Patent EP-4307554-A1 (EP)
Title: Multi generator synchronization system
Inventor: GUBBA RAVIKUMAR KRISHNANJAN
IPC: H02P9/08
Filed: 2023-05-25
Abstract: 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.

Abstract: It is common that communications such as telephone calls between calling and called lines be made by sharing a single communications path on a time division basis. Each call is assigned to a shared path for a short time interval, also called a time slot. It is known to interchange an input time slot to a different output time slot. Unfortunately, known time slot interchange arrangements insert an input sample in a single output time slot. The instant time slot interchanger extends an input sample onto a plurality of output time slots for broadcasting a sample through a plurality of locations. Also, the instant time slot interchanger may selectively insert an alternate message, e.g., an error message, in an output time slot.
