Power Switch Cabinet Control for Dynamic Module Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power switch cabinets with power modules require manual power-down and adaptation for operational changes, such as fault recovery or load demand adjustments, leading to inefficiencies and high costs.
Innovation Solution
A controller and communication mechanism based on publish-subscribe mode automatically determines target enabled power modules and their output powers without powering down, using an information table to manage states and prioritize modules for seamless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual power-down and adaptation is performed for operational changes, then system reliability is improved through controlled shutdown, but productivity deteriorates due to downtime and manual intervention
Solution Approach 1:
The system automatically determines target enabled power modules and their output powers based on load demand and module states without requiring manual intervention. The controller dynamically adjusts power module configurations, enabling the system to serve itself and eliminate downtime associated with manual power-down and adaptation operations.
Solution Approach 2:
The system transitions from static manual configuration to dynamic automatic adjustment. The controller continuously monitors load demand and power module states, dynamically determining which modules to enable and their respective output powers, allowing the system to adapt in real-time without shutdowns.
2Ease of operation
If manual adaptation is performed for power module changes, then operational control is improved, but loss of time increases due to manual configuration requirements
Solution Approach 1:
The controller automatically determines target enabled power modules and their output powers based on load demand and module states without requiring manual intervention. The system self-configures when power modules are added or removed, eliminating the time loss associated with manual adaptation while maintaining operational control.
Solution Approach 2:
The system uses feedback from load demand signals and power module state information to automatically adjust the configuration of enabled modules. The controller receives feedback about which modules are available and their current states, then automatically determines the optimal configuration without manual input or downtime.
3Stability of the object's composition
If power switch cabinet is powered down for adaptations, then system stability is improved through controlled shutdown, but loss of time increases due to required power-down operations
Solution Approach 1:
The system enables dynamic reconfiguration of power modules during operation without requiring shutdown. The controller can add or remove power modules from active service while the system remains powered on, maintaining stability through controlled dynamic adjustment rather than static shutdown-and-restart cycles.
Solution Approach 2:
The system maintains continuous power supply and operational stability by enabling and disabling individual modules dynamically. When a module needs to be removed or added, the controller redistributes the load among remaining modules, ensuring continuous useful action without interruption to the overall system operation.
4Manufacturing precision
If additional adaptations are required for power module changes, then configuration precision is improved, but device complexity increases due to manual adaptation procedures
Solution Approach 1:
The controller automatically determines the precise configuration of target enabled power modules based on load demand and module states. The system self-configures by calculating which modules to enable and their respective output powers, eliminating the need for manual adaptation procedures and reducing system complexity while maintaining configuration precision.
Solution Approach 2:
The system replaces manual mechanical configuration procedures with automated electronic control. The controller uses electronic signals and algorithms to determine module configurations, substituting the complex manual adaptation process with a simpler automated system that achieves the same configuration precision without requiring manual intervention.
