Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional AC power systems experience inefficiencies due to unbalanced load distribution across phases, especially when variable output generators like solar or wind are connected to unbalanced premise installations, leading to reduced generator efficiency and increased energy losses.
Innovation Solution
A method for multiphase electrical power assignment involving a processor-controlled bi-directional power device that synchronizes its power signal with a specific phase connection, using phase connection switches to ensure accurate coupling and balanced power distribution by determining the appropriate phase and timing for connection, thereby avoiding faults and ensuring efficient power transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed wiring connection assignments are used from multi-phase generation source, then installation simplicity is improved, but load balance and generator efficiency deteriorate
Solution Approach 1:
The system dynamically assigns bi-directional power devices to specific phases based on real-time load conditions rather than using fixed wiring assignments. The processor continuously monitors phase loads and reconfigures connections to maintain balance, allowing the system to adapt to changing conditions and minimize energy losses while maintaining operational simplicity.
Solution Approach 2:
The system changes the connection parameters (which phase each bi-directional power device connects to) based on load conditions. By varying the phase assignment parameters dynamically rather than maintaining fixed assignments, the system achieves better load balance and reduced energy losses without compromising installation simplicity.
2Adaptability or versatility
If variable output generators (solar or wind) are connected to unbalanced premise installations, then renewable energy utilization is improved, but generator efficiency and system performance deteriorate
Solution Approach 1:
The system dynamically matches variable output generators to phases with appropriate load conditions. The processor monitors generator output and phase loads in real-time, continuously adjusting connections to ensure generators operate at optimal efficiency while maintaining overall system balance, thereby preserving both renewable energy utilization and generator efficiency.
Solution Approach 2:
The system uses feedback from load monitoring and generator output sensing to continuously optimize phase assignments. The processor receives feedback about current phase imbalances and generator performance, then adjusts connections to maintain optimal operating conditions, ensuring both high renewable energy utilization and generator efficiency.
3Speed
If bi-directional power devices are connected without phase synchronization, then connection speed is improved, but system reliability and fault prevention deteriorate
Solution Approach 1:
The system performs preliminary phase synchronization checks and timing adjustments before finalizing the connection of bi-directional power devices. By preparing the connection timing in advance and ensuring phase alignment is achieved before closing switches, the system maintains both fast connection speed and high reliability with proper fault prevention.

AI summary
In a multiphase electrical power assignment, a processor: receives instructions to connect a bi-directional power device to a multiphase premise power source; determines that the power device is to be coupled to a target phase's phase connection; confirms that the power device is not coupled to any phase connections; and couples the power device to the phase connection, where the power device's power signal is synchronized with the phase connection's power signal. When the power device is in a connected state, the processor: issues a command to place each phase connection switch in an open state; in response to confirming that the phase connection switches are in the open state, issues commands to the power device so that a power signal of the power device will be synchronized with the target phase; and closes the phase connection switch corresponding to the target phase.
