output power is not supplied from the DC power source device 3 to the PCS 5.
