System and method for automatically providing continuous power supply via standby uninterrupted power supplies

A method for providing continuous power supply, the method being implemented in a power supply system including a plurality of primary UPSs and at least one standby UPS, the method comprising the steps of:

• monitoring the primary UPSs and electrically powered devices connected to the primary UPSs;
• determining whether there is any malfunction on the primary UPSs;
• determining whether a number of unworkable primary UPSs exceeds a number of the at least one standby UPS;
• starting as many of the at least one standby UPS as are needed for a continuous power supply when the number of unworkable primary UPSs does not exceed the number of the at least one standby UPS;
• starting all standby UPSs and sending out a shutdown instruction when the number of unworkable primary UPSs exceeds the number of the at least one standby UPS;
• and
• shutting down the electronically powered devices.

A method of automatically providing continuous power supply via a plurality of standby uninterrupted power supplies (UPSs) for an electrical device during a shutdown, comprising steps of:

• (1) providing a plurality of primary UPSs and said plurality of standby UPSs;
• (2) monitoring connection between the primary UPSs and the electrical device;
• (3) determining whether the shutdown is normal or not;
• (4) running a shutdown program if said shutdown is normal, or
• (5) checking whether any malfunction of said primary UPSs exists, if said shutdown is not normal;
• (6) starting a required number of the standby UPSs if said malfunction exists and an amount of said malfunctioned primary UPSs does not exceed that of the standby UPSs wherein said required number is same as the amount of the malfunctioned primary UPSs, or starting all the standby UPSs if said malfunction exists and the amount of said malfunctioned primary UPSs is not less than that of the standby UPSs;
• and running step (4).
