Abstract

The embodiment of the invention discloses a method and a system for evaluating the three-phase unbalance degree of a data center. The method comprises the following steps: obtaining the branch currentof each cabinet of the data center; Calculating a total current of each phase of three-phase electricity according to the branch current; Calculate the load rate of the circuit, when the load rate exceeds the unbalanced degree, calculate the maximum three-phase current unbalanced degree; The maximum three-phase current unbalance degree is compared with the three-phase current unbalance degree limit value to judge the three-phase unbalance degree. The invention considers the influence of the load rate on the three-phase unbalance, prolongs the service life of the UOS, reduces the coefficient of false alarm of the UOS, and improves the reliability of the operation of the data center.

Description

technical field [0001] The invention relates to the technical field of data centers, in particular to a method and system for evaluating the three-phase unbalance degree of a data center. Background technique [0002] The three-phase unbalance of the power system is mainly caused by the asymmetry of the three-phase load, and the unbalanced distribution of the single-phase load in the three-phase system among the power users will also cause the appearance of the three-phase unbalance. [0003] With the large-scale construction of data center technology, the problem of three-phase imbalance is becoming more and more prominent, and the loss and damage to UPS are increasing. When the load rate is large, the UPS ((Uninterruptible Power System / Uninterruptible Power Supply , that is, the service life of the uninterruptible power supply); when the load is small, it will cause the UPS utilization rate to drop, and at the same time, it will cause false alarms of the UPS three-phase un...
