Title:
SAFETY POWER SUPPLY SYSTEM AND CONTROL METHOD THEREOF
Document Type and Number:
Japanese Patent JP2014155269
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a safety power supply system which comprises an AC connection type safety power source and is capable of operating a solar cell even during a power failure.SOLUTION: A safety power supply system 1 comprises: an AC electrical circuit 17 connected with a system 100; a reverse power transmission prevention device for preventing reverse power transmission in the case of a system power failure; a safety power source E including a photovoltaic power generation device 130 and a power storage device (power unit) 120; a safety facility 14 to which power is supplied by the safety power source E; and a safety power supply control device 18 for regulating power required by the safety facility 14 and power supplied by the safety power source E during a power failure of the system 100. During the power failure of the system 100, the power storage device 120 operates independently, and the photovoltaic power generation device 130 is operated cooperatively by the power storage device 120. When power supply is interrupted in the system 100, a power conditioner 13P such as a solar cell 13 which is operated cooperatively detects single operation and stops generating power normally but since it is masked (invalidated), the solar cell 13 is capable of continuously generating power.
