UPS Control Assembly for Industrial Power Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power installations with uninterruptible power supply (UPS) systems face challenges in efficiently controlling power distribution, especially in industrial, offshore, or marine settings with non-standard configurations, requiring enhanced voltage/current control and isolation capabilities, and often lack flexibility to adapt to varying system requirements and legal standards.
Innovation Solution
The introduction of an installation control assembly with an assembly controller and measurement devices, galvanically referenced to system Protective Earth, allows for supervisory control of both the UPS system and controllable hardware components, enabling efficient power supply management and adaptation to specific needs without major changes to existing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard UPS system is used with basic control capability, then the cost is reduced and the system is simpler, but the adaptability to different installation types and national legal requirements is insufficient
Solution Approach 1:
The control device is designed to perform multiple functions: it controls both the UPS system and controllable hardware components, supports various installation types (TN-(C)-S, IT, industrial, offshore, marine), and can adapt to different national legal requirements. This multi-functional design eliminates the need for separate control systems for different applications.
Solution Approach 2:
The control device is divided into functional modules: a microcontroller unit for core control, measurement devices for monitoring voltages and currents, and communication interfaces for configuration and status reporting. This modular structure allows the system to maintain low base complexity while providing high adaptability through software configuration.
2Ease of operation
If a standard UPS system with minimum control capability is used, then the device complexity is reduced, but the control capability for voltage/current and operation of disconnect devices in non-standard configurations is insufficient
Solution Approach 1:
The control device merges the functions of UPS control and controllable hardware component control into a single integrated unit. It can control disconnect devices, switches, and other hardware components in addition to managing the UPS system, thereby providing comprehensive control capability without requiring separate control systems.
Solution Approach 2:
The control device incorporates measurement devices that continuously monitor voltages and currents in the system. This feedback information is used by the microcontroller to automatically adjust control parameters, ensure safe operation, and comply with legal requirements for voltage/current control in various installation types.
3Adaptability or versatility
If additional application-specific sense capability and control capability are added to handle multiple transformers and controls/switch gears, then the adaptability to industrial, offshore, or marine installations is improved, but the device complexity increases
Solution Approach 1:
The control device employs dynamic configuration capabilities where the system can be programmed and adapted to different installation types through software settings rather than hardware changes. The microcontroller can dynamically adjust control parameters based on the detected installation type (industrial, offshore, marine) and specific configuration requirements.
