If asynchronous conditions occur, such as when synchronizing the generators, the speed is automatically adjusted to the power frequency and the generator voltage in an electrical power system. System, for which a wider switching angle can be permitted. If the frequency difference is almost zero for a long time, this is referred to as a synchronous electrical power
“Switching synchronous electrical power systems” operating mode the frequency difference is measured with a high level of accuracy. The SIPROTEC 7VE85 recognizes the operating conditions automatically and reacts in accordance with the settings. Flexibly adjustable and expandable I/O quantity structure within the scope of the modular SIPROTEC 5 system 1/6 expansion modules can be added, available with large or small display, or without display.1.5- and 2-channel synchronization function.
