Method and device for power supply fault handling

Abstract

The invention discloses a power supply fault processing method and device. The method is applied to a data center system which comprises multiple apparatuses and an uninterrupted power source, and the uninterrupted power source is used to supply power to the multiple apparatuses when the apparatuses are in an abnormal power supply state. The method is characterized by comprising the steps that the power supply state of the apparatuses is monitored; when the abnormal power supply state is detected, a power-off protection strategy, which includes the power-off protection priority levels of the protected apparatuses, of the apparatuses is obtained; and when the uninterrupted power source supplies power, the protected apparatuses are successively powered off according to the power-off protection priority levels. The problems of the prior art that not all the apparatuses can be powered off within the effective power supply time of the uninterrupted power source due to limited power supply capability of the uninterrupted power source and abnormal power off still occurs are solved.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a method and device for handling power supply failures. Background technique [0002] In order to facilitate the centralized management and maintenance of business systems by enterprises, enterprises usually establish data center systems. The data center system can include multiple devices, and each device will run one or more business systems. In order to prevent devices in the data center system from When the mains power supply fails, the power supply is cut off. In the prior art, the data center system is usually equipped with an uninterruptible power supply UPS (Uninterruptible Power System). In this way, when a power supply failure occurs, the power supply system of the data center system is switched to the UPS, thereby It can ensure that the equipment in the data center system can maintain normal operation within a certain period of time, and the user can deal with the...
