Multi Generator Synchronization System - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240097584 titled 'Multi Generator Synchronization System
Simplified Explanation
The present disclosure contemplates a method for synchronizing a large number of generators on an AC bus simultaneously by closing the generator breakers when the generators are rotating but de-energized. Then excitation is raised for each generator simultaneously, causing the generators to synchronize as voltage increases, without large transient current surges that can damage the machines. In order to safely maximize the rate at which excitation is raised, initial excitation can be controlled using current regulation, specifically controlling excitation current instead of voltage. Once a predetermined voltage is reached, a control scheme can be switched to a voltage regulation mode, which brings the generator to the final desired voltage.
- Synchronization method for a large number of generators on an AC bus
- Closing generator breakers when de-energized but rotating
- Raising excitation simultaneously for each generator to synchronize
- Controlling excitation using current regulation initially, then switching to voltage regulation
- Minimizing transient current surges during synchronization
