Three-Phase Compensation Circuit for Power Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide a three-phase power supply when one or two phases malfunction, requiring alternative power sources, which may not be available, leaving consumers without electricity.
Innovation Solution
A three-phase compensation system using an electric circuit with control relays that can redirect current from functioning phases to ensure continuous three-phase power supply, even if one or two phases are unavailable, utilizing a configuration of normally open and closed contacts within the control relays to maintain operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If substituting power sources such as generators are used to compensate for lost phases, then power supply continuity is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces an intermediary device (the compensation system with relays and contacts) that mediates between the available phases and the required three-phase output. This intermediary redirects and reconfigures existing phase connections to synthesize the missing phases, avoiding the need for complex substituting power sources while maintaining power supply continuity
Solution Approach 2:
The compensation system performs multiple functions: it detects phase failures, reconfigures connections, and synthesizes missing phases using the same infrastructure. This multi-functionality allows the system to maintain three-phase power supply without requiring separate substituting power sources, thereby reducing overall system complexity
2Reliability
If substituting power sources are used to compensate for lost phases, then power supply reliability is improved, but cost increases
Solution Approach 1:
The compensation system is self-service in that it automatically detects phase failures and reconfigures connections without external intervention or additional power sources. The system uses the existing phase infrastructure to compensate for itself, eliminating the need for expensive external generators or backup power sources
Solution Approach 2:
The system changes the connection parameters (phase relationships) dynamically based on detected failures. By altering how phases are connected and distributed through the relay contacts, the system maintains three-phase power supply using the same physical infrastructure, avoiding the cost of additional power sources
3Device complexity
If consumers have no alternative power provider, then system simplicity is maintained, but power supply reliability deteriorates when phases malfunction
Solution Approach 1:
The compensation system performs preliminary actions by pre-configuring relay contacts and detection circuits that are ready to immediately respond to phase failures. When a phase malfunction occurs, the system has already positioned the necessary components to rapidly reconfigure connections and restore three-phase power, maintaining reliability without adding complex alternative power providers
