Electric Network Phase Mapping via Dynamic Topology Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing electric energy distribution in networks face challenges due to mismatched phase topologies between consumers and management units, leading to inefficiencies and incorrect control commands when supplying electric current or voltage.
Innovation Solution
A method that dynamically manages electric energy by determining and mapping the phases used to supply consumers through predefined consumption patterns transmitted via communication interfaces, using sensors to capture changes in voltage and current, and creating a network map to ensure accurate phase assignment and energy distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a management unit uses a fixed topology assumption to control phase supply, then control simplicity is improved, but phase assignment accuracy deteriorates when consumer topology differs from assumption
Solution Approach 1:
The patent applies dynamics by transitioning from a static topology assumption to a dynamic topology detection approach. The management unit actively probes the consumer device by sending test signals on different phases and observes the responses to dynamically determine the actual phase connections. This allows the system to adapt to any consumer topology configuration rather than relying on fixed assumptions.
Solution Approach 2:
The patent implements feedback by having the consumer device respond to management unit probes with information about its phase connections. The management unit sends test signals and receives feedback about which phases are actually connected to the consumer, allowing it to update its topology understanding and make accurate control decisions based on real consumer configuration.
2Device complexity
If phase topology is not dynamically determined, then system complexity is reduced, but energy distribution efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by performing topology detection before actual energy distribution begins. The management unit sends probe signals and determines phase connections in advance, creating an accurate topology map that guides subsequent energy distribution decisions. This preliminary characterization enables efficient energy distribution without requiring complex real-time analysis during operation.
3Productivity
If consumption patterns are transmitted to consumers, then energy distribution optimization is improved, but communication overhead increases
Solution Approach 1:
The patent applies local quality by transmitting customized consumption patterns specifically tailored to each consumer device and its detected topology characteristics. Rather than broadcasting generic patterns to all devices, the management unit sends targeted patterns that match the specific phase connections and operational characteristics of each consumer, making the communication highly relevant and efficient.
