Power Supply Link Section Overload Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power supply systems face overloading issues due to high switch-on currents from multiple devices, which can lead to damage and require methods to prevent overloading without disrupting power distribution.
Innovation Solution
A method and device that determine requested power values for loads and compare them to maximum available power values for link sections, releasing power only if the request does not exceed the available capacity, using a regulating unit for authentication and authorization to manage power distribution efficiently across parallel link sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple devices with high switch-on current are connected to the power supply system, then the power distribution capacity is improved, but the transmission links may be overloaded causing damage
Solution Approach 1:
The regulating unit determines the requested power value and compares it with the maximum available power value before releasing the link section, performing preliminary checks to prevent overload before it occurs
Solution Approach 2:
The system continuously monitors the power consumption of loads and adjusts the available power value dynamically, using feedback from actual power usage to make real-time decisions about link section release
2Reliability
If fuses are used to prevent overload, then the transmission link safety is improved, but the entire power supply system is interrupted
Solution Approach 1:
The power supply system is divided into multiple link sections that can be independently controlled and released, allowing selective power distribution to different loads without affecting the entire system
Solution Approach 2:
The system dynamically adjusts the available power value for each link section based on real-time power consumption, enabling flexible and adaptive power distribution that responds to changing load conditions
3Reliability
If power is restricted to prevent overload, then the transmission link safety is improved, but the power availability for loads is reduced
Solution Approach 1:
The available power value is dynamically adjusted based on actual power consumption, allowing the system to optimize power distribution in real-time rather than using fixed restrictions
Solution Approach 2:
The system changes the power allocation parameters dynamically by determining requested power values and comparing them with maximum available power values, adjusting the released power accordingly

AI summary
A method and a regulating unit for avoiding overloads for link sections within a power supply system use requirements for loads to determine which link sections can be enabled for loads.
