Power Controller Backup Storage for Line Fault Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power systems face challenges when a short circuit or disconnect occurs in the power lines connecting power regulators to the power system controller, as the controller may not have the necessary power to perform operations.
Innovation Solution
The power system controller is configured to employ power from a power storage unit during short circuits or disconnects, allowing it to maintain operation and facilitate communication with power regulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power system controller uses power from the power lines connecting power regulators to itself, then it can operate during normal conditions, but it cannot operate when a short circuit or disconnect occurs in those power lines
Solution Approach 1:
The patent introduces a power storage device as an intermediary between the power lines and the power system controller. This mediator stores electrical energy and provides it to the controller when the power lines are disrupted, enabling the controller to operate independently of direct power line connections during short circuits or disconnects.
Solution Approach 2:
The power storage device is charged in advance during normal operation when power lines are functional. This preliminary energy accumulation allows the controller to operate autonomously when power line disruptions occur, without requiring real-time power line connectivity.
2Reliability
If the power system controller is designed to operate without power from power lines during disruptions, then it maintains operation during faults, but the system complexity increases
Solution Approach 1:
The power storage device serves multiple functions: it acts as a backup power source during disruptions, provides preliminary charging during normal operation, and enables the controller to operate independently. This multi-functionality justifies the added complexity by providing comprehensive operational reliability across different system states.

AI summary
A power system may comprise a power system controller and a power storage. The power system controller may comprise a first pair of power terminals, a second pair of power terminals, at least one switch, and a central controller coupled to the at least one switch. The power storage may comprise storage power terminals connected to the first pair of power terminals. The second pair of power terminals may be coupled to a power source. The power system controller may be configured to control the switch to connect and disconnect the second pair of power terminals. The power system controller may be configured to receive power from the power storage during a process of connecting and disconnecting the second pair of power terminals.
