Data Center Phase Load Reallocation for Three-Phase Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unbalanced phase power loads in data center systems lead to power wastage and limited utilization of three-phase power sources, causing excessive heating and tripping of circuit breakers, which can result in safety failures.
Innovation Solution
Implementing phase power load balancing by extracting phase currents, determining input phase power load balancing for a subset of systems, and altering it through power shifting, phase rotations, or input phase switching of PDU switchable output ports to achieve balanced power distribution.

Engineering Contradiction Analysis
1Ease of operation
If individual systems balance their input phases independently, then each system achieves local phase balance, but the overall infrastructure phase balance remains uncorrected due to multiple unbalanced systems
Solution Approach 1:
The patent combines the phase balancing operations of multiple individual systems into a coordinated group-level balancing operation. By merging the control of phase distribution across several systems, the infrastructure achieves overall phase balance that individual system balancing cannot accomplish alone.
Solution Approach 2:
The patent creates a universal phase balancing mechanism that operates across the entire infrastructure rather than being limited to individual systems. This multi-functional approach allows the same balancing principles to be applied system-wide, correcting aggregate phase imbalances affecting the whole data center.
2Device complexity
If unbalanced phase power loads are maintained in individual systems, then system-level control is simple, but power wastage increases and circuit breakers trip due to excessive heating
Solution Approach 1:
The patent implements feedback mechanisms that monitor phase power loads across the infrastructure and automatically adjust phase distribution to prevent excessive imbalances. This closed-loop control reduces power wastage by dynamically responding to changing load conditions without requiring complex manual intervention.
Solution Approach 2:
The patent changes the operational parameters of phase power distribution by allowing flexible reallocation of phase loads across multiple systems. This dynamic parameter adjustment optimizes power utilization and prevents the excessive heating that leads to circuit breaker tripping, while maintaining manageable control complexity.

AI summary
Disclosed embodiments provide methods, systems, and computer program products for implementing enhanced phase power load balancing of a set of systems (e.g., the set of systems of a data center) using a subset of the systems. Disclosed embodiments extract phase currents of a three-phase power source of the set of systems, and determine, based on extracted phase currents for the set of systems, input phase power load balancing for the subset of the systems. Disclosed embodiments alter the current input phase power balancing of the subset, unbalancing the input phase power load for the subset of the systems to provide enhanced phase power load balancing of the set of systems. Altering the current input phase power balancing for the subset of the systems can be implemented by power shifting between power supply units (PSUs), phase rotations, or input phase switching of power distribution unit (PDU) switchable output ports.
