Reverse Power Feeding Load Balancing via Port Link Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In reverse power feeding systems, when reverse power feeding is interrupted from a specific customer premise, the load balancing among multi-ports at the distribution point becomes unstable, leading to increased power burden on remaining customer premises and potential communication service disruptions due to unnecessary power consumption by idle communication ports.
Innovation Solution
An apparatus and method that senses power interruptions in real-time, immediately blocks the link of the communication port connected to the interrupted customer premise, and performs load balancing only among remaining communication ports to maintain stable power consumption and operation of the DPU, thereby reducing overall power consumption and ensuring continuous communication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the distribution point continues to maintain communication port links after reverse power feeding interruption from a customer premise, then communication service availability is preserved, but unnecessary power consumption increases and stabilizes the power burden on remaining customer premises
Solution Approach 1:
The distribution point continuously monitors reverse power feeding status from multiple customer premises and uses this feedback information to dynamically control communication port links. When power feeding interruption is detected from a specific customer premise, the system automatically releases the corresponding communication port link to prevent unnecessary power consumption while maintaining service stability for other active customers.
Solution Approach 2:
The system transitions from a static communication port configuration to a dynamic one where port links are actively controlled based on real-time power feeding status. The distribution point can selectively establish or release communication port links according to which customer premises are currently providing reverse power, optimizing both power consumption and service availability.
2Use of energy by moving object
If the distribution point releases communication port links immediately upon detecting reverse power feeding interruption, then power consumption is reduced, but communication service continuity may be affected
Solution Approach 1:
The system uses real-time feedback from power status monitoring to trigger link release only when necessary. By continuously detecting reverse power feeding status, the system ensures that communication port links are released only when power feeding interruption is confirmed, preventing premature or unnecessary service disruption while optimizing power consumption.
Solution Approach 2:
The distribution point performs preliminary detection and verification of power feeding status before executing link release. This preliminary action ensures that the system accurately identifies genuine power interruptions and avoids false triggers, thereby maintaining communication service stability while still achieving power savings.
3Adaptability or versatility
If the distribution point performs load balancing among all communication ports including inactive ones, then service availability is maintained, but power burden on remaining customer premises increases
Solution Approach 1:
The system segments the set of communication ports into active and inactive groups based on which customer premises are currently providing reverse power. Load balancing is then performed only among the active ports, excluding inactive ones from the calculation. This segmentation ensures that power burden is distributed fairly among remaining customer premises while maintaining service availability for active connections.
Solution Approach 2:
The load balancing mechanism dynamically adapts to changing power feeding scenarios by reconfiguring which ports are included in the load balancing calculation. When a customer premise stops providing power, its corresponding port is automatically excluded from load balancing, allowing the system to adapt to the new configuration and distribute power burden appropriately among remaining active ports.

AI summary
The present invention relates to an apparatus and a method for load balancing among multi-ports in reverse power feeding, and more particularly, to an apparatus and a method which, in the process in which a distribution apparatus performs load balancing among multi-ports by reversely receiving power from multiple customer premises at a distribution point, when reverse power feeding from a specific customer premise is stopped, since a power burden of a remaining customer premise is increased, which interfere with a communication service, can reduce power consumption on the distribution by releasing a link of a communication port connected with the corresponding customer premise as soon as the power feeding is stopped and provide a stable communication service by performing the load balancing only with respect to remaining communication ports.
