Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Variable frequency electrical generating systems face challenges in performing no-break power transfers between sources operating at different frequencies, leading to undesirable effects like electronic equipment resets and power interruptions, which are difficult to manage with complex control systems.
Innovation Solution
A method and device utilizing a temporary power source to adjust its output frequency to match the frequency of the first power source, disconnect the first source, and then match the frequency of the second power source, allowing seamless coupling to the power bus without interrupting power, using a controller and energy storage device to facilitate the transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex control system is used to adjust power source frequency and phase for no-break transfer, then power transfer reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a temporary power source as an intermediary device to facilitate power transfer between two power sources operating at different frequencies. The temporary power source couples to the power bus, receives power from the first power source, and then transfers power to the second power source, enabling no-break transfer without requiring complex frequency and phase adjustment control systems.
Solution Approach 2:
The power transfer process is divided into distinct segments: the temporary power source first receives power from the first power source at its original frequency, then switches to supply power at the second power source's frequency. This segmentation allows each power source to operate independently at its own frequency without requiring complex coordination control.
2Device complexity
If break-type power transfer is used between different frequency sources, then device complexity is reduced, but harmful effects increase
Solution Approach 1:
The temporary power source acts as a mediator that maintains continuous power supply to the power bus during the transfer process. By receiving power from the first source and supplying power to the bus during the transition, it prevents the power interruptions and equipment resets that would otherwise occur with break-type transfer methods.
Solution Approach 2:
The temporary power source ensures continuous power delivery to the power bus throughout the frequency transition process. While the first power source is disconnected, the temporary power source maintains power supply, and then seamlessly transfers to the second power source's frequency, ensuring uninterrupted power delivery and eliminating harmful effects.

AI summary
A method is provided for using a temporary power source to transfer a power bus from a first power source to a second power source. The first power source operates at a first electrical frequency, and the second power source operates at a second electrical frequency that is different from the first electrical frequency. The method includes adjusting the output frequency of the temporary power source to match the first electrical frequency and supplying power to the power bus from the temporary power source. The method also includes disconnecting the first power source from the power bus. The method further includes adjusting the output frequency of the temporary power source to match the second electrical frequency. The method further includes coupling the second power source to the power bus.
