Feeder Power Restoration via Master Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical power systems face challenges in efficiently and reliably restoring power to non-faulted sections of a feeder after a fault occurs, leading to prolonged outages and unnecessary service interventions.
Innovation Solution
A method and apparatus that utilize a master electronic device with stored power restoration plans to isolate faulted zones and reroute power from non-faulted sections to alternative feeders or sources, employing switching devices to execute selected restoration plans and reconnect loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fault isolation methods are used with manual intervention, then faulted zones can be isolated, but power restoration to non-faulted sections is delayed and requires unnecessary service interventions
Solution Approach 1:
The system pre-configures multiple restoration plans with predetermined switching sequences and alternative power paths before faults occur. When a fault is detected, the master electronic device automatically selects and executes the appropriate pre-planned restoration sequence, eliminating the need for manual intervention and significantly reducing restoration time
Solution Approach 2:
The master electronic device autonomously detects faults, selects appropriate restoration plans, and controls switching devices to restore power without requiring human operators. The system self-manages the entire fault isolation and power restoration process, continuously monitoring system status and automatically adjusting configurations to maintain power supply to non-faulted sections
2Adaptability or versatility
If the power distribution system maintains a fixed architecture, then system design is simplified, but the system cannot adapt to contingent fault conditions and restore power efficiently
Solution Approach 1:
The power distribution system dynamically reconfigures its architecture by automatically controlling switching devices to create alternative power paths based on detected fault conditions. The master electronic device adjusts the system configuration in real-time, transforming the fixed architecture into a dynamic, adaptive system that can respond to various fault scenarios while maintaining manageable complexity through automated control algorithms

AI summary
A method and apparatus for restoring power to loads connected to a feeder powered by a power source. The feeder is provided with a plurality of switching devices and a master electronic device which is in operative communication with the switching devices and has a plurality of power restoration plans stored therein. Upon occurrence of a fault in a zone of the feeder, the identity of the switching device which is closest to and upstream from the faulted zone relative to the power source is used in order to select a power restoration plan and restore power to some or all the loads connected to non-faulted zones of the feeder from one or more additional feeders.
