Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing static transfer switch (STS) systems for decentralized power supply have centralized control architectures, which are prone to single points of failure, are complex to assemble, and lack modularity, leading to increased costs and reduced flexibility.
Innovation Solution
The implementation of decentralized STS systems with integrated control within the AC switch assemblies, allowing for modular configuration, reduced complexity, and increased flexibility, along with redundant control and fault management to enhance reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized control architecture is used in STS systems, then control functionality is consolidated, but single points of failure are created and system reliability decreases
Solution Approach 1:
The patent divides the centralized control architecture into decentralized control modules distributed across multiple AC switch assemblies. Each assembly includes its own controller that can independently monitor power sources and execute transfer operations, eliminating the single point of failure in centralized systems while maintaining coordinated control functionality.
2Ease of manufacture
If modular configuration is implemented in STS systems, then assembly simplicity and flexibility are improved, but integration complexity increases
Solution Approach 1:
The patent designs AC switch assemblies with universal interfaces and standardized communication protocols that enable modular configuration. Each module can perform multiple functions (monitoring, control, protection) and can be independently assembled and integrated, simplifying manufacturing while managing integration complexity through standardized connections.
3Adaptability or versatility
If decentralized control is implemented in STS systems, then system flexibility and modularity are increased, but control coordination difficulty increases
Solution Approach 1:
The patent implements feedback mechanisms where decentralized controllers continuously monitor system state and exchange information with adjacent modules. This feedback loop enables automatic coordination of power transfer operations across distributed modules, maintaining system flexibility while reducing coordination complexity through real-time communication and adaptive control.
Data Source
AI summary
A static transfer switch (STS) system for transferring power between power sources is provided. The STS system includes first and second alternate-current (AC) switch assemblies. The first AC switch assembly includes a first current interrupter, and a first controller configured to control the first current interrupter. The second AC switch assembly includes a second current interrupter, and a second controller configured to control the second current interrupter. The first AC switch assembly and the second AC switch assembly are in communication with one another and are each configured to monitor an output power to the load, the first power source, and the second power source and transfer power when disturbance is detected in the output power, the first power source, and/or the second power source.
