Line Module Power Control for PDU Current Threshold Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power distribution systems for network devices are costly and difficult to modify to accommodate varying power requirements, particularly when network devices draw currents exceeding the maximum current rating, leading to risks of fuse blowing and circuit breaker tripping.
Innovation Solution
A method and system for power management that determines the maximum current rating of a power distribution unit (PDU) driven by a DC power plant with backup batteries, calculates the maximum aggregate current for line modules, and allocates current thresholds to prevent excessive current draw, thereby preventing fuse blowing and circuit breaker tripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power distribution system is designed with high current capacity to accommodate network devices with higher power requirements, then the power requirements of network devices can be met, but the cost and complexity of the power system increases
Solution Approach 1:
The patent implements dynamic current threshold allocation that adjusts power distribution based on real-time conditions. The system calculates maximum aggregate current for line modules and dynamically allocates current thresholds from each PDU feed, allowing the power system to adapt to varying power requirements without requiring a permanently oversized power distribution infrastructure.
2Reliability
If the maximum current rating of the PDU is increased to prevent fuse blowing and circuit breaker tripping, then system reliability improves, but the cost of the power system increases
Solution Approach 1:
The patent changes the operational parameters of existing PDUs by implementing intelligent current threshold allocation. Instead of increasing hardware ratings, the system modifies how current is distributed and monitored by calculating maximum aggregate current and allocating appropriate thresholds to each line module, thereby preventing fuse blowing and circuit breaker tripping with the existing power infrastructure.
3Reliability
If current thresholds are allocated to line modules to prevent excessive current draw, then fuse blowing and circuit breaker tripping are prevented, but the power distribution control complexity increases
Solution Approach 1:
The patent enables the power distribution system to self-regulate through automated current threshold allocation. The controller automatically calculates the maximum aggregate current for line modules and allocates appropriate current thresholds from each PDU feed without requiring manual intervention, allowing the system to protect itself against excessive current draw while maintaining operational simplicity.
